Frey

"Sky Queen" Frey is a former member of Demon Lords and currently is a subordinate of Demon Lord Milim Nava.

Appearance
As a harpy, Frey has wings on her back and talons as feet. She has white hair and is usually seen wearing a red dress.

Personality
Frey is careful and cunning.

Background
Frey is the queen of harpies, and belong to the same demon lord generation as Carrion. She was initially not involved in Clayman's plan of making a new puppet Demon Lord but later on choose to join in order to boost her own influence as well.

Relationships
Milim Nava: Frey cannot work against Milim. Though they were both Demon Lords, there is a clear difference in power. Also being a Dragonoid Milim's flight cannot be canceled out using magic jamming. Truly her natural enemy. Hence, she became Milim's follower. After her expulsion, she officially became Milim's direct subordinate.

Despite being Milim's subordinate, Frey acts more as a mentor to Milim, instructing her on how to rule over her newfound land. Milim, however, often escapes Frey's lessons to join her bestie, Rimuru, causing Frey to frequently scold her.

Clayman: Frey considered Clayman to be a cunning and tricky opponent to handle.

Carrion: Her fellow former Demon Lord, workmate under the same master.

Charybdis: Frey's natural enemy who possessed the same intrinsic skill as the harpies: Magic Interference. This skill negates the tactical advantage of the harpies' flight, making Charybdis their natural enemy.
