Niku Kuroinu

ニク・クロイヌ, Meat Blackdog

A dog-eared beastkin. Her first name Niku means Meat, a slang term for a sex slave. Her last name was later given, meaning "Black Dog" Her origins are unclear, but she was purchased as a slave by some bandits, to be used as the bandit leader's dakimakura. She was saved by Keima, and became his slave and dakimakura. She looks up to Keima as her Master, and is very happy to be of use to him, looking up to him despite being stronger than him in physical power.

She likes hamburgers, as well as being Keima's dakimakura. She is also Rokuko's dakimakura on occasion.
