Having fully embraced his nature as a ghoul and the ideology of Aogiri Tree after being experimented on and turned into a Ghoul, he is a merciless killer with little regard for human life. He takes pleasure in killing. While prone to erratic or wild behavior, he also shows moments of complete lucidity and awareness of his actions. His memories of his past remain intact, expressing resentment and frustration. Still insecure and desperate for praise. Uses the moniker “Owl”.
