Chiho Sasaki (佐々木 千穂 Sasaki Chiho?) is Maou's friend and fellow employee at MgRonalds. 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 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. She attends high school at Sasahata North High School.
Chiho expressed her concern about the recent earthquakes she had been experiencing to Maou. When they started occurring on a larger scale, she sent a text message to Maou, asking if they could meet up and talk about it, to which Maou agreed.
Chiho dolled up, hoping to impress Maou, and is delighted when he didn't mind calling their meet-up a date. When they discussed the issue at a restaurant in an underground mall, Chiho also mentioned a strange voice she had been hearing that said a 'big one' is coming. When Chiho was about to confess, Emi showed up with Ashiya, and warned Chiho not to get too close to Maou. This made Chiho assume that Emi was Maou's ex-girlfriend, to the latter's chagrin. The underground mall collapsed then. Chiho woke up amidst rubble in the company of Emi, who reassured her of her relationship with Maou. Emi put her to sleep after that. After they got out of the rubble safely, the police recognised her as Inspector Sasaki's daughter and thus she bid farewell to Maou and Emi, going to her father.
The next day, when Chiho paid a visit to Castle Overlord, she found Maou and Emi together and concluded that they do have some history. Torn, she ran off and was taken hostage by Lucifer, who used her inner turmoil to his advantage. Later, she witnessed the battle against Lucifer, and thus found out about Maou and co.'s true identities. Albert revealed to her that he was the voice she had heard; his Sonar had been aimed at those who thought of Maou constantly.
She has a strong will and a very try-hard personality. She is in love with Maou, and sometimes gets jealous when she sees Emi and Maou together.
Her school uniform has a dark green scheme; it has buttons running down the front with a plaid ribbon at her chest and a light green collar. Her skirt is the same color as her collar, and the look is completed with black knee-high socks and brown shoes. Chiho's chest size is often envied by other girls. She is of short stature but sports a highly curvaceous figure, a fact which is noted by several people.
At MgRonald's, she wears the standard employee's uniform and wears her hair up in two ponytails.
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 quarrelled 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. She is sometimes envious of the situation between Emi and Maou as Alas=Ramus's parents.
Powers and AbilitiesEdit
Although Chiho is a normal human, she has some powers and abilities of her own due to her frequent interactions with Maou and others from Ente Isla:
Thanks to the Sonar used on her, Chiho is now able to understand the language of Ente Isla like a native speaker would. It is unknown if she can speak it herself, however.
She is capable of using a bow, as she is part of the archery club at school and is shown practising with one in the opening credits of the anime. In Volume 5 of the light novel, she had the chance to display her skills in archery, when a mysterious being lent her some powers to take on angels who came to cause harm to Maou and Emi.
- According to the Data Books, she is a 1st dan kyūdōka as attributed to her belonging to her school's archery club.
