Siman, an alien who returned to Earth from Centaur, grants superpowers to his biological daughter Daily and the naive Hyung-rae with the purpose of justice and goodness, transforming them into Super Heroes. He then summons world-renowned scientists to create the wondrous, cutting-edge robot, Uraeme. Meanwhile, Marugi, the heir to the throne of the twin star Al, is injured by the space outlaw gang Luka and receives help from the Earth boy Myung-woo, but is captured by the relentlessly pursuing Luka. Consequently, Hyung-rae and Daily, led by Uraeme, infiltrate the villains' hideout. Luka uses an animal named Puppy and a hybrid human to push Hyung-rae and Daily into a crisis. At the moment of crisis, Uraeme appears, devastating Luka's advanced weaponry. Marugi returns to his home twin star with the help of Myung-woo, Super Hero Daily, Hyung-rae, and Uraeme.
