Albedo

The heroine of the series. She oversees the Floor Guardians and is recognized as the holder of a World-Class Item, Ginnungagap, standing at the pinnacle of all NPCs in the Great Tomb of Nazarick. She claims to be Ainz's consort.

Despite her peculiar appearance, which includes black angel wings from her waist, goat-like horns growing from her temples, and golden eyes with vertically slit irises, she is usually an exceptional beauty. Her wings are also used to express emotions. In battle, she goes fully armored in the jet-black "Hermes Trismegistus" and wields the bardiche "3F" with a sickly green glow. She possesses high-level abilities due to being Lv100, and her classes are focused on defense, making her a protective shield for Ainz with top-tier defensive capabilities.

She excels at managing Nazarick’s internal affairs, and her competency in this area is unmatched. Originally, she had a long, detailed background set by a guild member who was a stickler for settings, which included the phrase "incidentally, she is a bitch." Near the end of service, Momonga whimsically changed this to "she loves Momonga,” leading her to deeply love him after the game's service ended and the world changed.

In her role, she often stands by the throne beside Ainz, reprimanding Guardians for their failures and advising on actions that could weaken the authority of Ainz Ooal Gown. However, her loyalty and affection are exclusively directed towards Momonga, not necessarily extending to the guild he loves. She harbors resentment and dissatisfaction towards the other guild creators, viewing them as having abandoned the NPCs of Nazarick. Moreover, she has a strong dislike for humans.

In the popularity poll conducted on Nico Nico Seiga from June 20, 2016, she ranked second.
