Based off memory. Also, spoilers. (Mature language possible) R-15 OVA might've just been an experiment or something- who knows. They took the original R-15 series and turned it into a magic thing. 10/10 story totally not sarcasm. Animation was the same as the original series Sound was still a nono. And the characters didn't really seem to do anything different. Except that ending... intruiging indeed.
