In this sequel to Majisuka Gakuen 5, they take the alternate events where the Majisuka All-Girls High School goes bankrupt. In order to save their school from shutting down, the girls decide to open a hostess bar called "Aquarium".
Majisuka High is an all-girls school that is full of delinquents and is constructed of dysfunctional classrooms that have no discipline whatsoever. There is constant physical fighting within the school walls sprayed with graffiti, and students take naps on the littered floors of the school. But here in this jungle, a group of girls called the "Rappapa" are the claimed leaders as they have won their position by fist. Being the strongest in fist-fights is indeed the social currency at this deteriorating school. The leader of the Rappapa pack is Salt; she reins as the queen of the chaotic hierarchy. But one day, a new student, Sakura is transferred to Majisuka High with an aim to overthrow Salt and take over the school. On first glance, she looks like a student who would make the honor roll, vulnerable, and easily beatable. Yet, when the second year groupie, Team Hinabe, pick a fight with her, they find out that she is someone who should not be trifled with... at all! ~ NTV
