School x Fight

Mirai is willing to fight to protect other people. After she defeats thugs attacking Ryo, her school’s idol, she is promoted from the ordinary class 3 to class 1, the top class. When Mirai later defends a girl from the lowest class, class 0, against class 1’s arrogant students, she says she wants to leave the two-faced top class. Instead, she is expelled from class 1 and downgraded to class 0, where she joins the girl she defended and a mysterious black-haired boy she met earlier. Now the real fight begins.
