Prison school episode 12
"Good Morning, Prison"
Chiyo waits at the back door of the Corrections Office, where Kiyoshi and Hana's confrontation is taking place. As Hana goes in for another kiss, Kiyoshi counterattacks by sticking his tongue inside Hana's mouth, completely shocking the sexually pure Hana and resulting in a profuse nosebleed. She leaves the Corrections Office, and Chiyo comes inside. As Kiyoshi returns to the prison, Hana allows Gakuto and Joe to use the bathroom, before the five head off to bed. Suspicious, Mari and Meiko proceed to patrol the prison, before declaring it inescapable. The next day, Meiko takes the boys to the Chairman's office. Meanwhile, Gakuto runs inside the school, causing the schoolgirls to beat him up. As Kiyoshi declares that they themselves have won, Meiko catches on to their ruse and grabs Joe disguised as Gakuto, and Chiyo disguised under Joe's hood. Gakuto is thrown into the Chairman's room by the students. Then the boys explain that Chiyo sneaked in from the back door of the Corrections Office, where she met with Gakuto and Joe inside the bathroom, performing a three-way exchange with each other's clothes. Under disguise, Gakuto made his way to the Corrections Office, enduring his cut from the fork to have Joe disguised with the use of bandages. Gakuto hid himself outside while Mari and Meiko were patrolling. When Meiko expresses disbelief at how fast the DTO email would have been recovered, Gakuto tells her of the data restoration software being downloaded ahead of time during the arm wrestling match. As Gakuto passes the DTO's information hardrive to the Chairman, Hana discovers Kiyoshi's manipulation and proceeds to punch him, only to punch Mari instead, who wholly confesses to the DTO plan.
In a post-credits scene, while the boys seem content outside of their prison lives, the prison-clad USC make their way to the school prison. They are charged by the Aboveground Student Council (ASC). News about their abusive incidents have been spread around the school.
