It is the year 336 of the Space Century on the planet of Sieren, and in the state of Innex, Flora Rain-who is blind-is employed at an elementary school. Flora is adored by her students, the principal of the school, and all the town's people, and enjoys a peaceful life in the town. By chance, she meets a strange youth named Locke. Locke has numerous superpowers, although he is very discreet about them and gives the impression of being an ordinary youth. One day, Locke is visited by a Military man, Major Caliann, who requests Locke's assistance in their investigation of Lordleon. Lordleon and his space pirates have attacked the enterprise Astoria Concern, but the chairman, Great Georg, didn't report the incident to the Union. The Union though this very strange, and decided to investigate Lordleon.

When the villainous Lady Kahn starts building an army of super-powerful espers, Colonel Ryu Yamaki is dispatched to recruit the most powerful superhuman in the known universe to help oppose her. Unfortunately, the esper known only as Locke has either never heard the "with great powers come great responsibilities" speech or he simply doesn't care, and he refuses to leave his peaceful civilian life herding sheep. However, when Lady Kahn makes a preemptive move to take Locke and Ryu out of the picture, the irritated superbeing quickly changes his mind. Now the bad guys are about to learn that starting a fight with someone with super powers that include teleportation, a nearly indestructible force field and space martial arts was a very big mistake!
