In the prestigious halls of Kunugigaoka Junior High, reputation is everything. For Y/N, a girl with ethereal beauty and a mind as sharp as a chef's knife, life was sweet-until a false accusation of cheating stripped it all away. Relegated to the "End Class" on the mountain, she expects a life of isolation. Instead, she finds a yellow octopus teacher, a classroom of assassins, and a red-headed devil named Karma Akabane. ​Karma is brilliant, bored, and loves nothing more than a reaction. When he discovers that the class's new "Angel" has the temper of a demon and a vocabulary of a sailor when provoked, he makes it his mission to bait her. Between assassination missions and cutthroat exams, a rivalry ignites that sets the mountain on fire. But in the world of Class 3-E, the line between a killing blow and a heartbeat is thinner than it looks.
