Code:Breaker

Sakura Sakurakouji witnesses a boy killing people with blue flames, then finds him sitting in her classroom the next day. Rei Oogami behaves like an ordinary transfer student, but he belongs to a secret organization whose assassins punish criminals beyond the law's reach.

Refusing to accept his cold judgment of human lives, Sakura pushes into a world of extraordinary abilities and concealed orders. Her determination to stop him killing places her beside people whose motives and identities are far more complicated than they first appear.
