Mibuo Reika

A housekeeper who has worked at the mansion for several years.
Although generally calm, she is a little absent-minded and has a hint of a shotacon...?
She is in charge of managing the entire mansion and also becomes Ayane's conversation partner.
She sometimes enjoys telling strange rumors and ghost stories to scare everyone in the house.

"My favorite is only Master Tsukiya. Ah, Master Tsukiya, how adorable you are."
