Cosplay Change: Pure-kei Joshidaisei no Kiken na Seiheki

For college student Aima Imoko, finding a costume shop near campus feels like a small miracle — especially for someone who takes cosplay as seriously as she does. When she steps inside, she meets the owner, a dedicated otaku who doesn't just sell the outfits but lives them. Two people this deep into cosplay culture, alone in a shop full of costumes, both willing to slip into character at a moment's notice — you can guess where that leads. This 4-episode OVA from Mousou Senka leans into the fantasy-meets-reality angle pretty deliberately. The premise is built around role-play as a form of self-expression, and it uses the cosplay setting as more than just window dressing — the costumes and the characters wearing them are genuinely part of the dynamic between Aima and the shop owner. The tone stays playful throughout rather than going heavy or dramatic. If you watched something like Futari Ecchi and appreciated how it used an ongoing relationship as its anchor, or if Resort Boin's mix of lighthearted setup and adult content worked for you, this covers similar ground with a cosplay-culture twist. It's adapted from a manga, so the story has a clear structure across its episodes rather than feeling like disconnected vignettes. Niche subject matter, but if that subject matter is already in your wheelhouse, the execution is solid.
