In the near future, the sports world is dominated by Neo Wrestling, a new spectacle in which Metal Fighters challenge each other to be named champion. The story follows the girls of the Pretty Four; Miku, Ginko, Sayaka, and Nana, as they face off against the current champions, Team Sapphire. With a burnt out drunk named Eiichi Suo for a coach the girls must not only contend with problems in the arena but also unforseen circumstances that arise in day to day life.
