Kei Yotsuki

Major Character "I've always been in the shadows of others. One of my friends was an Uchiha, skilled in Flying Thunder God and white fire, and the other jinchūriki of the Eight Tails, who eventually became Raikage. Even was renowned in his own right. That left me to light my own way, by my own right. I turned to my affinity, and it provided. Lightning is an unstoppable force, that can take you down in an instant. And I've tamed the greatest powers of lightning, and made them my own. Don't count me out, or you'll shockingly regret it."

- Kei.

Kei Yotsuki (Light of the Night Moon, 夜月明い, Yotsuki Kei) addressed by most by his codename, K is the head of the ANBU of Kumo, a high ranking member of the Yotsuki Clan, and the tag team partner to the Sixth Raikage. Formerly a general of Darui & C in Kumo's Civil War, he was assigned to a four man team that led the First Division. His teammates were Yoru, his late childhood friend and an Uchiha Prodigy, & the jinchūriki of, Mamoru, along with the previous war hero, who led them all.

A master of Lightning Release himself, his affinity, he sought to earn fame his own way, deciding to do it by mastering the greatest lightning jutsu of all time. Through many of Kumo's best, he was able to achieve this, with his hard work, effort, time and persistence. He has managed expanded on each greatly, unlike any Kumogakure shinobi ever before. Now one of Kumo's greatest rising shinobi just like his teammates, he is an adept avatar of the electric art. So adept, he has even mastered the powers of natural lightning, becoming known as the Electro Bringer, for his prowess as an avatar of electricity and lightning.

Now prominent in the ranks of the Cloud, following in his father's footsteps, he serves as Mamoru's right hand man, as well as partner in battle. Under his leadership, the Cloud's ANBU has prospered. He has brought in new advantages, and tactics for the Cloud's Black Ops. With him in command, the Golden Horn Force has been started anew, and is way more powerful than ever before. Kei also serves as an ambassador at times, for the Lightning, helping with his village's & country's international affairs, and overall, doing his best for the places he calls home, Kumogakure and the Lightning Country.

Early Life
The Land of the Lightning was probably the worst off in the aftermath of a. Plagued by natural disasters, it made living life in that country almost a living hell. But the people of the Land of Lightning were tough, brave, prideful. Some even called them arrogant. But no, truly they are just proud people, loyal to their home until the very end.

This is where the story of Kei begins. The son of the renowned, bodyguard to , he was born during a time of strife for the Lightning Country. When most wouldn't recommend having a child. But C, the-ever-loyal Hidden Cloud shinobi, did. It was to help the Lightning Country, who had begun to fall short of great shinobi after the war. Ones of amazing caliber had died in the war, or were stuck rebuilding what could in the Lightning. Terrorized every day by the memories of their fallen comrades. This experience made C realize he was mortal, and could die any day. Upon returning to his home, he quickly went back to his dark-skinned fiancee, and soon fathered a child by her. This child, would come to be named Kei.

Kei grew up under the care of his mother; as his father was soon called by his friend Darui to take care of the son of Killer B. So at first, Kei came to loathe his father at times, as he barely got to see him. He spent most of his time protecting Mamoru, from those who might hurt him. However, as he grew, he came to respect him, as he was doing what he needed for the village. This was explained to him by his mother, who was his teacher in his early years. This led to Kei being one of the few to know of Mamoru’s existence, and who he truly was at such an early stage of the jinchūriki’s life. Of course, he couldn’t make sense of it at the time.

Kei’s early life was also pestered by constant storms, as a result of the natural energy overload in Lightning Country. He never really had a single home. It was only a matter of time with each house he lived in before he had to move yet again. However wherever he was, he felt at home, under his mother’s care.

It was under that care, and C’s recommendation, more of urging, that brought Kei to the academy. His mother helped him through his studies, and by his own work ethic, Kei began to train on his own, honing his body in order to keep up with the academy’s tests. Kumogakure’s Academy does have a lot of physical work in it. This allowed him to excel in the Academy during his stay.

As Mamoru had begun to stay at the academy as well now, Kei got to spend more time with his father. This allowed for them to bond at least for a short time. He influenced Kei, and Kei became determined to help Kumogakure however he could. He also helped Kei discover his lightning affinity. This can be traced as the source as Kei’s repeated dedication to his studies and to his training. He bonded with his mother during study, and his dad during training, become a powerful and smart child. He made a bunch of friends, including Enkyo, a fellow clansmen, who he helped out with his expertise.

In the academy, Kei begun to see Mamoru up close and even befriended him. The day Mamoru’s secret was out; he had even forgotten what his parents had told him about him. He really began to question if Mamoru was capable of what they said, the people of Kumogakure. As the graduation exams drew nearer, more and more did the Land of the Lightning’s people oppose to Mamoru’s staying in the academy. So he was taken out. Kei soon had to study and focus on graduating, and with Mamoru’s withdrawal, soon Kei’s time with his father became less and less.

However, he was thankful for the time he had with him, as he had taught him many things. With this, he was able to pass Kumogakure’s academy graduation exams with ease. He was soon put onto a genin team, where he would be pushed to his very limits.

Pushing Himself, A New Team
Team Omoi.

Assigned to a team under the care of the master jonin, Omoi, Kei’s training as a genin started off with a bang. Omoi, a hero from the war against Gods, was a tough teacher, pushing the genin to their limits physically at first, everyday, as it was the norm for Kumogakure to have physical pushing tests.

After tests of the body, Omoi began to teach them. Of ninjutsu, of genjutsu, of improving taijutsu. This is where Kei began to learn and become comfortable with the basics of shinobi combat. Progressing well enough, he was not the best of the best; the title belonging to one of his teammates, a prodigy.

Kei met his first rival, Yoru Uchiha while on this team. The child in question was indeed a member of the famed Uchiha Clan, and as a result, was a true prodigy, graduating from the academy a year younger than Kei.

Yoru already showed tremendous progress as a ninja, with some skill already shown in the Fire Release. As an Uchiha, he was truly just well-rounded shinobi, even for a genin. He was easily above Kei and the other genin of the team. Whenever the team went on missions, Yoru was in the lead out of the trio, and soon, it looked like he’d be recommended to the exams, at least to Kei. Team Omoi became known for Yoru only, the other two in his shadow.

Kei sought to change this. Asking for private lessons under his sensei, he would be trained in the art of the sword, and his lightning nature, for the next two years. This is where Kei learned the Cloud Style basics, from the sword master, who gave him his first sword. Omoi also helped Kei master some basic lightning techniques, including the Thunderbolt and the Stream.

For two years, Kei, Yoru and the other genin trained under the legendary war hero Omoi, who helped them become skilled, for genin at least. Wanting them to all go to the exams at once, he didn’t send them the first year after their graduation, due to Kei and the other genin not being ready yet. A year later, he then took them all there after Darui, the Fifth Raikage’s approval, as he was sure then that all would pass. At the age of 12, Kei and his Team set out from Kumogakure in sight of the Land of Iron, as it was where the exams were being held that year, 12 years after the Fourth Great Shinobi War.

Chūnin Exams
The cold, unforgiving Iron Country.

Laden in white, wherever Team Omoi went was covered with snow and ice. A trademark of the home of the samurai. Ever since the Fourth War, the Land of Iron had begun to mingle with the shinobi lands. The shinobi managed to grow on them per se, and the samurai and shinobi began to coexist together. The Land of Iron was thus brought into the rotation for the exams, and by the time Kei was entering, it was their time to organize the exams.

But this also meant a more physically demanding exam for the Kumogakure ninja, a more grueling one. The samurai are a people who learn by doing, who give trust and respect based on action. So it was obvious that an exam hosted by them would test the body physically, and the mind on the field of battle and survival.

After Team Omoi arrived in the Country, they settled into huts at the edge of the border, not comfortable at all. However, the best of warriors need to work hard, even in the least favorable conditions.

The first test? Sword proficiency. Early in the morning, the genin were aroused and gathered. Kei being among them of course, they were each given a set of two wooden swords, used for the first part of the exams. These involved sparing one to one, with these swords alone. Pairs were made, and Kei soon found himself up against a huge Iwagakure genin, one of massive strength. Nervous at first, he soon put aside his fear when given a speech by Yoru, inspiring him to try his best for Kumogakure and the Lightning Country.

Doing just that, he stepped onto the arena, where the pairs faced off. A ring of sorts, it was more of a boxing ring than anything else; closed off, with an audience all around, and a proctor samurai up above, announcing the start.

As the battle begun, the Rock’s genin came out swinging. It was Kei could do to block the huge guy’s swipes at his face. As this sword fight continued, it was easily seen that Kei wouldn’t prevail as long as he continued to stay on the defensive. And as some strikes of the Iwagakure genin began to get past his defenses and actually hit the Kumogakure ninja, it was clear Kei needed a change of strategy. And soon. So Kei got to thinking, as he analyzed the movements of the shinobi. Kumogakure’s Academy had not only taught him physical domination; for what if your opponent is just stronger than you? You analyze their fighting style, and use their weak points as places to hit with your own physical strength.

