Bulma, a headstrong 16-year-old girl, is on a quest to find the mythical Dragon Balls—seven scattered magic orbs that grant the finder a single wish. She has only one desire in mind: a perfect boyfriend. During her journey, Bulma encounters Gokuu Son, a powerful orphan who has known only one other human besides her. Gokuu possesses one of the Dragon Balls, which serves as a memento from his late grandfather. In exchange for it, Bulma invites Gokuu to accompany her on her travels. By Bulma's side, Gokuu discovers a world completely alien to him. Powerful enemies pursue their own quests for the Dragon Balls, pushing Gokuu beyond his limits as he strives to protect Bulma and their growing circle of allies. However, Gokuu harbors secrets unknown even to himself; the incredible strength within him stems from a mysterious source, one that threatens the many people he grows to hold dear. As his prowess in martial arts flourishes, Gokuu attracts stronger opponents whose villainous plans could collapse beneath his might. He undertakes the endless venture of combat training to defend his loved ones and the fate of the planet itself.
