The students of Class 2-A at Kamishiro High School have sworn a dark oath of revenge against their homeroom teacher, Takao Nanami. To destroy her, they orchestrate a cruel and elaborate scheme: staging a fake suicide designed to implicate her. One student is chosen to play the role of the victim in this deadly performance. However, the carefully constructed illusion shatters when the staged death turns out to be horrifyingly real. The sudden, actual loss of their classmate plunges the entire classroom into chaos and deep paranoia. As the shock settles, suspicion spreads like poison among the survivors. The students are left with one terrifying question—who turned the planned deception into a genuine murder by staining the water with blood? Stripped of all mutual trust, the bonds of friendship that once held the class together rapidly decay. In its place, a primal and desperate urge takes over, driving the fractured classmates to turn on one another as they struggle to sate a consuming hunger born from betrayal and fear.
