Ore ga Ojou-sama Gakkou ni -Shomin Sample- Toshite Rachirareta Ken

Deep in the forest-covered mountains is an all-girls school, attended by children from only the richest and most prestigious of families. Here, the girls are raised to be perfect young ladies, cut off from the real world to preserve their innocence and ensure that they're free from all distractions. This policy of isolation is a double-edged sword, however, for after graduation, students of the academy often struggle to adapt to a world that's totally different from their cloistered school life.To combat this inevitable culture shock, an average teenage boy, Kagurazaka Kimito, is kidnapped by the school to provide its students with knowledge of the outside world. Forced to enroll against his wishes, Kimito must now attend classes in a place where his very manhood relies on keeping the girls happy. Can one regular guy possibly survive in a fearsome, all-female student body?
