A middle-aged bachelor with a habit of using dating apps to hook up with younger women — specifically high schoolers — Katsuya is already in sketchy territory, but then things get genuinely complicated when he realizes one of the girls he's been chatting with is his own niece, Mifuyu. Yeah. That's the setup, and the OVA doesn't shy away from leaning into exactly how messy that situation gets. This is a PoRO production based on a visual novel, so you already know the production values on the character designs are solid — detailed and polished in the way their stuff usually is. The appeal here, if you're into this niche, is the tension between secrecy and taboo. It's not just scene after scene without context; there's an actual narrative thread pulling you through, with Katsuya and Mifuyu both navigating the fallout of that revelation. The dynamic between them shifts in ways that keep things from feeling static. If you've watched something like Kiken na Mori Onigokko or Notto Sexaroid Eurie and liked the way those handled darker relationship dynamics with actual story beats, this hits a similar note. Koushoku no Chuugi Kunoichi Botan is another one in the same ballpark tonally. It's provocative by design and doesn't pretend to be anything else — but if you're browsing this genre, the narrative hooks here are a cut above the usual.
