The flag banner is located on the 10th Floor of the Great Tomb of Nazarick. Particularly, it can be found hanging on a flagpole attached to the ceiling within the Throne Room. However, in the New World, this flag was later destroyed by Momonga with a [Greater Break Item] spell after declaring to Nazarick's NPCs that from this moment forward, he will be called "Ainz Ooal Gown" over his player name.
On the other hand, the flag is still lingering around somewhere in Nazarick as Albedo was shown to have one in her possession. It was originally stored in Albedo's Item Box inventory but was put out for display whenever she is alone by herself inside Momonga's bedroom.
The flag banner seems to be gigantic in size to the point that it resembled an opera curtain. Visually, it is imprinted with a sigil under the intricate shape or outline of a face.
While there is no clear indication of its abilities being known, this flag serves as a representation of Momonga through the symbol embellished into it. Such sigil-like symbol embroidered on the flag is distinctive to only himself.
- Apart from Momonga, the other guild members of Ainz Ooal Gown were also said to have a respective flag of their own type.
- Albedo affectionately preferred the Flag of Momonga over the Flag of Ainz Ooal Gown which she happens to have a dislike for.
