Ruberu (Cerberus Monster Girl)

She looks like a thin, twenty-year-old woman with a canine appearance. Her skin is covered in blue fur, she has furry ears, and a snake for a tail.

The heads of her hands look like plush dog puppets, but they're part of her, using their mouths to grab things. They have their own personalities.

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.

Cerberus is a pseudohuman species of being that features prominently in Greek mythology.

Said to be the guardians of the Greek underworld known as Hades, the Cerberus are noted for having three heads, each with their own conscious personalities, and a snake as their tail. In Greek literature, the hero Heracles was tasked with retrieving a Cerberus from Hades as the final of his 12 labors.

Trivia
Ruberu's two heads are called Ke and Su. All three together would be Ke, Ruberu, Su (Keruberos, the Japanese way of saying Cerberus).
