Dragon Ball GT: Revenge of the Zful Planet

Based on the GT Bebe chapter, in addition to the plot, there will also be some modifications to the settings. If there are any shortcomings, I hope you will correct me. The story takes place in a world 10 years after Dragon Ball Z. Before the ancestors of the gods and Demon King Piccolo separated, he created the Black Star Dragon Ball. Whenever it fulfills its wish, the Black Star Dragon Balls will be scattered throughout the universe. If the seven Black Star Dragon Balls cannot be gathered together within a year, the planet that originally made the wish will be destroyed by itself. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
