2) Gekkouchou ~Hyaku-nen no Koi~: A two-tailed tiger-striped cat is taken in by a girl called Mitsu and given the name Torakichi. Torakichi is no ordinary cat, and the love and tragedy between them may be strong enough to transcend a simple lifetime.
3) Friend Doll: Mizuno Sachi spends almost all of her time studying, thanks to her demanding parents, and she doesn't really have friends.

But what is Mimi's motivation for all this help?
4) Tonari no Yomi-san: There's an urban legend about a girl who killed herself as a teenager, "Yomi-san," due to her insecurity over her appearance. Supposedly, her father stuffed her body, and, in her quest to become beautiful, the body seeks to take parts from pretty girls. At one school, several pretty girls have been mysteriously injured. Could the culprit be the dead girl, Yomi-san?
5) Oni no Sumu Shima: Saki moves out to a rural area, where she has no friends. In her loneliness, she goes out to an uninhabited island, where she meets a new possible friend. He's a demon, but as Saki gets to know him, she finds him less and less frightening...
