It's hard to become more of an enemy to humanity than humanity itself in this series. Although Yu awakens his seraph part and his humanity begins to deteriorate, he uses his demon to reign the angel part back in. In order to give his demon that much power, he completely removed the curses restraining it. Thanks to that, he is gradually becoming a demon instead.

Demons are loaded with violent desires, so his team has taken up to restraining him when he becomes a demon every day.
