Having been raised by the kindly monster Brass, Dai's dream is to grow up to be a hero. He gets to become one when Hadlar is resurrected and the previous hero, Avan, comes to train Dai to help in the battle. But Hadlar, announcing that he now works for an even more powerful demon lord, comes to kill Avan. To save his students, Avan uses a Self-Sacrifice spell to attack, but is unable to defeat Hadlar. When it seems that Dai and Avan's other student Pop are doomed, a mark appears on Dai's forehead and he suddenly gains super powers and is able to fend off Hadlar. The two students then go off on a journey to avenge Avan and bring peace back to the world. (Source: Anime News Network)

Dragon Ball

Goku Son is a young boy who lives in the woods all alone—that is until a girl named Bulma runs into him in her search for a set of magical objects called the "Dragon Balls." Since the artifacts are said to grant one wish to whoever collects all seven, Bulma hopes to gather them and wish for a perfect boyfriend. Goku happens to be in possession of a dragon ball, but unfortunately for Bulma, he refuses to part ways with it, so she makes him a deal: he can tag along on her journey if he lets her borrow the dragon ball's power. With that, the two set off on the journey of a lifetime. They don't go on the journey alone. On the way, they meet the old Muten-Roshi and wannabe disciple Kuririn, with whom Goku trains to become a stronger martial artist for the upcoming World Martial Arts Tournament. However, it's not all fun and games; the ability to make any wish come true is a powerful one, and there are others who would do much worse than just wishing for a boyfriend. To stop those who would try to abuse the legendary power, they train to become stronger fighters, using their newfound strength to help the people around them along the way. (Source: MAL Rewrite)
