A foreign transfer student from the city arrives one day in a Japanese country town. Enchanted by his air of mystery, his classmates nickname him "Matasaburou the Wind Imp" after a local legend. Eventually they become friends and spend many days playing in the countryside. One windy day, Matasaburou returns to the city, leaving his classmates to speculate that he really was Matasaburou the Wind Imp and that he flew away on the wind.

In 1966, five infant children were kidnapped by an alien group known as the Alien Hunters for the Reconstructive Experiment Empire Mess, who wanted samples of humans from Earth to experiment on. The children were rescued by Mess' arch enemy, the Flash alien race, which took each one to a different planet of the Flash solar system for training. Each child was trained separately in a range of superpowers that will allow them to fight Mess, their bodies also adapted to the atmosphere of the Flash Solar System making them gain special abilities. When they finally return to Earth in 1986 to combat Mess, who is now trying to invade it, they use the opportunity to search for their birth parents.
