Grayfia Lucifuge is the wife and Queen of Sirzechs Lucifer and the mother of Millicas Gremory. She is the older sister of Euclid Lucifuge and sister-in-law of Rias Gremory. Known as the "Strongest Queen" and "Silver-Haired Queen of Annihilation," Grayfia possesses immense power rivaling the Four Great Satans.

Despite her noble upbringing from the Lucifuge clan that served the original Lucifer, Grayfia now loyally serves the Gremory household as their head maid. She fell in love with Sirzechs during the Devil Civil War while fighting for the Old Satan Faction and later married him after the war ended.

Personality & Appearance

Grayfia maintains an elegant, refined demeanor, befitting her status as a high-ranking devil and former heiress of the Lucifuge clan. She is calm and strict and believes strongly in decorum and proper etiquette. She also shows her family a warm, caring side despite outwardly denying her relationship with Sirzechs.

As an older sister, she cares deeply for Rias and Euclid, though she sternly reprimands them when they misbehave. Grayfia can also become flustered by Sirzechs's antics and has a reportedly troublesome personality when intoxicated.

Appearance-wise, Grayfia is a beautiful silver-haired woman with a voluptuous figure who appears in her early 20s. As the Gremory maid, she wears a traditional blue and white French maid outfit. Off-duty, she has a more casual style, exposing her midriff.
