The store manager owns the drinking house that Jahy works at in the human world.

She is a nice person, who cares for and likes Jahy. She tends to call Jahy, Hii-chan, even though Jahy tells her otherwise. When she found out that Jahy can transform, she found Jahy to be even more cute. She isn't afraid of Jahy and that she comes from the Demon World and instead sympathizes with her about the hardships Jahy went through. She is also ready to scold her to take better care of the things she treasures.
