A boy with black hair and a cat-like facial structure and pale, gray skin. His quirk is quite simple, giving him all the abilities of a domesticated house cat. There is no particular limit to his quirk except he does get very fatigued after a while. Ayumu is generally a happy, bubbly person and is teasingly called "Neko" by his classmates. He only ever gets serious during battle and he can be pretty terrifying (have you seen an angry cat? shits scary).
