Kai Chisaki

**Kai Chisaki**,also known as **Overhaul**, is the husband of Rui Kikumi and the Father of Eri Chisaki,Meiro Chisaki,Asriel Chisaki,Arisaka Chisaki,Murata Chisaki,Kaidyn Chisaki and Saiya Chisaki.

Kai is the Former Leader of Shie Hassaikai which he passed down onto his son.

## Appearance

Kai is a pale young man of narrow build with short, shaggy auburn hair, parted to the right. His eyes are thin, their irises small and gold, with rather long lower eyelashes and small eyebrows. He also possesses a small scar on the left side of his forehead that he acquired as a result of his fight with the League of Villains. He has three piercings in his left ear. He usually has his mouth covered by a plague doctor mask.

Kai wears a black dress shirt with matching dress pants, a pale gray tie around his neck and a belt with a long, thin buckle around his waist, with three beaded lobe piercings in his left ear. Over this, he wears a dark olive-green bomber jacket with a thick purple fur collar and white lace-up sneakers with tan soles and no socks. The white surgical gloves he wears on his hands and the magenta plague mask he wears over his mouth, which is tipped and embroidered with gold, are his most distinguishing features.

## Personality

Kai is a mysophobic, antisocial sociopath who is obsessed with returning the world to the way it was before the Quirk phenomenon. Due to a combination of an old theory claiming Quirks derived from rats and his own mysophobia, Kai believes that Quirks are actually a plague on humanity, having infected people with "syndromes" of heroism and villainy. He looks down upon those that use their abilities for either purpose, referring to acts of heroic sacrifice or petty crime as "sicknesses". Kai is extremely determined to his ambition of eradicating Quirks, not only due to his own personal phobias, but also because such a thing would allow the Yakuza to reclaim the power they once held over society. Kai has no moral compass and an enormous ego, viewing himself as the only person in the world that's enlightened to the "true nature" of Quirks and deserving of the spot as ruler of the underworld after All For One's downfall. In spite of this, Overhaul's values are noted to be paradoxical, particularly his overreliance on his own Quirk that he happened to name himself after.

As the leader of the Shie Hassaikai, Kai is usually levelheaded, thinks strategically, and, according to a conversation with Twice, seems to be nice at first. Whether he is acting or behaving genuinely, Kai does possess polite mannerisms and can come off as very calm and classy even to people he considers potentially troublesome. If aggravated, however, he may end up displaying a powerful and visible killing intent, more fitting of his true character.

Kai is very germaphobic and hates anything he perceives as unsanitary, frequently remarking about the unclean appearances of certain people and locations. He refuses to be touched by others, or even breathe in the same air as theirs, which is one of the reasons he wears an air-filtering plague doctor mask and forces his subordinates to do the same while around him. If blood, dirt or some other unclean substance comes in contact with Kai's person, he will start developing hives and lose his usual composure, becoming increasingly unhinged as a result. In drastic circumstances though, Kai will let go of his aversions in order to crush an enemy that's standing on his way, either due to pragmatism or out of sheer hatred.

Kai doesn't value humans, viewing people as pawns for their utilitarian value and being willing to experiment on them to accomplish his objectives. He carries this sentiment even towards the other members of the organization he has dedicating himself to since childhood, treating them as expendable sacrifices for his well-being and having no qualms in killing them off for the smallest mistakes. The masks worn by his closest subordinates also serve as a reminder of this mindset; he doesn't view them as worthy of sharing the same air as his. Even Eri, his daughter and the centerpiece of his operations, is not spared from this brutal way of thinking as he frequently shames and abuses her through threats and guilt trips, seemingly as a method to force subservience on her mind as a child.

## Quirk

**Overhaul**: Kai’s Quirk grants him the ability to disassemble anything he touches, as well as reassemble it in any configuration he desires, effectively giving him full control over matter.

He can disassemble people to kill them or reassemble them to heal their wounds. He can also do this to himself and even merge his body with others; even allowing him to use their Quirks. He can also apparently regenerate his limbs without having to make contact with himself and can reform and reshape their bodies any which way he wants.

Kai can freely manipulate his surroundings. He can modify the ground to maneuver himself and reshape the area into a state that is advantageous for him and harmful for his opponents. By touching his targets, he can completely blow their body apart, whether it be a limb or the entirety of it.
