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. Only through protecting their friends, understanding their enemies, and eventually challenging their idol Aquamarine, can Miku and the girls understand Eiichi's purpose and the shady secrets behind Neo Wrestling.
