Akuma no Riddle: Riddle Story of Devil #1

This volume kicks off the action-packed manga series where a class of twelve assass-in students, each with a unique codename and skill set, is tasked with eliminating their target, the seemingly ordinary Haru Ichinose. The only one who can protect her is Tokaku Azuma, a fellow student who finds herself drawn to Haru and determined to solve the deadly riddle before anyone else can strike. Collecting the first part of the story, this edition sets the stage for a tense game of cat and mouse within the walls of Myōjō Academy.
