A studio crowded with old dolls is the perfect place for Mei to tell Kouichi the tale of three students' mysterious deaths 26 years ago. Finding out more information from his classmates proves difficult, but his aunt Reiko is willing to tell him more.

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.

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?
