Trained her entire life to try and kill the Spirit that killed her parents, joining the AST, and after a series of incidents, DEM to try to kill that spirit.
After joining DEM, she uses a new CR-Unit in battle only to lose. She wishes for more power and inadvertently becomes a Spirit herself. She travels back in time to try to kill the Spirit of Origin, because she believes the Spirit of Origin killed her parents, but the killer was actually Origami herself. This is the reason for Origami to invert.
