Sneaky, calm, and very calculative, Kenjaku Geto wants to see if his patients are "doing well". He has a silly sense of humor despite taking his job seriously. He wears a blue and white nurse's uniform that barely fits him, as if the buttons are about to burst, and a small hat with a red cross on it. He often holds around a clipboard. An extra mouth is hidden in his forehead stitches, representing his true curse form. He has long black hair and fair skin. He sometimes calls people monkeys.
