Hininden Gausu (緋忍伝-呀宇種（ガウス）) is a 2005 hentai anime OVA series.It’s the first anime directed by designer Rin Shin who has worked on this project for years despite warnings that a historical drama in hentai would not work. And effectively and in spite of high production values the first episode sold poorly putting Pink Pineapple in the red for several months after the release. Plans for future episodes were dropped and Studio Arms no longer works in the hentai field.