Doing just that, Kei realized that between strikes, the genin’s neck was open. So, instead of blocking the next strike that came towards him, he dodged and rolled closer to the genin. Getting up, as he had surprised the genin by getting behind his defenses so easily, he swiftly struck the neck of his opponent with his wooden sword, taking him down and winning the match. The neck is usually a weak spot.

Congratulated by shinobi and samurai alike for his victory, it was noted by the samurai proctors that he was a potential candidate for becoming a chunin. However, even among all this good cheer, he was still stared at with vengeful looks by the Iwagakure genin’s teammates. Disregarding them at the time, he went to celebrate with Omoi, Yoru, and U (ユー, Yuu), his last teammate. Yoru and U had passed as well, with the former doing it through sheer skill, and the latter more thinking on his feet, like Kei did.

The first test continued till the end of the first day. With the day’s conclusion, it was shown which of those had moved on. In the dire times, not a lot of participants had formed this year, leading to only 60 genin at the start of the exam, and at the end of the first, half had moved on, the half that won their duels. This left the winning 30 to face the second and third trials.

The second trial was simple in a way. At the start of the second day, the 30 succeeding candidates had been transported to the Three Wolves, at the base. The task? The genin had a week to survive and climb to the top of the three mountains. Reaching one of four points would signify success; the center peak of the three, or if it came down to it, the peaks of any of the three mountains that made up the Three Wolves. There would be units of samurai set up here, in huts, ready to welcome the winners. The winners would then be taken to the central location, where the finals would begin sometime afterwards. However, there was a condition. Even though the climb of the mountains would be hard enough, especially in a week for the genin, it was also made so that only six teams (or only 18 genin) that had gathered at the base could advance. As soon as 18 had made it to one for the four checkpoints, everyone else would be eliminated; this forced getting to the checkpoints as quick as possible, a priority.

So as soon as the exam started, Team Omoi went straight to work scaling the mountains. The going was tough, and it was all they could do to keep their focus in the cold, and use their chakra to stay attached to the surface of the mountains. Within the first day, they barely made progress up the mountain, but thankfully hadn’t seen any opposing teams. Other candidates could serve as obstacles on this exam; they were also things to overcome, as they may try to sabotage your chances of getting up to the top- to lower down the competition so to speak.

Without seeing anyone the first day, the team had gotten the hang of their adhesive chakra technique basics, in order to do it without consciously focusing on it. This also allowed them to hunt for the little game on the mountain, and collect mountain grass without opposition. This allowed them to survive the first day.

With the second day, now relaxed, with vigor, Team Omoi attempted climbing again. Making progress, this day was much different from the first. Around noon, they came around another camped team; a group of Sunagakure shinobi, not really adjusting to the cold. Team Omoi was lucky to have Yoru on their squad, with his heating capabilities. Kei was not willing at first to take out this team, but Yoru insisted it would be effective in progressing. They stalked around the Sand shinobi, awaiting a time to sneak up on them, and disable the whole team. However, this chance never happened. Sunagakure shinobi were not stupid. They had tricked the Team Omoi into gathering, using a mirage like genjutsu, much like mirages in the desert. But here, it was a mirage in the tundra instead. By falling for this genjutsu, Team Omoi had fallen straight into the Suna trap.

The Sunagakure shinobi attacked from behind and only Yoru had snapped out of the mirage genjutsu fast enough, realizing it was one through his Sharingan. He managed to hold them back, as he aroused Kei and U from it as well with the commotion. With the whole team disgruntled, but on the offensive, the Kumogakure shinobi faced off against the Sunagakure shinobi. As Yoru used heat to control the battlefield, so his friends had places easier to use chakra to “stick” to, U used his bukijutsu mastery to drive the Sunagakure shinobi back. Kei finished them off with a Lightning Release Stream, literally blasting the opposing team down the mountain.

Successful in taking down a team, or at least, slowing them down, Team Omoi raided the team’s camp, taking essentials and then proceeding up the mountains again. As the second day came to a close, bells had sounded. This confused the Kumogakure shinobi at first at their camp, but then U remembered something the proctor had said. Bell ringing signifies the arrival of a team. Once this had happened six times, (usually), it’d mean game over for the other teams as 18 would’ve arrived by then. Of course, if individuals had arrived, they’d send off a different bell sign. But this was definitely the sign the first team had arrived at one of the checkpoints. Astounded, Team Omoi realized had little time they might have till 15 more arrived, and it would be game over for them. They resolved that within three more days, they should get up to the checkpoint at the center of the mountains.

However, this plan was somewhat stalled. With the addition of the third day, a blizzard soon hit. While not severe, it still chilled the genin, and it was all they could do to keep warm. This delayed progress, and so did another encounter with another rival team. This encounter led to Kei being separated from the group.

As he wandered in the cold, he soon realized he was hungry, and tried to hunt down a goat. This was one of the first times he had done this alone, hunting. Usually Yoru did this for them, as Kei’s only hunting experience had been with his father. But Kei, being alone, needed food. So he’d have to do this on his own.

Managing to track down a goat, he only scared it off as he approached, forcing him to chase after it. He managed to get his act together though, and carefully and quietly stalk it down, killing it with his sword, and lightning release chakra flowing through it.

He cooked it best he could; using the heat generated from his lightning and ate. As he ate, he would be found by his other teammates, and his makeshift hut he had constructed out of rocks, and a mini-cave, to keep warm in the cold. In the blizzard, warmth was detected a mile away, joked Yoru as they walked in on him. The team made camp in the cave that day, with barely any progress, sadly, as Kei getting lost and the blizzard hindered them. They still resolved to get to a checkpoint soon however. They could all attest to that. They made a pack that night, they’d they make it to a checkpoint in time. Even with whatever the mountains threw at them.

So with the fourth day, Team Omoi got serious. They only focused on getting closer to the top, only stopped for minor rest breaks, and once for a full meal. This proved very effective, as the blizzard had settled down, and they didn’t encounter any of the other teams that day, though two more and three independent individuals also arrived at a check point during that day. This left only two more sets of three, before game over.

But Team Omoi was getting there. And with the fifth day, afternoon time wise, they could even see the checkpoint in the center of the mountains. They had made it, mostly…

As they neared, they encountered another enemy team, just as another bell rung. Which meant only one team could pass on. This meant an all out brawl between Team Omoi, and the band of Sunagakure genin they had encountered early in the phase. This brawl did in fact occur, but the Sunagakure shinobi were smarter than before. They were beginning to win the tide of this battle, and soon, Team Omoi would’ve been overcome by this band of three Sand shinobi. However, Kei wasn’t about to let this go down, as he and his team had come so far. They weren’t about to just lose to a group they had already beaten.

Recalling a technique that his father had used on several occasions during hunting, Kei made the Ram, Horse, Snake and Tiger hand seals, to execute an advanced genjutsu, the Lightning Illusion Flash of Lightning Pillar. Determined, he succeeded in using the flash of light to blind the Sunagakure shinobi, for an even longer period of time, using the snow to reflect the flash’s brightness. This also worked on his teammates as well, though not as much as it did on the enemy- a side-effect of not mastering the jutsu.

But still, it proved as a good enough distraction for Kei to half-pull, and half-lead U and Yoru to the checkpoint, and outright beat the Sunagakure team there. A final bell sounded, and a game over notice boomed across the mountain for any of the remaining teams. Soon, as it was told to the Team, that helicopters would swoop in and collect those who’d had yet to make it, saving them from the cold.

As for Kei and the rest of his team though, they had succeeded in making it to the final phase, as told to them in the central hut. They were rounded up, along with some individuals who had made it to the final phase as well, to be taking to the more centralized location in the Three Wolves Mountain, where the final phase would be held- a tournament. But not one limited to wooden swords, and physical strength…

As they gathered in the more central location, they were shown to dorms, and told that within a week, the final exam would start. A tournament, not unlike those of the Chunin Exams soon in the series, but done in this centralized arena, which was down below in the building. A week for all the village leaders judging to arrive and a week for the candidates that had passed to this stage, to rest and prepare as much as they could; to be judged, and see which of the 18 had the aptitude to become chunin. With this in mind, Kei spent the next week in the place honing his skills, with the personal help of Omoi. He had been the only one who had requested their sensei’s help. (Note, all the jonin teachers of the succeeding genin had been gathered at the central location, before the winning genin had arrived themselves). With the help of Omoi, he had begun to get the hang of his lightning genjutsu, and honed his kenjutsu skill somewhat more.

Seven days past more quickly than Kei had expected. On the day of, the remaining 18 were gathered. The four individuals, one among them being Kakezan, a promising Frost Country candidate, a Konoha Team, Team Sakura, including Hayazumo, and the Iwagakure Team was amongst them, along with 8 others, two more individuals and two Teams, one from Sunagakure (two teams had gone from there), and one from Otogakure. The tournament was soon to begin, at noon that very day. Each genin was given a chart, with who’d they have to face throughout the tournament. Yoru and Hayazumo were facing off first, followed by Kei and a Sunagakure ninja, and U and an Iwagakure ninja. And so on, and so on.

The genin were escorted down the building’s levels, to the arena where the judging leaders had gathered in the stands. To the sides resided the places where the genin would wait for their battles. In the center was a battlefield. Plain of sorts made of metallic ground, with pipes interlocking above, not much different from the past appearance of a building of the Hidden Rain.

