Prison School | | The story takes place in the private Hachiko Academy located on the outskirts of Tokyo. This school is dedicated to cultivating noble and pure daughters and is famous for it. However, what everyone cannot believe is that since April 2011, this temple, which has never been visited by men, has begun to recruit boys, and five boys headed by Fujino Kiyoshi (played by Daishi Nakagawa) have become the first batch of male students in the history of this school. Instigated by Zhuge Yue Ren (Eramoto Tokio), Wakamoto Shingo (Yano Seito), Andre (Sakamoto Yusuke) and Nezu Joji (Miyagi Daiki), Fujino Kiyoshi decided to go with them to spy on the women's bathhouse. However, the four people who were quickly arrested were of course punished by the "Urban Student Union", a mysterious organization within the campus. They were imprisoned in a "prison", and every day they were "tortured" and "ravaged" by the president Li Yuan Wanli (played by Yamazaki Huna) and other backbones of the student union.
