モモ・パルミラ・ファルスタッフ

Momo is a middle-class humanoid spirit who has a contract with Dan Saliel. She is not suitable for conflicts of any kind, including having no fighting skills. Her best ability is housework, as a result she is forced by her contractor to always wear a maid outfit and often gets bullied by him. Despite this, she still admires Saliel very much. Momo relieves her sadness from the bullying by tending to her pet goldfish, Tama. [Translated from Wikipedia in Japanese.]
