Astral World (アストラル世（せ）界（かい） Asutoraru Sekai) is the dimension where Astral was born and a location in Yu-Gi-Oh! ZEXAL series. It is regarded as a parallel world without Chaos and the counterpart of Barian World. According to Astral, only individuals who have "Ranked Up" in a spiritual way can reach this world. Originally it strives to "Rank-Up" towards a higher plane of existence by destroying Barian World, with which Astral was to achieve as its envoy. However, this has changed following the Duel between its godhead, Eliphas, and Yuma Tsukumo.
