Kouichi's friendship with Mei seems to be one sided. He takes every chance he can get to speak to her, but she never seems to understand what he says. Her replies seem more cryptic as the days go by, and their classmates become increasingly suspicious.

Following Mizuno's bizarre accident, the tension rises in Class 3, and Izumi is chosen as the new Class Officer without Kouichi knowing. Rumors are spreading, but no one is willing to say anything.

A charm has been evoked by Class 3 for the past 26 years to ward off any further calamitous incidents. Kouichi begins to accept what's going on around him. However, he deems it unreasonable and begins spending more time with Mei.

Fresh blood is spilled, and Class 3 realizes that the curse hasn't stopped. The Charm rituals are called off. Everyone is on edge, wondering who among them is actually dead. Meanwhile, Kouichi learns of an incident 15 years in the past.

The casualty count continues to rise, and Kouichi's search for Matsunaga's tape is successful. During the class trip, the friends gather to listen, and to find out what Matsunaga did to stop the curse.

Chaos runs through the lodge hallways as students desperately seek the key to stopping the Class 3 Curse once and for all. Will Kouichi be able to find the answer before another victim is claimed?
