Code:Breaker

Sakurakouji Sakura appears modest and graceful, yet harbors formidable martial arts prowess. Her world is shaken when she witnesses a boy burn people with a blue flame, only to discover that the same boy is the transfer student Oogami Rei. Oogami is a Code Breaker, one who does not exist. He presents as a seemingly cold-blooded killer who lives by an eye for an eye, using evil against evil. Convinced that killing is not right, Sakurakouji sets out to stop him and pierce the ice around his heart.
