After bravely perishing in battle against the monstrous Jave, the mightiest warrior of mankind is reborn as an infant. Now, thirteen years later, as the Jave threat resurfaces, Okegawa Kuon joins a specialized academy teaching combat with magic-enhanced suits called Division Maneuver. Initially limited to the weakest Division 1 suit due to low magical prowess, Kuon's fate changes when a unique, extraordinary suit becomes available, capable of activation even with minimal magical abilities.
