A hero from another universe on a mission to keep the peace of the cosmos. When 5 Dimensional Robots combine with him as the core, it becomes "Super Dimensional Robo, Daiyusha". The Dimensional Robos are all living machines with their own thoughts and wills, and can act on their own without a need for pilots to drive them. Along the way, the people of Cray, from watching these fellows throw themselves in harms way to protect the planet, gradually came to call them "Heroes". A hot-blooded soul born of justice is the greatest weapon. The shine of its "Justice Sword" forbids the existence of the evil that plagues people.
