|Realm of Nothingness|
|Rōmaji||Mū no Kai|
The Realm of Nothingness (無有の界, Mū no Kai; FUNimation "Null Realm") is a dominion of emptiness, devoid of time or space. It is an infinite nothingness, and as such, godly fighters such as Son Gokū can fight within this space without limitations. According to the Grand Priest, methods of flight are disabled within the Realm of Nothingness. It is also the location of the Tournament of Power.
It is later explained that the Realm of Nothingness can be controlled — though by who and what isn't stated, and the limitations for the Tournament of Power thought to be part of the World of Nothingness are in fact part of this control. A unique feature to the Realm of Nothingness is that it causes each individual to experience the gravity of their birth planet. Thus, no individual would have an advantage over another due to being accustomed to being born on a planet with stronger gravity.
