The story takes place in a world where two countries, Arandas and Ingelmia, have been warring against each other for a very long time. Tokimune, a young man belonging to Independent Unit 8 of Arandas, saves a girl named Jamie when she is attacked by enemy forces. In order to survive, he pilots the new mech Argevollen and fights. The new mech Argevollen is defined by its U-Link system wherein the Argevollen molds to its pilot's mind and cannot be piloted by anyone else. This customization allows the pilot to envision what the mech will do in his mind to use it, rather than physically move and steer it.
