After his grandfather's death, our main character (a male) is invited at a high-class school where the grandfather was the Director and owner of school. The school is actually a place to train girls to be sex maids for high politician and rich people. The main character accepted the indentation, not to rule over all the girls, but rather to find his childhood friend who was said to be at the school. When he arrives he is told he must defeat 7 top girls (by pushing them down and raping them) in order to be director, if he hopes to find any information on his childhood friend.
