Dragon Ball GT: Gokuu Gaiden! Yuuki no Akashi wa Suushinchuu

A century after the adventures of Goku and his companions, elderly Pan raises Goku Jr., a timid descendant who bears a familiar name but little of his legendary ancestor's courage. When Pan suddenly falls gravely ill, the boy remembers the stories of the Dragon Balls and sets out for Mount Paozu, convinced that the four-star ball once treasured by Goku can save her.

The journey forces Goku Jr. beyond everything he fears. Joined unexpectedly by his school bully Puck, he faces monsters, danger, and loss while discovering a strength he never knew he possessed. At the end of the road, an encounter with his famous ancestor teaches him that courage is not something inherited through blood; it is something proven when another person needs you.
