Tsukiyono Omi
Omi lived most of his life with no idea who he truly was. Omi was found by the founder of Weiß Kreuz as a child, with no memory of his past. His name, age and family were mysteries to him.
Omi found a new home with Weiß Kreuz. Trained from childhood to be an assassin, he probably deals with the hardships of being an assassin far better than the other members of the team. However, his young age can make him vulnerable to manipulation at times.
