The year is 20XX. The ninja, who once forged the history of Japan, were scattered across the country during the Meiji Restoration. As these ninja mingled with the other clans, their bloodline thinned, and they gradually faded from sight. The descendants of these ninja clans, seeking to preserve their heritage, formed the WNA (World Ninja Association) in the hope of carrying on their legacy. And so it was that the WNA succeeded in developing Ninja-Gum, an art which could summon forth the strength of the Shinobi. And yet creating the most powerful Ninja-Gum requires the strongest of ninja DNA. So it was that the Ninjala Tournament was held, that the mightiest of all ninjas could be found...

Mitsuo encountered Superman, an alien who is a part of a federation that tries to maintain peace in the galaxy. He then received a helmet (that also serves as a mask) that gives superhuman strength, a cape that enables the wearer to fly, and a badge that allows him to breathe underwater and communicate with his fellow comrades whom he met soon after he utilized these gifts. Superman made it clear to all Permans that their identity must be kept a secret or their brain will be destroyed should it ever be revealed and they are given a special doppelganger robot that can replace them while they are away to achieve this feat, although it is not entirely foolproof nor is it free from potential problems. These equipments then allowed them to be young Permans who try to maintain peace and help the people who are in need.
