"Senshadou" is a traditional sport that uses World War II-era tanks in elimination-style matches. It is widely practiced by women and girls alike and is advertised as a form of art designed to make ladies more prominent in culture and appealing to men. Over time, it has become a worldwide phenomenon, and its influence has led to the creation of a world championship that will soon be held in Japan. Miho Nishizumi, who comes from a lineage of well-respected senshadou specialists, is at odds with the sport after a traumatic event led to her retirement and eventually caused a rift to form between her and her family. To steer clear of the practice as much as possible, she transfers to Ooarai Girls Academy, where the senshadou program has been abolished. However, with the news of the upcoming championships, the school revives its tankery program, and Miho is pushed into joining. Now, with the aid of some new friends, she must overcome her past and once again take command of a squadron of tanks in an effort to save her school from closure, all while proving to her family that the Nishizumi-style of senshadou is not solely about victory.
