BUTTOBI!! CPU is an ecchi anime with actual sex in it. That statement may seem a tad odd but for naughty content most anime either go lukewarm (e.g. "plot" bouncing everywhere, panty shots, bizarre fetishy nonsense that turns off even the most tolerant viewers who aren't into it) or hardcore porn. For an idea of the content in untranslated pages, visit these urls: https://www.animenewsnetwork.com/encyclopedia/anime.php?id=125 https://myanimelist.net/anime/458/Buttobi_CPU https://nyaa.si/view/1285823 (partly because the dialogue I left untranslated is taken from the anime. I know one line is exactly quoted. others may be paraphrased, though I didn't check.) themes: aggressive female (more like insatiable...), robot girl (sort of. She's a "bio-type computer.")
