Kakyūsei

Kakyūsei (下級生) is a dating sim series by ELF Corporation originally created by Masato Hiruta, as a spin-off of the Dōkyūsei series. An anime OVA based on the first game, Elf-ban Kakyūsei (エルフ版　下級生), was created by Pink Pineapple. The title distinguishes the anime from the similarly titled but unrelated OVA series of the same title, Kakyūsei, also produced by Pink Pineapple, but earlier, in 1995. It had a TV series produced after the success of the OVA. The 14th episode of the TV series was never aired on television. A television series based on Kakyūsei 2 game was also released, as well as OVA sequels and spin-offs based on Kakyūsei 2, that were considerably more explicit than the TV version.

Plot
The story revolves around Mizuho Yuuki, whose best friend Miko has fallen in love with Tohru. Miko is fairly innocent and comes from a strict background so Mizuho tries not to get in the way of their relationship despite her growing awareness of Tohru who is currently boarding with her family, and accepts going on a date with the wealthy Haruhiko. There is also outside interference from Ai, a younger student in their school, who also likes Tohru.