For the first battle, Yoru and Hayazumo were to face off. Hayazumo’s team, Team Sakura had been the first team to reach a checkpoint, the one that succeeded within two days. So it was safe to assume that Hayazumo was strong. However, Kei believed Yoru could take him anyway.

However, he was somewhat wrong. He watched as Hayazumo’s innovation skill soon overcame Yoru’s skill. Hayazumo actually managed to pull off a standstill against the two, using his quick thinking. To combat Yoru’s fire, he slashed the pipes above to drop down water, etc. This ended in the eventually tie between the two. This shocked Kei, as he had previously thought the Uchiha’s power couldn’t be matched. With that battle’s conclusion, came Kei’s with the Sunagakure genin. This one possessed the Wind affinity, a perfect foil for Kei. As his powers insulated Kei’s lightning, he was forced to attempt getting close to the Suna Genin. But obviously, it was difficult as gusts of wind were generated to hold Kei back. He’d need a new idea if he was going to prevail against this shinobi.

Using kunai, and his sword as distractions, he threw them at the shinobi. This preoccupied him, as he attempted to blow them away. This left Kei able to use his Lightning Pillar effectively on the genin, binding the guy long enough for Kei to charge Lightning Release: Thunderbolt. As he fired, the Sunagakure shinobi tried to recreate a shield of wind, as he begun to gain back his sight, he was too late as the amount of wind’s insulation was not enough against the high frequency used to create the Thunderbolt technique. The Sunagakure genin hadn’t enough time to mount a proper defense, so the attack blasted through the wind, and ended in a swift defeat for the Sunagakure ninja, and victory for Kei Yotsuki.

Cheers erupted from the crowds, as Kei was able to come out on top. Kei retreated back to where the genin had gathered, to continue watching the battles. Kei witnessed as his teammate U was pitted against an Iwagakure genin. U had been training with Yoru; his bukijutsu specialty had become enhanced with chakra. But even this wasn’t enough against the aspiring Earth master of a genin, and his brute strength. The Iwagakure genin managed to defeat U with some ease it seemed.

While this didn’t trouble Kei, though he was saddened that U had tried his hardest and lost, the Iwagakure genin insulted U where he lay. The Rock was still angered by their earlier loss to the Cloud it seemed. But insulting a man who had gave it his all in battle was not okay to Kei. He swore to make him pay.

His chance soon came, in the second rounds. After the first round, one of the participants, Kakezan, had been promoted to chunin instantly, for his incredible talent, skill and thinking capability. This left eight, to finish out the tournament. While Kei was able to defeat the Iwagakure genin in his battle, using the power of his lightning over earth, Kei was still eventually eliminated both the end of the tournament. The winner of the tournament wasn’t really well-known, and whoever it was, it didn’t matter to Kei.

After the tournament, within 4 hours, the results of who had made it had been posted. Kei, Yoru, and U were amongst them, much to the latter two’s surprised. Kei was elated; it was the newest step into becoming the best he could be.

After the results and the next few days of recovery from the battles, Kei and his team were leaving the borders of the Iron. But before they could leave they were approached by the Iwagakure jonin, who had taught the genin team that the team had gotten into altercations with. The Iwagakure woman wanted to talk, to Kei out of all of them. She had a proposal, she had said, as she had taken “interest” in him.

At first Kei was wary, but Omoi urged him to talk with the jonin. The Exams are all about improving relations with the other countries. So Kei heard the Iwagakure kunoichi out, and she surprised him with an offer to visit the Land of Earth! Her genin had respected him, and looked at him somewhat as a rival now. They had personally made her asked if he’d go with them to their homeland, to train alongside, and become stronger together, for an unspecified amount of time.

Kei told Omoi, and after mulling it over, he allowed Kei to go. Though some Cloud shinobi would be sent to supervise, Kei would be allowed to go to the Earth Country, for training, and improving the relations between the Lightning and the Earth. So Kei said his goodbyes, and he departed a different way with the Iwagakure shinobi to go to the Land of Earth, where he’d stay for three and a half years at least.

Pursuing Lightning & Further Training
Arriving in Earth country, it took no time at all for Kei to get used to his surroundings. The Land of the Earth had more cliffs and rocky structures than the Lightning, but still, it didn’t take long for Kei to feel at home. The people of the Earth quickly warmed to Kei, as he showed a sign of hope to them, though he didn’t know it at the time. Kei meant to them that there was hope in at least one village, Kumo, siding with their Fourth, in their times of isolation from the other Great Nations, in terms of their “problems”.

But Kei was of course oblivious to this picture, as being a genin at the time; he was not involved in the world’s politics. And no Earth person cared to really detail it to him. So instead, Kei’s focus was on training, and honing his skills, with his Iwagakure genin comrades, who had become chunin as well.

Kei’s training consisted of a lot of rock climbing, scaling cliffs to strength his body. This improved his upper body strength, while a ton of other activities raised the strength of his legs and overall his whole body. His endurance went up, and basically over the years, Kei grew into a teenager of peak physical condition, better condition than most other shinobi. This led to the start of his yang-natured chakra increasing. As he developed the body, he gained more yang energy. However, he never managed to incorporate the energy, until sometime later in his life.

Regardless, Kei still trained his body, to gain a high durability as well. As he had training battles with the huge genin, and other men of Iwa, his physical tolerance grew, and so did his body’s resistance to physical force. This resulted in the type of body the Raikages possess. Kei’s body became hard, and defensive, capable of travelling at the speed of light, without injury.

The training with the Iwagakure genin was all in all, very physically demanding. It led to Kei being able to face men of great size and stature, or users of the first few gates, with his taijutsu alone and prove to be effective against them. It pushed his body to its physical extreme, something he maintains even to the current day. His taijutsu took on the Strong Fist style, his blows and strikes easily being more powerful than the hits of others. This also gave Kei a high physical tolerance, one he has since then trained to become somewhat supernatural, being able to stand up to the first three of the Eight Gates with no problem, in terms of dealing with the damage, which is usually non-existent, due to his high durability levels. During this time, he also improved on his kenjutsu skills, a secondary thing, coupled with his physical training.

In addition to taijutsu, and a powerful and quick body, while in Iwagakure, Kei began to pursue his lightning affinity even more. With information and training from the few Kumogakure shinobi supervising him, and the Earth country people about lightning and lightning release, he began to study the aspects of lightning, refining his old lightning techniques, and inventing new ones. This is where he perfected the basics of using lightning-natured chakra, and its chakra flow. This is also noted to be the time; he invented the Cloud-Style Electric Beheading, along with what he calls now the basic uses of the Pseudo Lightning Release Armor he invented- the shocking touch, made from coursing lightning chakra throughout the body. During this time, he learned of the greatest lightning techniques, and gained the desire to master them, especially the ones invented by Kumogakure shinobi, such as the Lightning Release Armor, and the Hell Stab. The Pseudo Lightning Release Armor was created, and thought to be mastered at this time, along with its basic uses, as one of his attempts to recreate the Lightning Armor himself.

With this tremendous progress in the skills of Kei over three years, he would soon have to leave Iwagakure, as the city turned to turmoil. The Fourth Tsuchikage’s rule had begun to get opposed, and the people of Iwagakure showed signs of rebellion. The rebellion wasn’t in full swing yet, but the Cloud shinobi with Kei could notice the signs of the civil war in Iwagakure and the Land of Earth growing. Notifying Darui, he requested for Kei and the others to return, and as such, Kei was forced to say goodbye to his Iwagakure friends. Just 16 now, Kei would return to a Kumogakure he hadn’t known before in his whole life of almost two decades.

Kei’s friend, Mamoru, had returned to Kumogakure.

Warning Signs
Before Kei had departed for the exams, Mamoru was on the Island Turtle, taken there under orders from the Raikage himself to master Gyuki, and for his own protection. But now, Mamoru had returned, and Kumogakure was in some disarray, being forced to accept Mamoru due to Darui, their leader. One of the reasons Darui had called Kei back was to help with this situation, as the shinobi did not think it was wise to keep various shinobi out in different lands, when he feared their own would become somewhat unstable as well. And sadly, he would be right in time.

But in the meantime, after being welcomed back by friends and family, Kei began to spend time with Mamoru, along with Yoru, U and only a few others of his friends. Mamoru would be thankful for this friendship, and would eventually play a part in helping Kei’s dream. Mamoru would be the one to convince A in his old, retired age, to teach Kei Lightning Release Armor. Though Kei couldn’t get the handle on it at the time, he was very grateful to his friend for assisting him in his effort to learn all lightning techniques.

Kei and the few others proved to be some of Mamoru’s true friends, besides his tailed beast and Darui and the elite. As the friends trained and lived together, they would start to become close, and form true relationships. It would be because of this that the citizens of the Land of Lightning, well at least some of them, would begin to warm towards Mamoru.

