Synopsis

Protagonist Ariga Mio is a powerful girl with a well-developed sense for justice and a fighting spirit that doesn't shy away from fights on school grounds.

Due to her misbehaviour, her parents who are concerned with their public image leave her no choice and force her to transfer to a school in the boonies that her younger brother attends. This is when she and her younger brother who had already been a wimp from very young age meet again.

As Mio comes to the student dorm to meet with her younger brother, she gets into a quarrel with the bossy Saotome Kanon. She's barely arrived and she already got into a fight.

The next day, she is ordered to the guidance room where she learns of the existence of the "Moral Discpline Club." Quickly, a group of bulky, strong men surround her, but Mio's conviction doesn't bend. However, for sake of "guidance" the bulky men grab her, push her down and forcefully deprive her of her virginity. Even getting gangraped by one man after the other, her fighting spirit doesn't lessen and her soul survives corruption for now.

---On the next day, however, it is not only the members of the Moral Discipline Club, but also the teacher and her classmates begin looking at her with disturbing, lustful eyes.

On these disturbed school grounds, with its extreme rules, Mio will now become victim to the males unleashed lust...
