In a world like our own, Sensha-do, the art of tank combat or ‘Tankery’ for short, is a traditional Japanese martial art for girls. In every school there is a Tankery Club. Miho Nishizumi, a girl who has a long and proud family history in the art of Tankery, has just transferred into Ōrai Girls’ Academy in Ibaraki Prefecture…to avoid Tankery! The school’s Tankery club is believed to have been non-existent for 20 years! As Miho made new friends and enjoyed the start of her new school life in Ōrai Girls’ Academy, she is suddenly ordered by the student council to revive the school’s dead Tank Club and be their leader. Giving in to the pressure from the student council and her friends, they form the Tankery Club, marking the start of a formidable tank force.
