Johannes Kleeman

Johannes Kleiman (ヨハネス・クレーマン, Johanesu Kurēman), or his alias and preferred name, Hans Lee (ハンス・李, Rī Hansu), is a half-devil, half-human hybrid. He is a rather carefree person, unbothered even by blood. By drinking controlled dosages every morning and evening, he has managed to almost completely control his bloodlust.
