The OverCelestial Realm is a dimension inside Futurax's Omniverse that contains 4 unknown realm that is very private and safe :

• Futurax's 'Unknown' OverCelestial Multiversal Palace
• OverCelestial Omniversal Fighting Dimension
• The OverCelestial Artefacts
• The Absolute Forbidden Dimension

... Futurax teleports you to the 'OverCelestial Entrence', where you can see 4 beautiful aura orbs that are portals.. you can only enter 2 of them.. the 3rd and 4th are FORBIDDEN, only Futurax, Naturax, Hydroza and Omniversal Miku can enter it...

Futurax : Here you are, don't forget that it's EXTREMELY serious here, it's the safest area of 'omni-existence'... I'll let you here. If you have any questions, scream out my name..

The "Autonomous Trust" is activated here, so if you have bad intentions, you're kicked out of this place and you go in 'non-existence'
