事件の真犯人は、事件唯一の生存者だった…。そして苦難を乗り越え、友との再会を果たすが――!?　呪いはさらに生者を深い闇へと誘う、驚愕の第七巻登場。

A stormy night. A harmless ghost story. A silly pact intended to symbolize their friendship. But before the students of class 2-9 at Kisaragi Academy even know what's happening, they've been swept up in a living nightmare that threatens to consume them all. When the spirits emerge, will even their friends be left to hear them scream...?

The pact meant to keep them "together forever" has only driven them further apart. The bodies start piling up as the murderous Tenjin Elementary School takes its toll. For the students of Kisaragi Academy's class 2-9, not only life and limb are at stake, but also their very sanity as the curse slowly eats away at them. It's a race against the clock to discover the secrets of this bloody school before all that remain are corpses. When the screams stop, will anyone be left alive?

"We'll be together forever...in death." As the body count rises, a few tearful reunions mark the only bright spots in the hellscape that is Tenjin Elementary School. The child ghosts from the gruesome murders thirty years ago have a tight grip on the school, but if the remaining students of Kisaragi Academy's class 2-9 can put those souls to rest, they might have a chance of escaping this death trap! When hope is hanging by a thread, what will it take to make it snap...?
