Oushun Jogakuen no Danyuu

Oushun Jogakuen gathers daughters of old houses and political families. Scandal is career-ending, so desire does not vanish—it is managed in secret. The protagonist is hired as a janitor. That is the cover. His real work is to act as each student’s “ideal man,” a role the school calls danyuu.

His first assignment is Ichijou Saeki: student council president, academically and socially unmatched, born into a line that has already produced a prime minister. In public she is the person others stand behind. In private she needs the opposite—someone who will take the lead and stay in character as her master.

The series is adult hentai built on prestige-school hierarchy: uniforms, family names, and the gap between the girl the academy displays and the girl who can only speak her fetish when the door is locked. Episode 1 (split edition, 24 pages in the source doujin) sets the rules of the job, Saeki’s status, and the first performance. Later chapters move to other students, but this opening is about one contract: he must play master so the student president can stop performing perfection.
