Comedic OVAs that don't have much in the way of plot, but a huge amount of fanservice, to the point of being borderline-hentai. They also share a particular focus on large breasts. Kagaku na Yatsura goes much farther, though, both in breast sizes and ecchiness, only lack of visible genitalia distinguishes it from hentai.
