Kouichi Sakakibara arrives in Yomiyana and becomes friends with a quiet girl with an eye patch.

Kouichi's friendship with Mei appears to be one sided and their classmates suspect something.

After Mei tells Koichi the story about a mysterious student death years earlier, none of his classmates are willing to talk about it. It's his own aunt Reiko that tells him that his late mother was in that same class!

The curse rumour grows with the accidental death of a student; the head of countermeasures begins an investigation of Class 3.

Tension rises in Class 3 after Mizuno's accident and a new class officer is chosen.

A charm wards off any further calamitous incidents; Kouichi begins to accept what's going on and spends more time with Mei.
