Code:Breaker Series by Akimine Kamijyo

THE DEATH DEALERS. Rei seems like an affable transfer student to everyone around him, but quirky high school beauty Sakura sees his true face as a terrifying vigilante—a “nonexistent” Code:Breaker who cannot be touched by the law. And since Sakura has just witnessed the effects of his deadly blue flame, she’s slated to be the next to burn!

As Sakura attempts to keep Rei from killing people, they are joined on a mission by Toki, another Code:Breaker. But under Toki’s affable exterior lies the heart of a ruthless executioner. And now all three of them are pitted against a politician with an army of guards and a deadly plan! Includes special extras after the story!
