STUDIO Huan (STUDIOふあん) is a doujin circle whose activity goes back to the print era, before digital distribution: the National Diet Library holds a 1998 contributor anthology and doujinshi from 2007 onward issued by the circle, and its books appear in the doujinshi rankings of Toranoana's Akihabara store from 2006. Its DLsite releases began in 2010. It specializes in school-setting works on the themes of hypnosis and pregnancy, resting on two pillars: the class-president line beginning with Iinchō no Saimin Natsuyasumi (2021), and the pregnancy-monitor line of Ninshin-gakari: Kariya-senpai to Ore no Haramase Ikkagetsukan (2022) and its sequel. Under the same name it also publishes the commercial digital comic Iinchō wa Saimin Appli o Shinjiteru., and posts work on pixiv and pixivFANBOX. By 2026 it had released 71 works on DLsite, with cumulative DLsite sales exceeding 150,000.
