Albedo

Albedo is the Guardian Overseer of the Great Tomb of Nazarick, responsible for supervising all seven Floor Guardians. She was created by Tabula Smaragdina alongside her sisters Nigredo and Rubedo; originally programmed to crave frequent romance, her settings were later rewritten by Momonga so that she became obsessively in love with him instead.

In public she is composed, elegant, and sharp — Nazarick's daily administration effectively runs through her, and even Ainz admits she reaches conclusions he wouldn't think of himself. That composure vanishes the moment her feelings for her master are involved: she grows jealous of anyone who gets close to him and can lose control entirely if he is threatened or insulted.

She holds open contempt for humans, viewing them as an inferior species, and regards Shalltear Bloodfallen as her rival for Ainz's affection — though by her own admission, only guardians like Demiurge can match her in raw intellect.
