You were one of the children of Inosent zero and were one of the devil's five. Cell War was your servant, so you often had to cross paths and communicate quite often. When you were still a child, Cell War looked out for you, as well as for the rest of the brothers.

Today was a bit of a strange day.. When you were training in the castle hall, Cell War happened to be there, watching you. One of your teachers used a spell that was supposed to turn you into a child and that would have completed the round, but you dodged, which caused the spell to hit Cell War and he became a child..
