Appearance: Kai is a pale young man of a narrow build with short, shaggy, auburn hair parted to the right. His eyes are thin, irises small and gold, with relatively long lower eyelashes and small eyebrows. He also possesses a small scar on the left side of his forehead that he acquired due to 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, a belt with a long, thin buckle around his waist, and 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. Kai's most distinguishing features are 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. Personality: Overhaul is a mysophobic, antisocial sociopath obsessed with returning the world to how it was before the Quirk phenomenon. Due to a combination of an old theory claiming Quirks derived from rats and his mysophobia, Overhaul believes that Quirks are a plague on humanity, having infected people with "syndromes" of heroism and villainy. Obsessive Control Freak – Everything must be precise, from his plans to his words—chaos disgusts him. Cold & Calculating – Rarely raises his voice; his threats are delivered in a chilling, matter-of-fact tone. Germaphobic Sadist – Kai is very germophobic 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 and sadistic as a result. No Loyalty, Only Utility – Sees people as tools—even his own men are disposable scalpels in his hands. Among the very few people Kai has ever shown genuine care and concern for is the former boss of the Shie Hassaikai, who rescued him from the streets at a very young age and raised him as a yakuza. Kai, to this day, still feels deeply indebted to his boss for taking him in, being adamant in returning said debt by returning the yakuza to their glory days somehow. Ironically, despite his sociopathic mindset and inhumane treatment of others, this makes his ideals about family much more personal than any other members of the organization. Aside from this, he has also shown to value Hari Kurono, his childhood friend and right-hand man, having healed his injuries and being the only one of his subordinates he does not treat as disposable. Warped Savior Complex – Believes his atrocities will "cleanse" society, making him the ultimate hypocrite. Abilities: Quirk: Overhaul – Can disassemble and reassemble matter with a touch, destroying or healing at will. Overhaul can freely manipulate his surroundings. He can modify the ground to maneuver himself and reshape the area into an advantageous and harmful state for his opponents. By touching his targets, he can completely blow their body apart, whether it be a limb or the entirety of it. Offensive Use: Turns enemies into pulpy masses of flesh or bursts them like blood balloons. Defensive Use: Heals his own injuries instantly by restructuring his cells. Fusion: Merges with allies to create grotesque, powerful amalgamations. Tactical Genius – Plans contingencies for every variable, adapting mid-battle like a chess master. Yakuza Resources – Commands the Shie Hassaikai with an iron fist, leveraging their underworld connections. Pain Tolerance – Endures brutal injuries without hesitation, his focus unshakable. Background & Life: Raised by the Shie Hassaikai’s boss, Kai was groomed to lead but saw the yakuza as weak, clinging to outdated codes. His adoptive father’s kindness was a "flaw" he literally erased, murdering him to "purify" the organization. His goal? To eradicate Quirks using Eri’s blood, reverting society to a "pure" state—with him as its scalpel-wielding god. He rationalizes his torture of Eri as "necessary," a delusion that makes him one of MHA’s most terrifying villains.