With Mamoru’s return, bandit legions began to grow in opposition, wanting the jinchuriki’s head for something he did in his past. At times, Kei would be the only friend around to help Mamoru deal with this, all weighing on his head. And soon, over two years, the bandits would grow enough to form an army, preparing to invade Kumogakure unless the jinchuuriki surrendered to them. Kei would help his father, Darui and his friends in persuading the people of Kumogakure that this shouldn’t happen. As such, within months, Kumogakure rallied behind the jinchuuriki, and refused the bandit demands. Darui would gather the people to protect Mamoru, and Kei would be one of those in the forefront of this, now 18. As they prepared to defeat the bandits and stop their plans, Mamoru would halt these efforts, telling the defensive groups only to watch as he took the burden on himself to defeat the hundreds of bandits which had then gathered at Kumogakure’s gates, demanding the Gyuki host.

Kei of course, was one of those greatly opposed to this, as he wanted to protect his friend personally. However, on Darui’s command, he stood down, with the reassurance that he along with the defensive force would be watching closely, ready to step in if needed. Kei didn’t completely agree, but in Kumogakure, it was natural to let the one who caused the problem, fix it if they take it upon themselves to do so.

And fix the problem, Mamoru did; at least, somewhat…

In an altercation that would become known as the ‘’’Battle of the Titan’’’, Mamoru would summon legions of ink creatures from his scroll using the monstrous chakra of the Ox. These ink creatures, along with Mamoru himself, would kill every single bandit, and rogue, except one survivor of the whole thing. Kei was taken aback by Mamoru’s power, along with some of his friends as well. Kei was powerful in his own right, but taking on hundreds of people, some of which were minor shinobi? Something like that was almost unimaginable for Kei at the time.

Kei and his friends were best off though, meaning they reacted the best to this. Sure Kumogakure was free from the bandits yet again, but what of Mamoru? Many of the people who had witnessed Mamoru’s massacre began to question the jinchuuriki, and his stability. Was he even fit to be a jinchuuriki, with that ruthless nature of his? As more and more shinobi would come to fear and question the master jinchuuriki, the single survivor of the massacre also began stirring the people of the Land of Lightning to the “Anti-Mamoru” side. As these sides were drawn, they would soon escalate to war sides. Those who supported Darui and Mamoru, and those who wanted to see a newer, more capable jinchuuriki and the fall of Darui, who supported such a “monster” in their eyes. Kei of course, knew his friend well, and knew he wasn’t a monster. But even though Kei, his friends, Darui, C and the others tried to convince them of this, it was all in vain. The seeds of doubt had grown, and the roots unmovable. The single survivor had basically sealed the deal, crafting a side of the Land of Lightning and Kumogakure that would not rest till Mamoru was dead. This would cause a short period of civil war over the jinchuuriki of the Cloud. However, while short, it would be nothing to scoff at. Darui realizing this pulled those on his side, those in the shinobi force of course, into mandatory training to prepare for the inevitable war.

Kei, now 19, would begin to prepare for war, something he had escaped years before in the Earth Country.

Nearing Warfare & the Start
As Kumogakure grew divided, many assassination attempts on Mamoru began again, and while Darui and his tag team partner C tried to quell these, the conspirators, eventually fled the village, to join the growing opposing faction. As such, Darui would then call for the mandatory training, as those still on his side prepped for war.

Kei would find himself training with the elites of the village themselves, among Mamoru, Yoru, U, C, Darui, Omoi, Karui and a few other famed Kumogakure shinobi, still on the side of Darui. This would be because of C’s personal recommendation for his son to receive the best training possible before the war. It would be because of this that C would teach Kei the Mystical Palm Technique during this period. A way to help those he would be leading; as he was training with the elites, he’d definitely have a leading role in the times to come. He also perfected Lightning Release Armor within this time and its derived techniques (as A would help him from time to time during training), along with other lightning techniques, such as Lightning Shower, Lightning Strike, Lightning Weaving among others. He would spend the time mostly refining his lightning techniques, and perfecting his chakra control, which would eventually allow him to master the medical ninjutsu his father taught him. He also had some time to practice hand to hand combat, and bukijutsu with U, among refining other techniques.

Darui would also personally train Kei during this time, and teach him how to use Black Lightning, a highly yin-based technique. As Kei was a more active Lightning Release master, Darui would teach him as a way to make sure the legacy of the black lightning would be properly upheld; Kei would use it more often than Darui did. It would also help the force, if there were two users of the midnight colored lightning. So during this time, Kei worked on his spiritual energy increasing training with Darui, which included a lot of meditation, reading to expand his knowledge (usually on the principles of lightning) and daydreaming. This would eventually pay off, and shortly before the war’s start, he tamed the powers of Black Lightning as well, truly becoming one of Darui’s successors of the legendary lightning.

Shortly before the war, Kei would develop White Lightning, based on his high physical energy, using the concept of black lightning being highly yin based- white lightning would be highly yang based. However, he didn’t get to master it, before the act that would cause the declaration of war.

It would be the death of an important figure that would start it all. One that Darui had taken extra precautions to keep safe as well…

A.

The legendary Fourth Raikage would be killed at the dead of night one day, due to the attack of a rebellious Kaguya, and a certain Uchiha involved in the Blood Bound Apostle, a movement in Kiri. However, Kumogakure did not know this, and Darui instead made the connection of A’s assassination to the rebelling faction. A ploy for them to weaken Mamoru and the forces for him, as they lost an important figure in a symbolic sense, and in a quite real sense, as the retired Raikage was close to a number of those in the pro-Mamoru forces, including Kei (through the years of learning and mastering Lightning Release Armor under him).

The true killers of A entered & escaped in the night, and with no evidence against another cause, as there were no survivors among the guards who were protecting A, Darui had no other reason to assume any other cause of death for the late Raikage. Because of this, he officially declared war on the rebelling faction and deployed forces to find their base, and end them once and for all. According to him, in his inspiring speech send-off to varying divisions, “People who’d stoop low enough to take away an important village elder don’t deserve to live.” Kei would stand by this, and would grow eager to get on the battlefield, as they began to engage the enemy, getting closer and closer to the enemy base.

His chance soon came, as soon as the war started, Darui and C gathered him, Mamoru, Yoru, U, Karui and Omoi in the Raikage Office- the pro-Mamoru HQ, and delegated them to be leaders of the First Division.

Kei was ready for this. For the village of Kumogakure, for A, and for his dear friend Mamoru, he’d enter the war. Given three days to prepare, Kei along with his partners in leadership gathered the large First Division of many Kumogakure and Lightning Shinobi, to deploy them into the fray that was unfolding about the Land of Lightning. Darui’s forces were hoping to end this as soon as possible, by finding and destroying the enemy base. As such, the First Division would split up into two, with three leading each half. Omoi, Karui and U would lead one, while Mamoru, Kei and Yoru would lead the other. These regiments would deploy in different directions to engage the enemy, and attempt to find the enemy base, which they did immediately after splitting. Kei’s group soon met their first enemy band of soldiers.

For Kei, the war had officially begun.

Civil War
Yoru would grow into a natural leader, leading the trio through everything. For this one battle, they had assembled on cliffs, over-looking the opposition. Yoru begun to speak, to his partners and the army behind them, before they entered into battle. Inspiring to say the least, the Uchiha instilled hope into the hearts of the Kumogakure men and women. United as one, and hopeful for victory, their half of the First Division engaged into battle, the trio in the lead.

Kei, clad in his Lightning Release Armor, would come to be known as the fastest man in that division, as he utilized it to lay waste to the battlefield with lightning-related techniques, in mere moments. Only Yoru was quicker, employing the Flying Thunder God technique he had learned sometime after the exams, searing the enemy with his white flames. Of course, Mamoru also was there, using his ink creations en masse, with Gyuki’s chakra reserves as the massive fuel. Together, along with the help of the division, the enemy army was no match for the hopeful group. They won that day, their spirits ignited hotter than the flames of Yoru.

For more than a week this continued. The famed trio would lead their forces day after day, and at night, Kei would assist in healing the wounded. Their half would make great progress, in the pursuit of finding the capitol. One day, a survivor of the battle from the enemy side was captured, and interrogated by Mamoru. The jinchuriki was able to get him to cough up the location of the Capital, the enemy’s base. Located far north in the Lightning, where the cold was a natural defense. The prisoner was killed soon afterwards, and the trio continued to lead their army towards victory. HQ was signaled by Kei, using his Lightning Release: Lightning Signal Fire, along with their communication chains. This allowed for C and Darui to get the other divisions, and the other half of the First Division to regroup and follow Yoru, Kei and Mamoru, on their path to the base.

However, not all on this path would be good, as the enemy had begun to attempt to divide and conquer the army. Though the army managed the regroup and move towards the capital, they still weren’t completely safe. On the fifteenth day, the army, large as it was, would find itself in trouble against the enemy. The enemy, desperate to keep the opposing force away from the Capital, used bombers to attack the forces. Dropping bombs, shinobi of the Explosion Release, kamikaze-diving like planes, etc. These explosions decimated the forces of Darui greatly, and caused mass causalities to the forces as well. This would eventually cause C to come to the scene, after the attack and carnage had ceased, with the force of Darui retreating. Father and son would reunite, and help in healing and moving soldiers away from the battlefield, to regroup and such. However, the rebels in secret were not done, and dropped one last bomb on the unsuspecting Kumogakure forces.

