Otome ga Musubu Tsukiyo no Kirameki

Touya works at the residence of the Shijou family, one of the most prominent zaibatsu in the country, keeping an eye on and being of assistance to the lone daughter Ran. One day, it was decided that the free-spirited Ran will temporarily transfer to the Meigetsu Girls’ School.

Since everyone at the school, from its students to the staff, are female, it would be impossible for a boy like Touya to enter on a moment’s notice.
