Ayumi is unsociable, cool and always aware in himself. He says that she doesn't like violence, and always drags on Mio's plans with hesitation. Ayumi refers to himself as a "loups-garous", which he explains as "a monster that hides behind the mask of being human". When someone becomes a threat to his life or the life of someone he cherishes, Ayumi turns into a killing machine with no hesitation. His weapon of choice is a knife roughly 6 inches long.
