They arrived in the Azum Dimensional Realm sometime later, with the entrance being nothing more than a quite simple Spatial Gate. It was open in the very center of Azum City, which took the Dimensional Realm's name. The city was considered one of the biggest ones in the Angel Realm, even though it wasn't exactly close to the center of the Heavens.
Obviously, the city reached that size due to the Azum Dimensional Realm, as it was purposely built around the Realm's entrance. When Ran's group got close, they noticed that the Spatial Gate was indeed simple, but at least it was quite big. It allowed for many angels to enter and leave as they saw fit and was very stable.
And as always, any Golden Tickets and Stones are welcome. ;)
