At Usama Academy in Japan, students from diverse backgrounds unite to cultivate talents in music, sports, sciences, and arts. The school is especially known for the Eight Turtles, a popular group divided into two factions.

The Swag Hamato Turtles excel in music and martial arts, captivating peers and teachers alike with their dynamic performances and rigorous training. In contrast, the Street Punks are community guardians, known for their edgy style and fierce loyalty as they combat local gangs. Their camaraderie has earned them respect both at school and in their neighborhood.

Their popularity has garnered them many admirers, especially from female students. However, excitement turns into apprehension when they learn they’ll participate in an exchange program to Ishimma High School in New York, notorious for its troublemaking reputation. As they prepare to leave the comforts of Usama Academy, the Eight Turtles face uncertain dynamics in their new environment.

Now at Ishimma High, the Usama Academy students, bags in tow, await class and dorm assignments.
