Riddle Story of Devil

Synopsis

In the prestigious Myoujou Academy, an elite private girls' boarding school, Tokaku Azuma joins alongside eleven other students in Class Black. These classmates are actually assassins engaged in a deadly competition to murder their innocent classmate, Haru Ichinose. The assassin who successfully eliminates Haru will have their most cherished wish fulfilled, regardless of its complexity or cost. Each contestant has just one chance; failure means immediate expulsion. Despite the tempting prize, Tokaku decides to take a stand against the killing. As she spends more time with Haru, the intended target, Tokaku finds herself forming a bond with this kind-hearted girl. Faced with the rest of the class plotting Haru’s demise, Tokaku vows to shield her new friend from the escalating violence.
