Kazushi Kaguya is the Descendant of Kaguya Ōtsutsuki,and cousin to Kimimaro.He is a member of the Kaguya clan and a ninja of Oto After abandoning Kiri to escape his clans massacre and Orochimaru finding him along with Kimimaro he is now an oto ninja.
Kazushi has a rather solitary, and matter-of-fact attitude. His calm and detached demeanor has been called "cool" many times by Karin Uzumaki. Despite his increasingly growing reputation and prowess as a ninja, Kazushi has also shown to act like Madara when it comes to fighting wanting to get his blood pumping when fighting but is not arrogant when it comes to fighting.
Kazushi is recognized as a prodigy, along with both of his two teammates. They all act well as a team, each knowing their places.
When he was 9 years old Orochimaru injected him with the blood of a Yuki giving him Ice Release. Training non-stop Kazushi was able to make it so his water affinity was on par with Tobirama Senju. With his water affinity he can use water from the atmosphere and use jutsus like Mizukiri and Water Release: Rain Storm. He is able to make ice cold enough that it can withstand multiple fire release jutsus when using jutsus like Demonic Mirroring Ice Crystals and Ice Release: Glacier Vapor Storm. Because of having Ice Release Kazushi is also able to use Wind Release using jutsus like Wind Release: Air Blades and Wind Release: Vacuum Sphere.
While training time with Orochimaru, Kazushi had killed Gato and raided his mansion. There he found the Wolf Contract and when signing it he summoned the wolf Mizuru. Mizuru later took Kazushi to Gōzen Ridge where he was tested by the leader Kōkiga who granted Kazushi the ability to summon Wolves. Kazushi can mount Mizuru for fast travel and can also preform collaboration techniques with her.
Due to the larger chakra reserves he has, Kazushi is able to learn senjutsu from the Great Wolf Sage at the Gōzen Ridge. This allows him to enter Sage Mode, which he can use indefinitely. In Sage Mode, Kazushi's only noticeable physical alterations are the markings around his eyes, his eyes becoming yellow ,gaining claws and gaining marks on his face. Using Sage Mode makes Kazushi's jutsu and physical attacks stronger, improves his physical defenses,heightens her speed and reflexes,and allows him to sense his surroundings. He can also infuse natural energy into inanimate objects, giving them life.
Kazushi is known to be a master of his kekkei genkai, basing his taijutsu prowess on it.The main capabilities of Shikotsumyaku is allowing the user to manipulate the speed of their bones' growth as well as the location of calcium deposits allowing for great versatility. This allows them to create weapons of bones that can either protrude from any part of the body, or pulled out and used like handheld weapons. The user was also able to create armour of dense bone underneath their skin.They can even fire pieces of their bones as long-ranged projectiles. Any bone that they remove from the body immediately regenerates, as does the skin that is damaged when the bones are removed.
Although it seems it takes a bit longer for the limb to become usable again, unless the user regrows the bones consciously. Users can increase the density of the created bones, making them stronger than steel. This not only makes the created weapons very powerful, but also makes their bodies virtually indestructible; the bones can withstand even a chakra-infused blade, which is usually enough to cut through anything. However, as Kimimaro demonstrated, the bones can also grow quite a large volume, and likely grow from each other, as a form of a ninjutsu, and that he can emerge from any of these bones.
Orochimaru even once stated the kekkei genkai granted the user an impenetrable skeletal frame, which can resist any type of physical attack, the reason he wanted Kimimaro's body so badly. In addition, should a Shikotsumyaku user ever go on the offensive, they could instantly turn their bones into the sharpest spear. Because of this, the Shikotsumyaku is held in high regard as the ultimate taijutsu ability.
Kazushi, like all members of the Kaguya Clan with the kekkei genkai, are naturally born with an extremely high willpower/determination, capable of forcing a fatally ailed body that would usually be unable to move into battle and still be a deadly opponent. Kazushi utilizes his kekkei genkai in battle with impressive speed, agility and reflexes, and wields some of his bone weapons with insane levels of strength.
He has been seen using his kekkei genkai innovatively, forming shuriken out of bone and manipulating them with chakra threads, with these shuriken being much more powerful than regular shuriken in addition to having a nigh-limitless amount that can be easily infused with elemental converted chakra. One of his techniques even entail him forming a blade out of his bone and utilizing it in combat.
Users of Shikotsumyaku possess a unique, and often overlooked, healing factor. It is often seen when their skin heals after their various bone removals. Kazushi's body regenerates at a faster rate than the average human. Naturally, his healing factor can heal smaller wounds in minutes, and more fatal wounds within hours. And by coursing chakra into a specific area, Kazushi's healing factor is further increased. Breaking a bone is hopeless as it is nearly impossible. And if it does occur, he can regenerate it within seconds.
Perhaps one of the most terrifying aspects of this bloodline limit, is the fact that bone can grow out of already existing bone that has been fired, meaning that even one bone can become extremely deadly, and becomes even worse in the hands of one who has acquired skill in the D-Ranked techniques that Shuriken jutsu is associated with. Kazushi understands that while the ranking is one of raw power, it is not one of versatility, with C, D and E ranked techniques being theoretically some of the most useful techniques a shinobi can have in their arsenal. By changing his skeletal density, he can render himself extremely hard to move by most external forces.
It should be possible for Kazushi to even shield his internal organs in ways that he does not even know he can, but this will be accomplished over time and through his acquiring of experience, in addition to his status as a member of the Kaguya Clan's Main Family. He has however, to some extent created internal platings of bone to cover his pressure points. He even can use his techniques in ways that some would consider unpredictable. Kazushi learned how to subconciously call upon his kekkei genkai to protect him. Kazushi is even known for nigh-instantaneous creation of bone structures with astonishing flexibility, and can even deteriorate an enemy's bones should they annoy him too greatly.
