The Coalition of Armed Associated Schools is a organization of schools bent on teaching young men and women the art of warfare to make them better leaders. Despite Shiho Nishizumi's thoughts, the Sensha-do federation allows to Coalition to remain active without interference due to their massive contribution monetarily to the Federation. However, after an accident with a Coalition and Federation school ship, tensions arise resulting in a painstaking war against the two organizations.
