Majisuka Academy(2010)

Majisuka Academy is a Japanese series following two transfer students at an all-girls school where violence and fighting define the social hierarchy. Atsuko Maeda arrives quiet and unassuming, while her classmate Onizuka Daruma is loud and confrontational—yet proves no match for the school's toughest gangs. When Daruma gets beaten by Team Hormon, Maeda's dormant fighting instinct awakens, and she defeats the attackers with ease. Her display of strength catches the attention of Rappapa, the school's most feared fighting group. Daruma recognizes Maeda's power and pledges loyalty to her, marking the beginning of an unlikely friendship forged through constant battles. As the two navigate Majisuka's brutal yankee culture, their bond deepens amid escalating confrontations with rival students and gangs.
