The journey to the martial peak is a lonely, solitary and long one. In the face of adversity, you must survive and remain unyielding. Only then you can breakthrough and continue on your journey to becoming the strongest. High Heaven Pavilion tests its disciples in the harshest ways possible to prepare them for such a journey. One day the lowly sweeper Yang Kai managed to obtain a mysterious black book, setting him on the road to the peak of the martial world.

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.
