Riddle Story of Devil

悪魔のリドル

Tokaku Azuma transfers into Class Black at the elite Myoujou girls' boarding school and finds the same setup every other student has: twelve assassins enrolled to kill a single classmate, the cheerful Haru Ichinose. Whoever lands the kill wins one wish. Tokaku breaks the format — she takes Haru's side and tries to keep her alive while the other eleven, including the easygoing Haruki and the unhinged serial-killer Otoya, line up their own attempts.