C sensed the bomb before Kei, and violently pushed Kei out of the way, saving only his son and not him. Kei could only scream before his father, the legendary C, was blown up, in the massive explosion that followed. C had managed to get him out of the range, but only barely, as he himself had been trapped within the blast radius.

Kei would grieve for his father, who would eventually be regarded as a hero of war, healing those in need and saving his son at the very end. With the death of his close friend and partner, Darui personally ordered a four-day break before continuing to advance. Kei would spend those four days mourning for his father, his idol in life. But in this time of war, Kei would accept that he died for his village, and for his son. He would resolve to protect the village and what was important, and what else he deemed important, like his friends. C’s death strengthened Kei’s resolve for Kumogakure and would bring about Kei’s mastery of White Lightning with the days that followed as he attacked the enemy forces with renewed vigor after the break, avenging his father. He would bring out the more vitalized electricity in order to burn his victims alive in his anger, and as a result, he would on accident learn how to fully execute the powerful, hot and intense electricity of the technique he invented. With the help of Kei and the others, with Darui leading the way, they would find their way to the Capital on the twenty-fifth day, with the help of Yoru teleporting the remaining army the rest of the way there.

Forcing the enemy to go on the retreat again, into the Capital, the forces of Darui faced one more obstacle, the wall.

Almost impenetrable, the Capital in the north was surrounded by a huge wall, made of materials such as steel and diamond, and infused with chakra to become extra hard and almost impossible to break. Even with the sheer scale of people the Kumogakure forces had, they still could not get through the walls.

Thus began the three day siege, as the forces attempted aerial assaults of the wall, as in attacking up into the sky, and hoping to take out the guards at the top of the wall, and cause damage within. Kei himself would take apart in this attack, clad in his Lightning Release Armor, shooting the Lightning Gun Technique into the sky multiple times, to assist in the attack. However, this would be tiring and go on for days, before thunder clouds had begun to form, from the heat in the atmosphere left from Kei’s many, many lightning bolts into the sky, before they came down on the enemy. As the storm grew, it became dangerous to be out in the open attacking the gate, as lightning strikes became frequent around them. Taking cover, the division was forced to sparingly attack the walls, to avoid getting fully blasted by a bolt of lightning, or blown away by the wind, or pelted by the rain. However, even in the dangerous storm, even in the cold, Kei saw his chance to be great. With all the lightning strikes, he began to muse if he could tame the lightning, and use it to destroy the wall. A wild gamble, but it could work. And with Kei’s prowess in the lightning, it was not impossible, or improbable. So he gave it a shot; to help Kumogakure into the final phase of the war, and for himself, for the prestige of lightning mastery.

Kei run out from cover, despite what others yelled, to where a bolt of lightning was to strike. In the heat of the moment, and on a half baked idea, he focused Lightning Release chakra around his right hand, which he lifted into the sky. A concentrated part of his Lightning Armor, he hoped the focused chakra would be able to direct the strike. As the lightning struck, he had no time to readjust his hand, and Kei braced himself for the deed he was about to do. All he had to do was direct its flow, towards the wall…

This is exactly what he did. The focused chakra around his hand acting like a Chidori, it allowed him to almost flawlessly direct the lightning bolt at the wall, as he discharged the focused blast at the wall, with the lightning bolt, at full force. Suffering minor burns for his not perfect execution, with his perfect chakra control and expertise with lightning current, he managed to do it well enough. And thus, Kei utilized Kirin that day, blowing apart the wall at the seams, and gaining them entrance to the city, the enemy base. Kei would come to be known as the Electro Bringer for this, as he tamed natural lightning and used it to his advantage. This would make him legendary, in terms of the Lightning Release.

Omoi, along with Kei, Yoru and Mamoru led the way through the enemy base, after Kei broke through the defenses. Directed by Darui through communications, they travelled on the main street, and managed to get to the center in record time, to destroy the leader orchestrating the whole rebel faction.

Expecting an easy kill among the four of them, as they entered the building, the four were shocked at what they found.

The leader, a member of the extinct Tsuchigumo clan (土蜘蛛一族, Tsuchigumo Ichizoku), was shirtless, baring a seal on his back. He had organized a barrier, he told them, which prevented the use of ninjutsu within the walls, well creating new chakra, except for his. He would unleash Fury on the whole city, in a last ditch effort to kill the jinchuuriki once and for all, along with vaporizing the city entirely. Team Omoi quickly turned tail and ran out of the building, and warned the masses, only to find a blockade the way they came, of various objects, and the remaining rebels, dedicated to the cause.

So the Darui forced had only one option, which was totally unpractical; escape via climbing the walls, as attacking the blockade head on would take far too long. But climbing would take just as long, and they were running out of time. But in order to save the most people possible, Yoru devised an idea to save them.

Except for him.

He left this part out of his plan, to use a modified Flying Thunder God Technique to teleport everyone out of the city, to his previous mark made before; he would be so out of chakra, he’d have to teleport everyone but himself. But he kept this secret, as they initiated the plan for mass teleportation, via a barrier that encompassed the whole army, with the help of Mamoru (who used ink birds from Gyuki’s chakra, which overrided the barrier, as the Tailed Beast’s chakra is somewhat different from the chakra the barrier was preventing from forming) and Yoru’s kunai. It was a success, leading to everyone being out of the city, of course except for Yoru himself, who had chosen this fate to die in the city alone. The barrier had even transported the remaining rebels outside to the plains beyond the city.

Kei had begun to cheer alongside Mamoru, till Darui and Gyuki brought it to the attention of them, and the leaders of the army, that Yoru wasn’t among them. Panic and fear chilled Kei’s bones instead of the cold, as he and the others realized he left himself in the city, to protect himself from dying of chakra exhaustion.

Meanwhile, in the city, Yoru laid out on a building, smiling at the thought of his friends. He smirked as he realized he thwarted the rebel plans, and succeeded in saving everyone, besides himself. He laid there, too weak to move, proud of himself actually. Though he was on death’s door, he had succeeded on a spiritual level; he had won the game of life. He had beaten the Curse of Hatred, a curse that had caused problems for the Land of Lightning via two Uchiha, and had been sparked in him by his older brother Itami doubting Darui, and the Kumogakure leadership before defecting from the village. However in the end, Yoru didn’t let the Curse win, and let his final act be for the good of Kumogakure. As he counted down to his death, he hoped that his last act would help his Country for times to come. And then, he looked up into the sky, and wished it so. And then, he was gone.

Fury had flashed, and Kei and the others could see it from here. Mamoru could sense that Yoru was gone. Their close friend had sacrificed his life for Mamoru and for the good of Kumogakure, which saddened them greatly. However, it did give Mamoru and Kei hope and a new resolve. Much like C’s death, Yoru’s heroic sacrifice gave Kei a determination to do better for Kumogakure. His close friend would rub off on him, the honorable Uchiha. And to this day, Kei remains inspired by his true friend and rival, as he works to help Kumogakure grow and prosper.

After the unleashing of Fury, the remaining rebels surrendered, as they were very much outnumbered and without resources. A truce was called and the civil war was over. Both sides agreed to unite, and honor Yoru for his heroic sacrifice. In a surprise twist, Darui decided to stand down, and retire, giving the position of Raikage to the very object of the Civil War itself, Mamoru.

Kei was seeing change in his grand village, for the better as well.

Aftermath, Becoming a Leader and Teacher
After the war ended, Darui would soon appoint the 20 year old Mamoru the Sixth Raikage of the village, and Mamoru would assign Kei to be his tag team partner, and serve an important part in Kumogakure’s government. After honoring the hero Yoru, who came to be known as the Guardian of Kumogakure, Mamoru and Kei went right to work building up Kumogakure, especially their military force. The climates stabilized around the Land, resulting in four long standing ones, instead of multiple changing climates in various places. These climates were also somewhat more peaceful, instead of natural disasters, though those still happen from time to time. It really showed Kumogakure was changing.

Kei would do his part in building Kumogakure, by leading the ANBU, with his old friends from the Academy, Enkyo and U. He would also resurrect the Kinkaku Force, which would serve many purposes, but indeed one major one that they all fall under, supporting the Lightning Country. With this Kei took the codename K, and began to go hard at work raising the numbers of the ANBU and their strength. They would become a powerful force, and some would join the Kinkaku Force.

Kei would also train to where he is in the lightning release today. He would perfect the principles; the aspects needed for free manipulation and creation of the element, get around the basic weaknesses of lightning, as well as travel to the oceans of the Lightning Country’s borders and make a contract with the Jellyfish. He would spend time refining all his techniques for over ten years, becoming the maven of electricity he is today. He would interact with many in this time, and become famed outside Kumogakure as well for his prowess in the Civil War. In Kumogakure, he’d become known as Raisenshi, and Raijin, for his prowess. He’d even learn and expand on Hell Stab, after learning the basics from Gyuki sometime during this time period and then using his knowledge of Lightning, perfecting it and improving on it. Along with Black Lightning and White Lightning, Kei would truly master lightning during this period of stability for Kumogakure.

With all this, Kei became a perfect leader for Lightning and the Cloud, handling the village affairs somewhat, along with leading the ANBU and Kinkaku Force. Alongside Mamoru and his other friends, and the village Elder Darui, he hopes to make it into a nation which both Yoru and his father would be proud of.

