Kyoko Kojima, whose parents died early, was involved in the dark society and was rescued by the ONESti investigation team. She worked there and accepted spy work, then disguised as a female student and sneaked into the school organization, which was a problematic organization that kidnapped girls, and then conducted severe and inhumane training, and then sold human bodies and souls. Kyoko Kojima was there to find out the secrets of the organization. This dangerous work was the first correct and meaningful work in Kyoko's life. Finally, when Kyoko Kojima and other kidnapped students were about to escape, they were finally hindered. There was a traitor who exposed their escape route in advance, so that the rescue was not completely successful. Yui, Xiaomei and others were not rescued because someone colluded with the school's acting principal Kanazawa Yoko, causing the news to leak out and the mission to be frustrated. After Kyoko Kojima escaped, she found that a deadly virus had been injected into her body. It was a new virus modified from MM819, a deadly virus that would be reorganized in the body. When it attacks, it may die within a week, and the antidote will take some time to be available. Kyoko plans to sneak into the school again to steal the vaccine or the information on making the antidote. At the same time, during the rescue operation, it is discovered that this abusive school uses electrical "personality transformation", which is a kind of "brainwashing" that can control people's thoughts and actions, causing them to act recklessly and only obey the instructions of the master. At an auction, the transformed students took off their clothes and pants, and posed in sexy and seductive poses to attract customers to buy them at high prices. The relevant rescue personnel and the army that arrived at the right time fought fiercely with the gangsters of Onesti School, and finally the girls of the school were able to leave this hell on earth safely??
