Chiho Sasaki

Chiho is Maou's friend and a fellow employee at MgRonald's. She has a crush on Maou. She can hear and understand the language of Ente Isla, after receiving feedback from a hypnosis spell that Maou cast on her father, Inspector Sasaki.

She has a strong will and a polite, friendly, pleasant all around personality. She is head over heels for Maou, and sometimes gets jealous when she sees Emi and Maou together.

She is a part-time employee at MgRonald's along with Maou. Maou had met her father when he first landed on Earth, as her father is a policeman and caught him and Ashiya loitering around. Chiho attends school at Sasahata North High School.
