It is the first Dragon Ball anime produced in 18 years and is set after the defeat of Majin Buu, when the Earth has become peaceful once again.

One night right before summer vacation, Daichi Manatsu, a second-year in high school, sees a weird round rainbow floating in the sky above Tanegashima and ventures there alone. He has seen this rainbow before. With the memories of his father's mysterious death and an encounter of a mysterious boy and girl, Daiji arrives on the island while the alarm of a building labeled "Earth Engine" is going off. Someone asks him if he's a captain, just as robotic intruders from Uranus called "Kiltgang" arrive. The battle around the shining stars is about to begin.

The Earth's Greatest Warriors are back in Dragon Ball Kai, an HD Remaster and Recut to commemorate the 20th Anniversary of author Akira Toriyama's hit anime Dragon Ball Z. Using Dragon Ball Z's footage, the series has been remade in high definition and recut, removing most traces of filler for the sake of a faster pacing, sticking closer to the original manga work.
