Kyouhei is a serious, responsible office worker? while his friend Mandayuu is anything but. A talented, high-strung, and perpetually horny hentai artist, Mandayuu is always getting Kyouhei mixed up in his hare-brained exploits. Whether it's posing for Mandayuu's comics or getting trampled by rabid fans at an anime convention, life with Mandayuu around is many things, but it's certainly never boring!
