A series of short stories centering on Sugekoma, a high school prodigy with severe behavioural problems, and Miss Matsuzawa, the teacher who he ties up all the time. It's a big send-up of S/M cliches, H manga, SF, and the otaku mentality. Nagano's art is at its most refined in this manga.

There are minor subplots concerning other students - e.g. Junko Fujieda, who can't stand perverts, they make her violent; and Murata, a masochist who's infatuated with her.
