Midarezaki Kyouka
The 'mother' of Midarezaki family. She is twenty years old, however, she has an appearance of a little girl with cat's ear and tail. Her real name is 'Kyoukya Eaeriaea', and she used to be worshiped by the people of an underground kingdom named 'Shangri-la', however, she ran away because she felt something was missing from her life. Due to her past of being worshipped, she has a very arrogant and destructive nature, but despite her personality, she actually cares about her family and is trying to do her best as Ouka's wife, getting very jealous when she found out Ouka went out with another woman. She is also a very bad cook, where her meals frighten everyone in the family.
Midarezaki Ouka
The 'father' of Midarezaki family who is forced to participate in Cozy Family Operation. Sensible and collected, however, he is often teased and mocked by Kyōka. He lost his parents at the age of three, and has no memory before then. He is also the head of the operations department of 'Supernatural Phenomenon Treatment Bureau'. He has clearly stated to Kyouka that he is unable to love someone, yet he does treasure the family and likes her (which made her blush).
