Girls und Panzer centers on senshadou, a traditional sport in which World War II-era tanks are used in elimination-based matches. Practiced by women and girls alike, it is promoted as an art that elevates ladies in culture while appealing to men, and it has grown into a worldwide phenomenon, with a world championship soon to be held in Japan.
At the heart of the franchise is Miho Nishizumi, who comes from a respected line of senshadou specialists but has grown distant from the sport after a traumatic event forced her retirement and created a rift within her family. Hoping to avoid tankery as much as possible, she transfers to Ooarai Girls Academy, where the senshadou program has been abolished. But with the coming championships looming, the school revives its tankery program, and Miho is pushed back into joining.
With the help of new friends, she must confront her past, once again command a squadron of tanks, and fight to save her school from closure while proving to her family that the Nishizumi style of senshadou is not defined only by victory. Across Girls und Panzer, that balance of tradition, teamwork, and personal conviction remains at the core of its tank battles.
