Koakuma Kanojo The Animation

A cursed DVD is circulating through the school, and most people are smart enough to leave it alone. Mika is not most people. After watching it out of curiosity, she wakes up transformed into a succubus — wings, urges, the whole deal — and now has to get through her school day without anyone noticing she's basically become a supernatural creature of desire. That gets complicated fast when her crush Kazuya shows up, and her ability to stay in control starts slipping. The second episode shifts focus to Kana, another student who watches the same DVD after her friends dare her, and ends up dealing with a very different kind of transformation that her sister Mai tries to help her navigate. It's a short two-episode OVA with a supernatural hook that's more Ring than romance at first glance — the cursed media premise gives it a slightly eerie setup before it leans into its adult content. The character designs come from Hisasi, so if you appreciate that particular style, it's worth noting. If you've watched something like Kanojo x Kanojo x Kanojo and wanted a stranger, more supernatural twist on the genre, this scratches that itch. Fans of Yubisaki kara Honki no Netsujou who don't mind a weirder premise will also find familiar territory here. It's a quick watch that commits to its odd concept without overcomplicating things.