It is known that during this time period, Sakasudan no Panem, the circus had performed in the Land of Lightning. Kei would be dispatched, along with others, to stop any Lightning citizens from stowing away in the circus. Kei would stumble upon the circus escaping as the Kumogakure unit stopped the show. Among the group, he would see an Uchiha and his sister-figure, Kiyoko Izumi. The latter a Kumogakure runaway, Kei would quickly overpower the Earth Release woman, and quickly kill her, in the name of the village. Leaving Yoshida left, he chose to spare the Uchiha, despite the new rules imposed on killing all Uchiha. The young one reminded Kei of Yoru basically, and he grew fond of him. Speaking in his favor to Mamoru, Kei would watch over Yoshida while becoming a friend and teacher of his. Many would even consider him a brother-figure to the Uchiha. After befriending the Uchiha, it is known that the young one shared his Will Flame with Kei, allowing for Kei’s own Will Lightning and Sage Mode. It is hinted Yoshida may be the one Kei picked as the successor of the Black Lightning, but this is unknown. This circus incident happened around 2-3 years before the current timeline begins.

Personality
Duty and wanting of recognition.

These are the two personality traits he has the most. From his father, he gained the sense of loyalty to the Cloud name. Dedicated to the Cloud, he strives to establish Kumogakure is a splendid village. One not to be taken lightly. One that is truly safe. With this sense of obligation to the village, he'd almost anything for the village. He has this innate sense of of duty to Kumo to make the Cloud the best it can be. This extends to his position in the village, as head of its ANBU, and the position he took in the Civil War, in order to protect Mamoru for the better of Kumogakure.

Kei is also a capable leader. As seen during the war, he is capable of making decisions on his feet. He always acts in what he thinks is best for the force, and doesn't risk others without cause. Many in Kumo come to follow him,as they notice his sense to take charge for the better. In the middle of a dire situation, Kei can be known as one of those who keeps his cool, in order to lead a pack. He often keeps a calm and cool, collective nature in most situations. Having been through a war, nothing startles him except the most dire of situations. This unmovable calmness makes him capable of doing the most secret missions, keeping his composure at all times, being a great leader as well able to assess situations and make appropriate solutions.

From his mother, Kei has inherited the feeling of wanting to be known. He aspires to not be overshadowed by those with talent, or reasons to be well-known. He isn't jealous of anyone, he just doesn't like to be taken lightly, or be unrecognized, when he himself does have talent. This trait of his caused him to pursue a Lightning Master career, to be known alongside his childhood friend, one that could've easily overshadowed him. His pursuit to be well-known also caused him to follow his parents wishes and become a high ranking shinobi, that surpasses his father. Seeking recognition is somewhat his drive, and helped him discover his passion for Lightning Release.

He loves the Lightning Release. He gained the affinity for the nature from his father, and in an effort to become well-known besides future heroes and martyrs, he pursued a career in mastering the nature to its fullest. Lightning to Kei could be described as one of his friends. Kei is one of those people, who may observe thunderstorms, because he enjoys the sight of lightning, and also electricity. He understands it, like the back of his hand.

Kei has also been seen to like physical fitness and meditation. In an effort to become stronger, Kei honed his body to the best it could be, matching A and the Third in durability. Having done this in order to be in peak condition (to be the best shinobi possible for the Cloud), he loves to exercise as a pastime. He also likes to mediate on things, and thinks about life often. Because of this, he is very creative, however not as much as Mamoru. He just thinks freely, and many ideas form in his head because of it. As a result of his Black Lightning training with Darui, it is not uncommon to watch him meditating, or thinking about a variety of things, constantly building spiritual energy. And constantly thinking about what's best for his home, the Hidden Cloud.

Kei also seems to share some ideals with his late friend Yoru. He is an active believer of justice and honor, equality and freedom. He is an idealist in that regard, holding those virtues close to his heart. Also, Kei has a very high maturity, in conducting himself, as he tries to set the standard for Kumogakure.

He has also been shown to be very analytical, in combat, and in conduct.

Appearance
Crystals of blue.

Words used to describe Kei's eyes, which pale out in direct intense light. Complimenting Kei's light white gray mop-head locks of hair, they go along with his youthful face, which framed by his hair's bangs. With a complexion of light milky brown, a combo of his parents skin tones, Kei fits the look of a normal Kumogakure resident, on the contrary with his father. Kei has a strong, youthful build to fit his extreme durability, and the peak he has trained his body into.

As for attire, Kei sports a variety of clothes, unique as a shinobi. He usually wears some collared long sleeve shirt, either yellow, or dark blue in nature. Resembling the shirts that go under suit coats, one could say Kei has a sense of dressing nicely and presentably. However, at times, it can be noted to be untucked, or partially unbuttoned. Kei usually sports the opposite tie color, in relation with his shirt. Yellow tie on blue shirt, and blue tie on yellow. Though his tie can be black or reddish pink as well. This makes his ties stand out, and shows more prominently his good dressing style.

Over the dress shirts, Kei also has two kinds of jackets. One hooded, one not. The hooded one is dark blue in color and made of a light but durable fabric, denim, extending down when worn almost to Kei's knees. Outlined at the shoulders, around the hood and down the zipper lines with dark gold, make it pleasing to Kei. The zipper seems to made out of metal, plates that lay together and are zipped to connect. He commonly can be seen with it, especially when with the ANBU. His other jacket is white in color, and is collared much like his dress shirts. Outlined with yellow, black and blue lines, it shines in the light. Also pleasing the Kumogakure shinobi, he uses it casually usually to not compromise stealth during missions.

Kei wears darker pants, with many pockets. In the rungs at the top, a belt loops around, however, this is only for show, as it isn't very practical in combat. The belt is an unnecessary accessory for the shinobi. Chains also loop from the pockets, and the belt, which are suspected to be used in Kei's battling style. He seems to sport blue sneakers for footwear, especially efficient and capable for running hard, and hard terrain.

Other accessories of the Kumo ANBU head include his fingerless gloves, blue or black in color. Excellent conductors for lightning as well, the fabric they're made out of. A red ring, solid in nature, is sported on his wrist. Actually a vambrace, unique to Kei, he uses it for forceful strikes, and to focus lightning and electricity. On his ties, he can be seen with clips of metal on them. Though, not often.

Speed
Kei is naturally fast, a sprinter of sorts. He has high speed endurance, and easily considered a quick human, even without lightning assisting him. He can keep pace with most shinobi, and is known as the fastest shinobi in Kumogakure (without chakra enhancement). His speed spreads to his handsigns and jutsu execution, he can do those faster than a normal shinobi. He is also quick to recover from attacks, or blows. His speed as of now can be compared to the natural speed of, due to all of his physical training. Note, this is even before Kei equips the Lightning Release Armor, then his speed boosts tremendously.

Abilities
Kei is a powerful shinobi, who is strong enough to serve as a bodyguard to the Raikage. A master of lightning, he has come to tame the powers of Hell Stab, and make them his own. Many fear facing him just because he has mastered the Third Raikage's greatest technique, and on top of that, improved it. Also, Kei has great skill in taijutsu as well, along with the other art of genjutsu. He also has powerful reserves of chakra, which assist him in dealing out powerful lightning techniques. Kei's mind also helps him put to together battle solutions, and how to use his chakra efficiently in battle, so he can bring out the many capabilities of his.

Kei’s prowess has been rumored to mirror that of the First Raikage, which is a testament to the powers of Kei as well. The First was a God of Shinobi, as the First five were, and his Lightning prowess was much like Kei’s. Basically saying Kei is his second coming is proof of Kei’s power, cunning and talent. Many have said Kei has surpassed the Kages before him, and could stand equal with the one who conquered all of the Land of Lightning, the First Raikage.

Kei has been said to be the man next in line to be Raikage if Mamoru ever had to step down; if the Kage position was not Mamoru, it would most likely be given to Kei, said by Mamoru himself. Kei is a Kage-level shinobi, and serves as an amazing tag-team partner to a Kage and jinchuuriki, Mamoru, because he can match his power. Kei is skilled in many fields, and revered as a god of the lightning nature for his complex mastery of it. This makes Kei someone not easily taken down, and someone who should never be doubted or underestimated. As said by Kei himself, the opponent could shockingly regret doubting the powers of Kei Yotsuki, though he at first was not the most notable of his allies. He has made himself very notable through skill and hard work, and has surpassed and matched legends, making himself one as well.

Ninjutsu
Kei employs this style of ninja combat as one of his main ninja styles. Using his chakra directly is his major way of attacking on the battlefield. By focusing on the aspects of shape and nature transformation, along with chakra control, and output and flow, it allows for Kei to use ninjutsu effectively, while on the battlefield, or for everyday things.

Kei has great skill in basic techniques, due to his continued practice of them, and his chakra control. In terms of chakra cost, the lowest amount necessary is needed for Kei to implement these basics. This allows for Kei to simply execute these techniques without much focus, basically like second nature to him. This allows him to focus on higher tier techniques, without worrying about the basics that enable him to do this. And the same go for his lightning principles, as with mastery over the basics, he is able to do spectacular feats without much effort. This is all based on his good ninjutsu basic foundation.

