Six months after his dad's remarriage, Naoto Takahashi is still navigating an awkward home life. His stepmother Sachiko and stepsister Yui feel more like strangers than family, and he can't figure out how to bridge that gap. Then one night he stumbles onto a mysterious app on his phone that lets him take over someone else's body — and yeah, this goes exactly where you think it does. This is a 2-episode OVA from 2017 by Studio New Generation, adapted from a manga, and it leans fully into its hentai genre. The body-possession premise gives it a supernatural hook that sets it apart from more straightforward entries in the category. There's a psychological edge to the setup — Naoto's using this power to navigate desires he can't act on as himself, and the family dynamic adds layers of tension that keep things from feeling one-note. If the body-swapping concept reminds you of Kimi no Na wa or Kokoro Connect, that's intentional — except this takes that idea in a very different, very adult direction. Think Yamada-kun and the Seven Witches if it dropped all pretense and committed to its most explicit implications. The animation quality is solid for what it is, and at just two episodes it doesn't overstay its welcome. If you're into supernatural hentai with an actual premise beyond the surface level, this one's worth a look. Just, you know, don't watch it in the living room.
