When a friend's business crashes and burns and he vouches for the debt, a middle-aged guy finds himself drowning in debt and gets handed a bizarre lifeline: a job at Seika School, an elite all-girls academy that grooms its students into refined, picture-perfect young women. Dating is strictly forbidden on campus. The problem is, forbidden doesn't mean gone, and the school has a very unconventional solution to that tension. They hire men. Officially sanctioned, discreetly employed men. Our protagonist, desperate enough to not ask too many questions, takes the job. What follows is him navigating this strange institution and its cast of very distinct students — including a soft-spoken girl named Tomoe, an athletic type named Mio, and the student council president Louisa, who runs the place with confidence and a lot of presence. The setup is essentially the collision between a buttoned-up institution's rigid expectations and the reality of the people living inside it. T-Rex's animation keeps things polished, and the character designs actually reflect personality differences rather than just being interchangeable. If you've watched something like Discipline: The Record of a Crusade or Stringendo: Angel-tachi no Private Lesson and appreciated when a hentai OVA at least puts some effort into its premise and characters, this six-episode series is in that same space. It doesn't reinvent anything, but it's put together well and the scenario has enough going on to keep it from feeling hollow.
