The other 11 are scattered between the 2 dimensions and they must go in search of those celestials to unify the Grand Gailore Council in hopes of establishing peace throughout the universe. Suddenly, an evil lord by the name of Hades captures the celestials one by one, slowly crushing the shared dream the celestials had. War breaks out soon and the Gemini Twins must be prepared. What will happen to the fate of the world?
