From Kotonoha:

Maki Takano and his three best friends Ryo, Natsume and Mei are students at a private academy for highly gifted children. Like all the other students of this isolated and heavily guarded school, they have never seen the outside world since they were brought to the school at the young age of three.

When a new female student named Kiriko Hinatsu arrives, Maki has the strange feeling that he has met her before. However, he seems to be the only person who can remember the girl. When he confronts her with his discovery, Kiriko reveals the unbelievable truth about their existence: The school they have been living at all this time is actually an experimental facility and all the students are but guinea pigs who are being used for sophisticated neurological experiments.

Maki now has to decide: Will he continue his false but sheltered life or will he help Kiriko escape even if that means putting himself and his mental health at risk?

Torn to pieces by a pack of dogs, young samurai Jintetsu's ravaged body has been found by Genkichi, outcast and master inventor. Genkichi gives the dead boy a new, indestructible steel body and a talking sword - just what he'll need to exact his vengeance. But what about Otsuki, the beautiful girl he left behind? Steel armor is defense against any sword, but it can't save Jintetsu from the pain in his heart.

In the middle of a high school assembly, all of the students suddenly collapse. The one behind it all is a girl named Mao who holds a grudge. She's out for revenge against the entire school!

Niwa, a college student of architecture, is moving into his deceased grandfather's house. He didn't know the man very well, but the house is conveniently close to school, and his grandfather was actually the architect who designed it. There's something unsettling about the house, though, and while he's wandering around, Niwa finds a mysterious old photograph of some girl who isn't his grandmother.
Later, he goes along with his friend Akira to take drawings of another old house that's going to be demolished. As he meanders through this old house, he has a somewhat supernatural and startling experience. Are these feelings and occurrences a result of the souls of the buildings themselves, as Akira suggests? Or is there some even deeper mystery to Niwa's uncanny experiences?
