Pony Canyon will produce a television anime adaptation of Touno Mamare's Maoyū Maō Yūsha (Archenemy and Hero) fantasy novel series.

The story centers on the characters Maō (Demon Queen) and Yūsha (Hero) who live in a world where humans and demons are at war. Yūsha confronts Maō about the destructive war that the demons have imposed on humans. However, Maō tells him that the war has created a reason for humans to work together and improved human society overall. She convinces him that humans would fall into a bloody civil war without their battles against the demons. To prevent such a conflict, Yūsha decides to join forces with Maō.

The series began on the 2channel forum before Enterbrain began publishing the series in 2010. Its five volumes have sold over 450,000 copies, and there are also Episode 1: Nire no Kuni no Jo-Mahō Tsukai (The Sorceress of the Country of Elm) and Episode 0: Sakyū no Kuni no Yumi-zukai (The Archer of the Country of Dunes) spinoff novels. The series has already received several manga adaptations.
