Underground Student Council In Prison School

The Underground Student Council is a fictional organization in Prison School that enforces the traditional rules of the school code of Hachimitsu Academy. Though a vigilante organisation, they enjoy more student popularity than the official Student Council. Here are the three of their members:

Mari Kurihara 

Mari is the president of the underground student council. She is the daughter of Hachimitsu Academy's chairman and the sister of Chiyo. A cold and calculating figure who seeks to uphold the school's traditions and rules. From the very beginning she immediately despises the boys, and the chairman's decision of integrating the academy. Much of this stems from her own resentment of her father's perverted behavior. In middle school, Mari helped Meiko stand up for herself when she was bullied by Kate, and the two have remained close friends ever since. She, like the rest of the Kurihara family, employs a strange philosophy to judge one's character. Her philosophy is, "Anyone who likes crows isn't all bad."

Meiko Shiraki

Meiko is the towering bespectacled vice president of the underground student council. She is put in charge of watching over the boys while they are in prison. In middle school, she was bullied for her large breasts. The strongest student in the school, and proficient in Judo, Meiko is a harsh disciplinarian over the boys, and often punishes them for the slightest infraction, with Gakuto being a popular target. Although a powerful and intimidating figure, she deeply fears displeasing Mari, which manifests itself in body-wide excessive sweating. Similarly, she enjoys performing calisthenics, and is often seen comically performing odd exercises with a large puddle of sweat underneath her. Aside from working out, she has been shown to have a knack for cooking. Because of her voluptuous/athletic physique, her school uniform barely manages to hide her body often leading to comical wardrobe malfunctions.

Hana Midorikawa

Hana is the secretary of the underground student council. She mostly ends up in the worst situations with Kiyoshi, whom she eventually develops feelings for. She is also an adept martial artist, often utilizing her karate skills to brutally punish the boys if Meiko's harsh punishment doesn't work. Although she seems composed and competent, she is actually incredibly childish and understands little of boys or and fails to adapt to situations she does not expect. After her release from prison, she acts as Mari's spy for the Above Ground Student council.
