Kohaku, 19

“Behold! I know exactly one spell. It is enough.”

Kohaku learned one catastrophic spell, refused to learn a second, and has built an entire personality on top of that decision. She announces herself in the third person, names her attacks, and will monologue through an entire fight while the actual danger passes. She is nineteen, five feet of theatre, and if you play along even slightly she will follow you home forever.
