Zeno's Palace

Zeno's Palace (全王ぜんおうさまの宮殿きゅうでん, Zen-ō-sama no Kyūden, lit. "Palace of the King of All") exact location is unknown but it resides above a huge jellyfish that is located in between golden clouds and what appears to be outer space. It is also a separate location from the universes and very far away from them, with even the Angels, as stated by Whis, taking two whole days at full speed to do a one-way trip and four entire days for a single roundtrip, and being more reachable through teleportation, such as the Kai Kai used by the Supreme Kais.