This skill in basics includes mastery over the Transformation Technique, Chakra Flow, Body Flicker, Body Replacement, Tree and Water Walking practices, Hiding with Camouflage Technique, Chakra Suspension, and Chakra Enhanced Speed, among others. With good basics, this allows good combination techniques using basics and another technique. For example, Kei is particularly skilled in the usage of Lightning Release Armor and Body Flicker (or Enhanced Speed) at the same time. Kei is also skilled in nintaijutsu and Nin-Kenjutsu as well, utilizing his mastery over chakra flow and ninjutsu to do so.

Kei also displays the efficient use of Shadow Clones, along with the sensing ability. The Summoning Technique and the Mystical Palm Technique are also techniques under his repertoire, all used effectively and uniquely by his perfect chakra control and efficient mind.

Kei is also a master of nature transformation, in the forms of lightning and light, the next step of the nature. He has displayed adept skill over the nature in battle, and can even use Light to hide his presence, among other things. With his natures, the capabilities Kei can do are almost endless.

These things allow for Kei’s talented ninjutsu usage.

Summoning Technique
Having made a contract with the Jellyfish sometime after the Civil War, he can summon them to the battlefield to fulfill his will. He is not limited to the type of jellyfish he can summon, as he picks which type of species and size suits the situation best. The jellyfish, being users of chakra, can also survive for much longer than regular Jellyfish outside of water, and fight in combat for over three hours with tire.

Normally, Kei employs these beasts for water travel, or for their lightning affinity. In a water battle, they could be very effective in sending stunning or numbing blows through the water, by generating lightning. Lightning-natured jellyfish are what he can summon, able to generate lightning at their tentacles, and utilize varying lightning techniques. They can easily assist Kei in a battle.

He can summon types of Jellyfish that suit him, from hard domed jellyfish, to ones with long tentacles. These jellyfish are somewhat super powered, allowing them to move and fight upon land. However, they are more effective in the water, their natural habitat.

Electric Mastery
Kei is reputed as one of the greatest users of Lightning Release, if the not the best, to ever live. He has taken his natural affinity for the element and turned it into a true mastery few will be ever able to match. His mastery makes him seem godly when he activates the element by vibrating his chakra. With his knowledge of the aspects of lightning, and his experience with it, he is able to actively control and shape electric chakra, into a variety of shapes and forms that can cause paralysis, numbing, and death quickly and efficiently.

This leads to expertise in manipulating and generating lightning on the battlefield, and allows for him to exert dominion over the type of chakra on the battlefield. Manipulating the flow of lightning, so if it is being used offensively against him, it can be redirected around him, nullifying the lightning chakra completely and much more are all possible with Kei’s complex mastery of lightning, which has been harnessed since his childhood. His mastery has achieved triumph over the basic weakness over Lightning, air’s natural insulator, by increasing lightning intensity. Lightning is his canvas, essentially, from which he create what he wants.

For Kei, hand seals don’t even have to be done for him to initiate using it. All he has to do is vibrate his lightning chakra in order to generate the electricity in the form he needs. By using hand seals, he can create his most powerful lightning techniques, and cause mass destruction. Kei’s prowess with the Lightning Release mimics not only lightning, but other abilities such as Kekkei Genkai as well, that have lightning as a component.

Lightning Release is his main form of combat; however, it is not his only. Regardless, when using Lightning Release, many spectacular feats are easily done, as the Lightning Release takes the least amount of chakra for him to employ, second only to basic techniques. His Lightning is also much quicker than those of others, for he is truly a master of the chakra nature, and its varying forms. Essentially an extension of his wills when he uses it, he is truly one with the lightning nature, and his chakra is noted to be closer to lightning-chakra at its normal state, due to its affinity, capable of shocking those who absorb it or touch it.

These powers at their height, do relate to natural lightning as well. He can even control lightning from the heavens at full power. Besides just basic lightning, Kei has taken a mastery of different variations of the skill as well, such as black and white lightning, and light, the pinnacle of the nature. All of this contributes to making his prowess with electricity one of a kind, and unsurpassed.


 * Altering Form: This particular aspect refers to two things, instead of one like most. The first refers to more of its state, the state of the lightning formed. Lightning Release doesn’t always have to be generated bolts of lightning and electricity; it has some other forms as well. Though it has the same effect almost, Lightning Release can be generated as bolts, beams (lasers), flowing energy (much like the Lightning Armor), or quick pulse shockwaves of energy. Kei has mastered each form, and can generate each one at will. Along with the next part of this principle, this plays an important part in how Kei uses his nature transformation. The state it is in can have much to say about its abilities, such as the Lightning Armor, to a wave of electric energy like the Lightning Armor, or something like Lightning Release: Pulse Circuit Technique.


 * The second part of this aspect refers more to what form actually is, a three-dimensional shape. This relates to his understanding of current basically, to follow the lightning element into various shapes and forms for his usage. With mastery over chakra flow and control, he can flow the chakra needed perfectly to form anything out of electricity, of various sizes and powers with the least amount of chakra necessary. This allows for Kei to constantly shape things from the energy of Lightning Release Armor, such as Hell Stab, or constructs being formed from the hands, such as swords made from pure electrical energy. For him to extend his Lightning Armor into pinpoint spikes that expel from him, all it takes is some thought, and his chakra conforms to his imagination. Whatever fits the situation, Kei can shape his lightning states into. He most commonly does this through his LRA, his most commonly used technique.


 * With the power of form, he can create various things, from dragons of electricity, capable of breaking powerful walls like Rashōmon, to balls of electrical energy, packed with power. He can also form waves of energy, much like the flowing energy of the LRA, to shock opponents over wide ranges, or manipulate the bolts of lightning into pronged like shapes, for extended reach, or attacking more than one opponent at the same time.


 * He even has powerful control over this flow at long range. Remotely, he can shape his lightning balls into blades for his sword handles. Regardless of how big or drastic the form is, Kei can utilize lightning to create various forms for varying purposes. From subtle battle use, to large, destructive use without any effort at all really.


 * This principle works hand in hand with current, as the forms are all made with current.


 * Amperage, Flow, Current: Electricity flows in a current. With mastery of this, Kei can effortlessly move his constructs, and give them reach, or effectively cover an area in electrical energy. With control on how he wants the lightning-chakra to flow, he can guide the current into creating the form he wants. This aspect had to be mastered first, before anything else, as the current is a major part in even utilizing lightning transformation. If there is no current, there is no effective usage of the lightning element.


 * Kei understands how lightning and electricity flow, and this allows him to use utilize chakra flow to actually achieve that with his own lightning. With his mind, Kei’s electric power flows easily and freely, much like a performing bird. It has no bounds in regards about how it flows. To top this off, Kei can achieve this effortless flow simply with his mind, and not much thought is needed to effectively flow current into forms, or into an attack. When he actually does focus, he can manipulate the flow so it can keep up with even the fastest shinobi, those who share the ability of LRA. This shows Kei overall prowess in this principle, as he has no limit to what he can do, and how he can flow and conduct current to what he wants, in a variety of forms and states. Many have said that his Lightning flows akin to Storm Release; this shows Kei can mirror the flow of electricity through conductors, for smooth movement.


 * Cutting and Piercing: By focusing current, Kei can achieve these two abilities. By concentrating current, and forming it into constructs of various states, he can concentrate to a certain point, where the lightning serves to cut and slice through objects, much like a sword. This ability is increased with swords as a medium, allowing swords to cut through even the ribcage of Susanoo. However, using Lightning chakra to cut allows a wider range, and can still cut through various barriers based on the earth, steel, etc. To pierce, all Kei has to do is concentrate his lightning chakra more, in order to form piercing power, such as the Hell Stab. Kei can vary the concentration in order to cut ice, steel and earth, or to cut even fire clean through, or pierce straight through it, through the solidification and the lightning’s nature being close to a sword when he concentrates it. By giving it form, he has a variety of ways to achieve cutting or piercing lightning, whether lances with pinpoint tips, or lightning swords, or crescents of energy that have this property.


 * Electromagnetism/Electromagnetic Lightning: Focused current, coiled current. By doing those two things to the extreme, Kei can generate the power of electromagnetism, and Electromagnetic Lightning, the latter being easier done, requiring only very focused current. By focusing his chakra, he can form lightning transformation with high magnetic properties. Allowing the lightning to attract metal based materials, and things not metal based, such as people with the magnetic fields generated, however the metal based objects are attracted more easily, with less chakra. This trait can also be applied to concentrated constructs of lightning, allowing Kei to form for example, concentrated swords of lightning energy that can attract and repel things at his command.


 * By concentrated, and coiling lightning chakra within himself, Kei summons forth his manipulation of electromagnetism. With the concentrated energy within, Kei can control and generate electromagnetism itself, giving him the full powers lightning provides, as well as magnetism. This allows him control of many metal based objects, as he can easily generate magnetic fields that attract them, and cause them to orbit him, as he utilizes them as weapons. He can do this with his swords, to rotate them around himself, and fling them at the opponent like deadly needles.


 * He can also generate electromagnetism as powerful energy that can be fired in the form of beams of energy at the enemy. These beams have varying intensities, based on what Kei desires. They do pack a lot of force, and can electrocute or numb his targets.


