Chisa

The owner of the restaurant Jahy works at. Her sister is the landlady of the apartment Jahy lives in.

She is a nice person who cares for Jahy. She tends to call Jahy "Hy-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 instead sympathizes with her situation.
