Koba Kensuke

Of the 9 people, who is it okay to die - who should die? Shuichi visits an underground building deep in the mountains with his club friends from the university. They accidentally wander into an underground building with a family of three and spend the night there, but an earthquake occurs in the middle of the night, blocking the door and causing water to pour in from underground. To escape, one person must stay behind. Then a murder occurs, and if the culprit is not identified, they would all be dead. The brutal search for the culprit, with a time limit of about one week, begins! Based on the novel written by Yuuki Haruo.

At first, it seemed like an ordinary day at Yami High. But it wasn't. A ringing cell phone and the splatter of blood marked the beginning of a deadly game. The rules: Contractor Mikiya has thirty days to curse-kill thirty people or meet a fate worse than death. On the other side, Curse-Breaker Saeyama must identify the killer without falling prey to one of Mikiya's curse-kills. Only time will tell who will emerge victorious.
