Albedo

Albedo is a major character in the anime Overlord. She is a powerful succubus and serves as the Overseer of the Floor Guardians in the Great Tomb of Nazarick, making her the highest-ranking NPC under Ainz Ooal Gown (Momonga).

She was created by the Supreme Being Tabula Smaragdina. Albedo is renowned for her stunning beauty, described as having lustrous jet-black hair, golden irises with vertically split pupils, horns, black angel-like wings, and the face of a goddess. She typically wears an elegant white dress (or heavy black armor in combat).

Her personality is defined by absolute, obsessive loyalty and romantic love toward Ainz — a trait Momonga accidentally (and jokingly) added to her settings right before the game became reality. She's highly competent, level-headed in management duties, ruthless toward enemies (especially humans, whom she despises), and fiercely protective/jealous regarding Ainz.
