Expu is a chaos god who resides in the 3D Realm, being one of the only living beings in the dimension aside from his brother and any entity who enters the realm. Most of the entities who once resided in the realm were killed or deformed after playing REDACTED's twisted games, which often results in Expu wandering the realm to fix and repair any broken space and/or entity that was destroyed in the progress. She is very lonely and would like to have a break from the frivolities surrounding her.
