However, she dishonored her family name, so she attends the no-name high school called Oorai, which doesn't have a Senshado club, wanting to stay away from it. But, the student council president has other plans, wanting to save their school from termination by winning the Senshado tournament.

Miho being ostracized soon after decides to leave Black Forest, and transfer to Oorai where she could just go to school and not worry about operating any more tanks in the near future. That is until the student council uses tactics to drag her back into Panzerfaren martial arts called Senshadou. At first Miho is not impressed by such dirty means, yet her new friends Hana, and Saori help her by calling out the councils bluff of expulsion. This had put Miho in a tight spot, and decides to join Senshadou to stop them from making too many mistakes.

Now enrolled into the tank division, she and her new friends train together to start up the marital art, which was once abolished by the Oorai academy. With new students enrolling left and right, the school's division begins to rise up out of the ashes to take on all new comers, and neighboring schools, which are floating carrier cities on the ocean itself.
