The forces of the evil Sword of Kusanagi have reached the gates of the kingdom of Amamikado, led by the possessed hero Kumaso. Amamikado's mighty general Ohiko manages to fend off Kumaso, but is ultimately betrayed and killed by his own king, Otarashi. The wicked king reveals his master plan-to destroy every soul in the land by using the holy sword himself. Before he can, however, Izumo and Oguna arrive, bearing the holy sword of Murakumo. They succeed in purifying the evil taint of Kusanagi, freeing its army of drones, not least of which is Kumaso himself. Now united once more, the three Takerus face down Otarashi and his enormous Doguma creation in a battle for the fate of the world.
