Episode 06 of The Devil is a Part-Timer debuted a new ending filled with disturbing imagery that I believe reveals the true nature of the show. Throughout the ending, there are several motifs that stand out. The second motif is the clock theme. No matter the situation, she is always alone - often accented by empty theaters or wide, open spaces. The ending showcases Chiho going on several adventures - safaris, dancing, even into outer space.

Maou and Chiho are friends and colleagues. Chiho has confessed that she has feelings for him, despite knowing that he is a Demon Lord, as she started liking him before knowing of that fact, but Maou has not made any response. She grew angry when Maou offered to erase her memories of the incident with Lucifer. When they first met, she quarreled with Emi who was bad-mouthing Maou, thinking she was Maou's ex-girlfriend, but when the truth was revealed to her, they became close friends. Chiho serves as Emilia's morality pet.
Not much is known about Satan's Mother and Father. Only they died when Satan was just a young boy. He tells Emi that his first and last memory of his parents is watching them breathe their last breath.
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. Chiho is an average teenage girl of short stature who sports a highly curvaceous figure, with large breasts, a fact which is noted by several people and envied by other girls. She has big amber eyes and light auburn hair that reaches down to her shoulders, cut short with two locks branching out from each side,with each held in place with dark blue ribbons tied into simple bows.
