Riddle Story of Devil

A deadly school game forces an assassin to protect the very girl she's ordered to murder.

When Tokaku Azuma enrolls at the prestigious Myoujou Academy, she quickly discovers that the school’s elite façade hides a deadly game. She and eleven other girls are forced into Class Black, a covert assassin squad tasked with eliminating their own classmate, the gentle and unsuspecting Haru Ichinose. The prize for a successful hit is a wish granted without limit—any desire, no matter how impossible. Failure, however, means expulsion and a life stripped of purpose. The rules are simple yet brutal: each killer gets only one shot, and the target is off‑limits to any assistance. Instead of embracing the murderous contract, Tokaku finds herself oddly protective of Haru. As the other assassins close in, each armed with lethal skill and personal motives, Tokaku’s resolve shifts from killing to shielding. She becomes a reluctant guardian, using her own deadly talents to deflect attacks and keep Haru out of sight. The tension escalates as friendships blur, loyalties fracture, and the line between hunter and hunted dissolves. In this high‑stakes cat‑and‑mouse dance, the true battle isn’t just for a wish—it’s a struggle to preserve humanity amid a schoolyard of blades.

A class of teen assassins competes to kill one target, but the protagonist switches sides to protect her. Expect stylized action, yuri undertones, and dark backstories framed within a high-stakes game structure.
