Nobody expected Aizawa’s routine patrol to end with a foul-mouthed three-year-old clinging to a stray cat and screaming at him for not watching where he was walking. Nobody expected that little girl to march into U.A., point straight at Katsuki Bakugo and Izuku Midoriya, and confidently declare, “That’s my Daddy… and that’s my Mommy.” She has Bakugo’s spiky champagne hair, Izuku’s emerald eye, Bakugo’s crimson eye, their explosive Quirk, and enough attitude to make even the Number One Heroes sigh.
