Riddle Story of Devil

悪魔のリドル

Tokaku Azuma, a trained assassin, transfers into an exclusive boarding school's Class Black: thirteen students, twelve of them killers competing for a single wish, all aimed at the thirteenth, the endlessly friendly Haru Ichinose. Assigned to eliminate Haru, Tokaku instead finds herself drawn to protect her from the other assassins circling the classroom, while the question of why Haru was marked at all hangs over the shifting loyalties inside Class Black.