 * With complete control over magnetism, Kei can utilize repulsion on the ground to achieve flight, and combine this with his Lightning Release Armor, to become even faster. With this power over electromagnetism, Kei can also generate fields of magnetism, and electricity at will (that he can constantly shape and flow around to shape his needs), and even release pulses of energy (EMPs) that cancels out electrical current, and therefore, nullifies Lightning Release attacks used on Kei. This is one of his many ways of dealing with enemy lightning.


 * Electromagnetic Aura: Electromagnetic Telekinesis. Just really an application of his control over electromagnetism, it allows him to control the electromagnetic forces affecting everything in the world, and generate, and strengthen so he can literally use electromagnetic force. By pulling on this force, he can attract things to him and repel them with ease, allowing for him to achieve telekinesis. This also allows him to use the fields generated to crush objects with magnetic force if needed, to weaponize, or destroy them. Kei can also control the pull, and how powerful the push is, without much effort. He could easily crush solid metals, or reverse the motion of moving, thrown boulders.


 * Pull to the Blazing Field: A magnetic skill Kei commonly employs. By generating a barrier of lightning around himself, a dome if you will, he can then pull an opponent towards the construct. This pull is almost unresistable, and almost ensures the opponent meets a terrible end. Only those skilled enough can escape this simple, but deadly technique.


 * Frequency: 


 * Intensity: Another aspect, this refers to the strength of the current Kei creates. He can easily mandate and regulate how strong the current flows, for a variety of effects. This is one of the more important aspects, because depending on how much Kei resonates his chakra frequency in preparation to generate lightning, determines how strong the current generated will. With the more vibration of his chakra, the strong the current is. By increasing current strength per se, Kei can have his electric energy serve a variety of purposes. This means Kei can strike to kill with overload of electric current (shocking, burning), or strike to disable through numbing and paralyzing intensities. For his base lightning, it fluctuates from being harmless, and the current being used as a sensory medium, to the burning and shocking. The intensity is determined how much Kei increases high frequency vibrations of his chakra, (how lightning release is created), with the stronger effects requiring higher frequencies. Kei’s mastery over this aspect allows him to create various currents of varying intensities at the same time, all the while adding the other aspects and concepts as well. Kei can commonly employ this to dispatch his opponent quickly, either killing them, or paralyzing them and leaving them unable to finish the fight.

Will Lightning
A form of Kei’s will, it is a form made of spiritual energy made solid and dense. After sharing in the Will Flame of Yoshida Uchiha, Kei would develop an aura similar to that of the young Uchiha. His spiritual energy solidified with just a tint of yang and the natural energy Kei himself produces (little as it is), it isn’t really a chakra form, but rather the force of Kei’s life, and will manifested and is therefore powered by it.

Akin to the LRA, a sheet of lightning forms around Kei, sparking with bolts; this is the Will Lightning. However, it doesn’t electrify his nervous system, and serves basically as an armor of Lightning, without the speed effects of LRA. This form allows Kei to gather natural energy, and enter Sage mode, using his own natural energy as a medium in the sheet. The sheet manifests both consciously and passively.

Passive Effects:  A manifestation of Kei’s will, it acts almost as an everlasting defense. Always there, materializing when Kei is endangered. This means, even if Kei is caught off guard, the Will Lightning will manifest (at the speed of natural lightning itself- due to the natural energy within) in a blue-yellow-white color, white lightning, and vaporize whatever threatens to harm Kei. Kei lives to protect, and serve Kumogakure. The Will Lightning protects him so he can continue to do so. This happens without Kei even having to think about it. When the Will Lightning comes in contact with energy, it absorbs the spiritual energy of it, usually of a jutsu, causing the yin-to-yang ratios to collapse and the technique to disperse, and the energy be converted into the Will Lightning itself.

Conscious Effects:  The Will Lightning is stronger when Kei manifests it consciously. When made by Kei’s thought, it is still white and serves as armor protection. But it also takes on the easy to shape properties of Black Lightning. The conscious abilities do take chakra, but not much with Kei’s understandings of the many aspects of lightning release mastery. He can then proceed to mix his chakra into the Will Lightning and apply shape transformation, much like his usage of Lightning Release Armor. These constructs hold natural energy within them as well, allowing for minor senjutsu attacks that can do more damage than regular LRA manipulation. Kei can also hide the Will Lightning altogether, using his Light Release techniques to hide it from view. Kei can also change the intensity of Will Lightning if he chooses, allowing him to share it with others if he wishes. Also through the Will Lightning, he can detect the electromagnetic fields he creates more easily, as it serves as a sensory medium for Electrolocation.


 * Natural Energy & Sage Mode: While normally just tinted with natural energy, in order to perform amazing feats, the Will Lightning must gather natural energy. As long as Kei doesn’t manipulate it, it is possible for it do so, as it stays still. This allows Kei to actually manipulate natural energy, without actually entering Sage Mode, through his Will Lightning. This allows for Sage Arts done with Lightning, through the Will Lightning, with Kei ever having to enter Sage Mode. Things such as Sage Art: Yin Release Lightning Dispatch can be done without Sage Mode, though only when Kei enters Sage Mode will it be at full power.

To enter Sage Mode, Kei must absorb the Senjutsu chakra gathered by the Will Lightning, and merge it with his own. This process is rather quick, as the chakra is already melded. When Kei enters Sage Mode, sparks are more prominent, and the Will Lightning radiates with life. The Sage techniques it performs are enhanced with much more natural energy from Kei and therefore are at full power.


 * Electric Avatar: A power unique to Kei, it is his Will Lightning given massive form. Similar to a Susanoo, Kei can manifest his Will Lightning into a huge titan of equal size. This possesses powerful destructive force, just by size alone. Also, by being a giant elemental construct made from spiritual energy, it has powerful force using its huge currents it possesses. And like its original form, the Electric Avatar can be manipulated much like regular lightning. However, Kei rarely uses the full form, as it would tire him out mentally and would expend notable chakra. Instead, he manifests parts with his Will Lightning, manifesting arms, legs, etc of the giant being. It also allows for widespread Lightning Release techniques, by simply manifesting an arm. It makes Kei’s widespread techniques quicker, and could potentially make them more powerful with the huge medium. When in Sage Mode, the Electric Titan’s power is enhanced by natural energy and senjutsu chakra (like the regular Will Lightning), making it truly formidable.

Taijutsu & Durability
Rough, powerful and durable.

Kei doesn't look pretty huge, but he sure packs a mighty punch. His taijutsu style revolves around dominating the opponent, with his honed physical strength. After training in the Cliffs of the Land of Earth for so long, his physical ability has peaked, using the Strong Fist style of fighting, along with some of the techniques of the previous Raikages wrestling like style.

A single punch from Kei seems to be able to shatter rock on average, a testament to his strength. His speed and agility are tremendous, able to keep up with most fast paced animals, even cheetahs. This is even more augmented by his Lightning Release Armor, which brings him to a new peak of those things, capable of keeping up with the legendary Fourth Raikage, A, and land his powerful strikes in a flash, a streak of lightning. His kicks seem to be enough to break bones.

Kei is also very durable, capable of taking direct beatings from a person enhanced by the first two Eight Gates, and still continue to fight like usual. He is capable enough to keep up with them at his natural honed speed, and with Lightning Release Armor, even surpass them in speed, and power. Kei is also resistant to pain, refusing to be deterred from say a broken arm. He would continue to fight even then, while most wouldn't. This is also a testament to his stamina in a fight.

Kei combines his taijutsu with Lightning Release Armor, and other lightning jutsu. This allows him to fight in the unique Lightning Release Nin-Taijutsu, where he seamlessly puts together Lightning Techniques like Hell Stab into the battle, along with his own physical ability. He can quickly follow up a punch with a Lightning Release Stream, or a lightning construct. He could integrate his constructs of lightning into melee combat, such as fashioning a blade of lightning, to fight with during combat.

Kei's timing for taijutsu is precise, and when he works with lightning, he is one and the same with it. Lightning Strikes done by Kei are quickly followed up by blows, like lightning is his partner during a battle. Kei also uses lightning as an extension of himself really, with Lightning Release Armor, Hell Stab, and their manipulations, converting their shape into various constructs he can weave into combat with himself. They can serve an extra reach for a strike, or to stop an opponent if they ever got behind his speed. Kei's taijutsu is electrified with lightning chakra, and is powerful, with or without it.

Kei's powerful body seems to be directly related to his lightning affinity, and his pituitary gland. Many have compared Kei's physical prowess to that of the Raikages, which leads to belief Kei can destroy cliffs, and shatter swords with his phsyical strength and power, of one hand. This also means, even Chidori can barely pierce his body, if it manages to touch it at all.

Kenjutsu

 * Cloud-Style Electric Beheading: By using his understanding of chakra flow, he can flow lightning-natured chakra through one of his blades. By then slashing out into the air, the chakra vibrates and produces lightning beams, and shocking energy that follows the direction of the arc made with the word by Kei. He can use this in quick succession to issue out waves of electricity at the opponent. If he flows a lot of lightning chakra into a sword at one time, he can literally form a defensive ring of electric energy, a wall of lightning, vibrating chakra, that electrocutes all who tread to close to Kei.
