"An unbeatable person isn't one who has a lot of power, rather it's one who has mastered the power they already have."
Not much is known about his physical appearance due to the fact that clothing covers his whole body. The only thing that is known is that he has red eyes. Haru wears a skeletal mask, he also wears a black cloak that reaches his ankles. The hood of the cloak is usually up so that people can't see his hair. For pants, he wears plain long black pants, and for a shirt he wears a long sleeve black shirt. Haru has bandages that go from his elbows to the tip of his finger tips.
Haru is a really mysterious character. No one can figure him out. One moment he is being a hero and the next he is a sadistic monster. His goals are also unknown. The only thing that is known about him is that he cherishes his sister and other mutants.
Haru's intelligence is average for someone his age. His wisdom however is a different story. According to the rumors Haru's wisdom matches Hagoromo Ōtsutsuki. This rumor hasn't been proven but judging from Haru's actions it isn't completely unbelievable.
Demon VS Hero
Like every living being, Haru has a malicious alter-ego and an inner hero. Except his malicious alter-ego and inner hero are a lot stronger than others and they aren't just part of his subconscious like others are. They are as real as himself. They don't provide him with extra strength but they do control his personality. His malicious alter-ego and inner hero have fought each other their whole life. The times when the malicious alter-ego has had the upper hand are the times when Haru has been a sadistic monster. The times when the hero has one, is when Haru has been relatively nice. If the demon were to win, Haru will be as evil as The Devil himself. If the hero were to win, Haru might become as normal as a mutant can get.
When, Yuno did some research about the two beings inside of Haru she came across a shocking realization. Yuno came across a story about a young boy who told everyone that a tiger and a dragon were always fighting in his dreams. The boy said that, that's all he dreams about and if he closes his eyes and concentrates enough he can still see them fighting. Sometimes they would change form, but the two creatures would always be opposite from each other. In Chinese philosophy Yin is shown as a tiger and Yang is shown as a dragon. The young boy had the manifestation of Yin and Yang inside of him and this time, it's Haru that has these two beings.

Part in the story
Haru wasn't always fond of swords and other bladed weapons. In fact, as a child he hated and feared them. When Haru was only six years old he came home one day and saw a sword sticking out of his mother's chest. It took Haru a while until he finally admitted to himself that his mom was dead. After that day, Haru stayed away from swords as if they were the plague.
One day, a traveling swordsman arrived at his village. This swordsman had just come from a different village to give a handicapped boy a second chance. This man, would not only help Haru get over his fear and hatred but he would also become Haru's sensei. This mysterious man taught Haru many sword styles. Including the Cloud Style, Flying Sword Style, Iaido, and Konoha's sword techniques.
On the day of December 9th at 5:00 am, this traveler taught Haru his own sword style. The name of that sword style was "Seiken." It took Haru a month to prefect this sword style and when he did his sensei taught him Rasenringu and Dai Rasenringu as a reward. Soon after that Haru's sensei mysteriously vanished.
Two years after Haru had left Konoha with his sister he travelled to the land of fire to find his Sensei's grave and dig up his Sensei's sword. Haru didn't find the grave, he did however find a rather annoying girl around Haru's age named: Nagisa Rinku. The years following meeting Nagisa would be the most peaceful and happy years of Haru's life. In fact, it's one of the only times when he has felt truly happy.
Usually, Haru would ignore people who annoyed him. But she was different, she wasn't human at all. In fact she was a vampire and she desperately wanted to train under Haru and be with him. Nagisa eventually persuaded Haru by offering to help him take care of his sister.
Haru, Nagisa, and Yuno travelled together and as the days turned into months Haru found himself liking Nagisa more and more. Partially because he admired her power and adaptability. The was another reason of course, but he would try not to admit it to himself, much less say it out loud. Haru and Nagisa's bond grew stronger with each passing day, and as her training continued they would begin to fight together more often.
In the beginning, Nagisa kept her promise and took care of Yuno by herself as Haru went out to do his mysterious outings. As time passed it became more like a family and Haru and Nagisa would look after Yuno together. Even though Haru was slowly opening up to Nagisa he didn't let Nagisa truly know what he was thinking. She tried every possible way to get him to open up, but none of the attempts worked in the beginning. That would change after 11 months of being together on April the sixth. Haru and Nagisa were both on the verge of death on the day and the only reason they survived was due to the fact that they were together. Their enemy was an Uchiha who had the Eternal Mangekyō Sharingan. On that day, Nagisa became the first person in 10 years to ever see a Haru's face besides his sister. Haru and Nagisa were eventually able to beat him when they both used Haru's trump card at the same time.
