Ouritsu Ouji Gakuen (Royal Prince Gakuen, RPG for short) is a school where princes go in preparation of their future career as royalty. That means normal lessons, but also stuff like dancing lessons and other things you might need as royalty. Other than the fact that the entire student body are royal princes, it is a very normal school.
