The Celestial Crowbar is a tool that is used throughout the One Winged Angel series. It is one of the most powerful tools that Maion has. It is capable of teleportation through the realms, and can fix a lot of things that usually can't be fixed. Later, it is shown to blast pure energy at foes. It seems to be partially omniscient, as whoever defeats the wielder is supposed to have full control over it, but Maion was still able to use it fully even though she did not defeat Irene or the Demoo Overlord. The wielder usually has full control over the object, to the point where foes cannot even pick it up unless they defeat the wielder.
It also seems to have a limited memory of it's wielders, and can be used to teleport to past wielders.
