Corpse Party - Blood Covered

It happened after school one rainy day… A group of friends have stayed behind to prepare for the next day’s school festival. One moment they are idly telling ghost stories but the next an enormous earthquake strikes and the entire school seems to fall down around them. They awake to find themselves trapped in a parallel version of their school. A school abandoned and disheveled and whose calendar dates back to 1927. Can they find a way out of this nightmare or are they doomed to the same fate that befell the other victims whose corpses that lie numerous throughout the school?

Corpse Party - Coupling x Anthology is a 145 paged Japanese anthology manga, primarily based off of Corpse Party, featuring a collection of random stories that does not follow any specific timeline.

It's about a group of high school friends in Kisaragi Academy. Kisaragi Academy was built on the grounds of Tenshin Elementary School, which was demolished after a string of disappearances and gruesome murders. After a mysterious earthquake, the students find themselves trapped in an alternate reality Tenshin Elementary School, where the murders of others trapped before them have continued unabated…

Based on the game of the same name.

The master of the school has an overwhelming power over the events that happen around the trapped. And that power is even greater on a certain day: her birthday.

By the same author as the renowned “Corpse Party”, Dolls Fall revolves around the lives of students at Jiaiin girls dormitory, an orphanage for middle school children without families. They are greeted with open arms by the matrons and other students, taught to accept their fellow orphans as sisters and the matrons as their mothers. Jiaiin is a safe haven for students, provided that they follow two simple rules: at night, lock your door and don’t leave the room, and never enter a matron’s room. Break either one of those rules and this series’ likeness to Corpse Party becomes evident.

There is a website for suicides appearing on the internet only at midnight and when certain specific keywords are searched. Although it is supposed to be only a mere urban myth, girls who have performed the ritual suddenly disappeared. High school paranormalist Naho Saenoki launches an investigation to shed light on this gruesome incident while the amount of victims keeps increasing.

With their school shutting down for good, the students of a small town were heading for different directions in life. For Minase Tamaki, who was staying in town to find a job, it might be the last time she sees her crush Shindo Yuuma, who is moving to the city to attend a new school. She asks him to do a little prayer that is supposed to help people cross paths again even if they become separated. But her classmate, Yuzuki Erina, overhears their conversation and, out of jealousy, decides to ruin her plans by inviting their entire class on what was supposed to be an intimate spell. As soon as the charm goes off, the ground splits in half, swallowing the entire class and, when they wake up, they find themselves in an old school campus. Unable to find a way out, they wander the corridors, trying to figure out where they are. But it seems that the building isn’t as abandoned as they thought it was and, in fact, something evil is lurking in the shadows.
