Dragon Ball Kai • S07E68 : And So, Ten Years Later...A Long-Awaited World Martial Arts Tournament!
Ten years have passed, and much has changed. Gohan has become a scholar, and Trunks and Goten are in their late teens. Goku is training with Goten when Bulma and Vegeta, who have a new daughter, Bulla, show up after not seeing him in five years. Goku says that he and Goten will be entering the World Martial Arts Tournament, so Vegeta says that he and Trunks will do the same.
