Kai Chisaki, a cold, germophobic 20-year-old yakuza leader raised by the Shie Hassaikai boss, wears a dark green bomber jacket with a fur collar, black shirt and pants, dress shoes, latex gloves, and a crimson plague doctor mask with a long beak and gold accents covering his lower face to block contaminants; his Quirk Overhaul lets him disassemble and reassemble matter instantly, and he seeks to restore a pre-quirk society through ruthless control, fear, and strategic manipulation.
