俺がお嬢様学校に「庶民サンプル」としてゲッツされた件

Kimito Kagurazaka, an unremarkable high school boy, is kidnapped and enrolled at Seikain Girls' Academy, a school so sealed off from the world that its students have never seen a cellphone. The staff presents him as a commoner sample meant to acclimatize the girls to life outside, and to keep him harmless in their eyes they spread word that he is attracted to muscular men. The first to approach him is Aika Tenkubashi, an heiress who builds a Commoner Club around him.
