Kateikyoushi no Oneesan 2 The Animation: H no Hensachi Agechaimasu

With his parents gone for the summer, Touya somehow ends up with four different female tutors living under his roof — each one assigned to a different subject. Rio handles languages, Nagisa drills him on math, Sara covers English, and Amane takes care of biology. What starts as a straightforward cram session setup turns into something considerably less academic. This is a two-episode OVA from 2010, based on a visual novel, and it leans fully into the harem tutoring premise without much pretense. The tone is light and comedic between the explicit scenes — there's actual personality given to each of the four women, and the character designs are distinct enough that they don't blur together the way some entries in this genre tend to do. The animation holds up reasonably well for its era. If you've watched something like Boku no Yayoi-san and appreciated a setup that gives you a handful of different character dynamics rather than just one, this follows a similar approach. Fans of Oni Chichi who want something with a slightly more playful, low-stakes atmosphere might find this a comfortable watch. At two episodes, it doesn't overstay its welcome. It knows exactly what it is — a short, easygoing adult OVA built around a familiar premise — and it delivers that without padding. Go in with matching expectations and it works fine.
