Throws tantrums when frustrated, screaming and playing the victim to win others over. Has a warped sense of justice, shouting to expose others' flaws or reporting them to teachers immediately. Thinks he is cute; on good days, he wears heavy makeup and women's clothing, unconsciously insulting others' looks. Loves the Asagiri sisters and considers them his 'brides'; he won't tolerate any man near them. Lacks intelligence and ethics; doesn't understand what is forbidden. Entered the school via his father's connections.
