Great Mage Demia

Great Mage Demia is the name of a human mage, and the Archmage revered for her magical prowess. She first appeared in Chapter 21 of the manga and Episode 10 in the anime adaptation.

Personality
She's a snide mage with a lot of power. Due to the fact that she runs a succu-joint solely on clones of herself, it's likely that she is pretty full of herself. Besides that, she's sweet yet careful for the people around her that she works with.

History
Demia previously wrote a report on the Will-o'-Wisp's censoring light ("The Optics of Respectability"), as said in Episode 06.

She helped concoct The Genderswap Inn's Genderswap Potions as said in Episode 09.

She owns a perfect-scoring brothel in Magic Metropolis, also established in Episode 09. There, you pay to do anything to a complex decoy doll of her for 3 days straight. The first line drawn was outdoors though, due to that being a public nuisance. The audience is formally introduced to the real Demia at the end of Episode 10, stationed below.

Demia is very interested in Crim's halo, and wants a piece.

Abilities
She is the best Archmage on Earth, knowing everything about magic. She can create Demia Dolls, Decoy Dolls with more advanced actions.

She is also a skilled cook, which can also be transferred to her Demia Dolls.
