Futa-bu!!

Joining her high school's Futanari Club, Akane Niimura discovers a small group of four girls with a very specific shared trait and an unofficial agenda that goes well beyond the club's stated purpose of researching local festivals. The two-episode OVA follows the club on a trip to the Manra Valley onsen, where the hot springs have a reputation for certain... stimulating effects, and the research quickly becomes secondary to everything else happening. This is a short, lighthearted hentai from Studio 9 Maiami, adapted from a manga, and it leans fully into its niche. The Girls Love elements are central rather than incidental, and the futanari focus is the whole point — if that's not your thing, this obviously isn't for you, but if it is, the tone here is warm and playful rather than harsh or uncomfortable. Akane's perspective as the newcomer integrating into an established group gives it a loose character dynamic that keeps things from feeling completely disconnected between scenes. At two episodes, it's a quick watch with no real plot ambitions beyond what it sets out to do. If you've seen Futa-bu! Mix: Futanari World or Futa-Ane: Bitter & Sweet and enjoyed that corner of the genre, this fits comfortably alongside those. It's not trying to be anything more than a breezy, niche hentai OVA, and within those expectations, it delivers what fans of the genre are looking for.
