A Chinese Nijiura Maid, based on the Hundun (混沌) - one of the Si-xiong (Four Fiends) mentioned in Chinese mythology. As such, she is often seen with fellow Si-xiong maids Toukotsu, Toutetsu and Kyuuki.
Konton appears as a small furry girl with long green hair that covers her eyes. She has an ahoge and sidelocks that hang down in a manner similar to dog ears (like Inu-T's hairstyle.) Her body is dog-like and covered with grey/light brown fur, but this is usually hidden under her outfit with the exception of her paws, tail, and occasional face fur.
Her maid uniform is a white apron over what appears to be a long-sleeved black changpao with yellow trim.
In mythology, Hundun represents chaos. It is known as a "faceless beast" and portrayed in some interpretations as a dog, which explains why Konton is a dog girl and her eyes are always hidden.
