Kangoku Gakuen ~ Prison School (2015) [J-Drama] (Ep 09 END)

Hachimitsu Academy, a former private boarding school for girls which has become a co-ed school and boys can enroll too. However, Fujino Kiyoshi is one of only five male students who enter the academy. He and the other boys Morokuzu Gakuto, Wakamoto Shingo, Nezu Joji and Ando Reiji are excited by the prospect of an indulgent campus life with more than 1,000 female students, but they keep getting cold looks directed at them. They cannot even speak to the girls directly and lead agonising lives. One day, Kiyoshi promises to go together with a classmate Kurihara Chiyo to watch amateur sumo because of professional sumo writing material that his mother made him have. He is in high spirits, but ends up being imprisoned by the beautiful three-member underground student council which controls the school, as punishment for attempting to peep into a female bathroom with the rest of the guys. They are forced into a one-month confinement in a prison called the “discipline building”. Even so, Kiyoshi and the rest are undaunted and try to break out of this prison with all sorts of methods. However, the chairman Kurihara Mari, deputy chairman Shiraki Meiko and even the secretary Midorikawa Hana of the underground student council attempt to corner them into dropping out of school. Will the five boys be able to escape from prison successfully without yielding to the rule of the council?
