Vengeance Is Hana's.Shingo becomes an informant to the USC in exchange for above-average prison food. After Andre knocks down Joe's ant farm by accident, which results in Joe getting aggressive towards him, Shingo relays this information to Meiko. During lunch break, Shingo lures Joe away from watching his ants, where one of Mari's crows appear to smashing his ants. As Joe realizes this, he attempts to stab Mari with a tree branch, when Kiyoshi pushes him aside before impaling himself in the butt. While Joe is thrown in solitary confinement, Kiyoshi goes to the nurse's office with Hana. Hana hands him a pail to urinate inside, but after refusing to, she decides to do it on him instead. However, Chiyo arrives inside, so Hana and Kiyoshi hide under the bed, where with their lower half exposed, Kiyoshi's penis starts poking at her, and Hana faints. Later, Joe is released, and Hana seems to have no recollection of the events that went on in the infirmary, although Kiyoshi has no idea of her not knowing. After work break, where Kiyoshi and Joe made amends, Kiyoshi talked about Shingo and Meiko's conversation. Meanwhile in the Corrections Office, Meiko tells Shingo that she will allow him free time outside of school.
