Pandemonica

Pandemonica was originally full of all of Vanripper's favorite traits, like being socially awkward but polite, archaic in an elegant way, and a tired hard worker; However, upon remembering that Helltaker was supposed to be a game about bad demon girls, Vanripper added a more sadistic side to her personality which is brought out after she drinks coffee. In this state, she expresses frequent violent urges, including a willingness to break the Helltaker's fingers should he not brew her a good cup of coffee. In "Yet Another Short Comic About Demon Lore 🐑", it is revealed that Pandemonica's sadistic behavior in her caffeinated state may possibly be avoided by brewing truly good coffee.

Pandemonica, like most of the Helltaker cast, is depicted as a short demon girl with pale skin, red irises, a black arrow-tipped tail, and silvery-white hair. Her hair is wavy and fashioned in 3 large curls resting on her forehead, with the middle curl being larger than the two on either side. It reaches down both sides of her head, tucked behind her ears, with both ends curling inwards at the bottom of her head close to her chin. Additionally, she has a pony tail on the back of her head with two more large, distinctive curls. Poking out of her hair are two small black horns that are rounded at the tips. She has white eyebrows and has visible dark circles under her rounded eyes, giving her a tired appearance as her alias would suggest; after drinking coffee though, her eyes become much more sharp and angular, and her horns grow much larger, first curving in toward her ponytail and then upwards, and are much sharper. Over her eyes are a pair of round-framed glasses

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.
