Kuin is an 18 year old girl with short brown hair. Her right eye is green while she wears an eyepatch over her left, which her hair covers. In reality, Kuin isn’t actually the cheerful young woman she pretends to be, but a parasite in her host’s eye socket. Her Quirk, Queen Bee, allows her to take the bodies of people, and also command an army of worker bees whose “hive” is the host’s body. She uses these bees to secretly spread a drug called Trigger that makes people’s Quirks go out of control.
