"Think of it as a ladder. On the bottom rung is all of space. Higher up is Hell and then Snake Way. At the next level are the planets of the four Kais who oversee their parts of the universe. And higher still, above the four Kais and all the rest is the Grand Kai's planet."
Olibu in "Tournament Begins"

DBUniverse (SuperExcitingGuides)

The Dragon Ball series is set in a different universe (宇宙, Uchū) from our own. The main hero of the series, Goku, uses his incredible strength and sense of good to combat the evils that plague all around this universe.

Contents and structureEdit

In Daizenshuu 4, Daizenshuu 7, and the Super Exciting Guides, Akira Toriyama himself explains that he envisioned the Dragon Ball cosmos as a big ball. This "ball" is divided up in two halves: the realm of the living (or "The Universe") and the Other World (or "The Cosmos"), with Hell located between the two halves.

The realm of living is divided into four Quadrants, each ruled by a Kai chosen among the Shin-jins from Planet Kaishin. There is one Check-In Station for the four Quadrants of the universe, which allows its inhabitants to go to the Other World. The Kais live in the Other World, on planets located on the four sides of the cosmos; notably, North Kai's planet is at the end of a Snake Way which starts from the Check-In Station. The Grand Kai's planet is above Heaven, which is a gigantic planet in the center of the cosmos.

The planet of the Kaioshins, the top-tier deities of the universe who watch over both the Other World and the living world,[1] is located outside of the ball, in the Sacred World of the Kais. The Demon Realm, where the Makaioshins (the complete opposite of the Kaioshins) live, is located on the very bottom pin/tip shaped of the universe.[2]

Places in the universeEdit

  • In the video game Dragon Ball Z: Buu's Fury, Grand Kai's planet is located outside of the ball, below the Sacred World of the Kais.
  • Toriyama said that the structure of the cosmos was so that it would be easy for both him and the readers to understand.[2]
