Synopsis:

High school student Shiina Shinya thinks all girls are pretty much good for nothing, just because he doesn’t understand them at all. This does not prevent him from being surrounded by strange girls, however! Tsubase Tooka, a pretty girl and admired by all, stalks him. Shikimura Masami, who is predominantly masochistic, has recruited Shinya into his gaming sessions. Ikari Satsuki seems oddly interested in all of these recent serial attacks and also seems to want to dip him into it. Banjou Yoruko, a rather quiet girl, decided that she and Shinya were bound by some fancy arrangement.

Uchida Yumeji, the school’s sleeping beauty, who spends all her time in the infirmary because she needs sleep very much. Shinya brings him the newspapers so that she can keep abreast of events during the short time she is awake. Then, Akane is convinced that she is a vampire. To everyone, Shinya thinks it might be real, but in practice, he lets her drink his blood anyway. How will Shinya fare with all these girls who are good for nothing and complicate his life?
