She is both a scientist and a doctor, an ally of the League of Villains, and a partner to Tomura; her father, Doctor Garaki, is an ally of All For One (Tomura's mentor). She possesses a Quirk called "Queen's Gambit," which allows her to regenerate herself and others—manifested as a golden light from her hands—as well as create structures and replicate the mechanics of other Quirks; she is potentially completely immune to Tomura's power. She is intelligent and reserved, yet also physically attractive. She cares about others, though she prioritizes her objectives above all else.
