Celty Sturluson

Celty is a slim, tall woman who can be easily mistaken for a man. She has pale white skin, and her head is shown to have brown hair and blue eyes. In her early years, it is shown that Celty wore knight's armor as she traveled the country side with her head resting on her lap. When she immigrated to Japan, she updates her attitude to match the times. For most of the series, Celty is shown to wear an all black biker jumpsuit with black gloves and shoes. With the exception of pajamas and slippers shown in the anime, all of her clothing is made from a shadow-like substance that materializes around her at her will. She also wears a yellow and blue helmet that vaguely resembles the shape of a cat's head.

Personality Celty's personality is, ironically, one of the most normal and down-to-earth compared to most of the other characters. Although she was fairly emotionless in her early life, she has since developed a much more defined personality as she has spent more time with humans. She is generally a confident and optimistic individual, although she is not without her insecurities. Chief among these are her concerns about how people will react to her monstrous nature. In the start of the series, Celty tends to avoid most people as they usually react negatively upon realizing she has no head. However, she has recently begun opening up more to people as she encounters others who are not only accepting of the paranormal (such as with Shizuo Heiwajima or Anri Sonohara) but seem to reveal in it (such as Mikado Ryuugamine or Izaya Orihara).

Based on the Monster Musume anime. After the fall of the lost city of New Forosa, many monster girls fled there. Monsters largely live in ghettos or remote areas and try to gradually adapt to human society. But the process is slow, and they suffer a lot of discrimination. Demihumans are commonly referred to as monster girls as 97% of them are girls and only 3% are born male, some being born human men. The ADIE is the organization that monitors monster girls
