Kateikyoushi no Oneesan The Animation: H no Hensachi Agechaimasu

With his dad heading off on a business trip for the summer, Touya Sakura finds himself alone with four female tutors who move in to help him study. Rio handles language, Nagisa covers math, Sara takes on English, and Amane teaches biology. The setup is straightforward: a high school guy, an empty house, four attractive women, and a summer of 'intensive lessons.' You can probably guess where this is going. Adapted from a visual novel by Atelier KAGUYA, this two-episode OVA leans fully into its hentai genre without pretending to be anything else. Each tutor has a distinct personality and look — character designs by choco chip give everyone a different visual identity, so it never feels like the same character reskinned four times. The pacing moves quickly given it only has two episodes, spending just enough time on each tutor to establish who she is before things progress. The tone is light and uncomplicated. There's no dark twist, no heavy drama — just a playful summer premise done in a style that fans of Stringendo: Angel-tachi no Private Lesson or Discipline will recognize immediately. If you've seen either of those and liked the tutor or mentor dynamic, this hits a similar note. It's a short watch, the production is clean for its era, and it does exactly what it advertises.
