The Devil is a Part-Timer [TV]

The Demon Lord and one of his generals, Alciel, escape Ente Isla through a portal to modern Tokyo, Japan after being confronted by the Hero Emilia Justina and her companions. However, due to the lack of magic in the modern contemporary world, both the Demon Lord and Alciel change into forms representing what they would look like if they were human. In order to survive, the Demon Lord takes a part-time job in a fast food restaurant named MgRonald while Alciel serves as his houseman. One day, the Demon Lord, who now goes by Sadao Ma?, meets a girl who is actually the Hero Emilia, who now goes by Emi Yusa. The story then unfolds and explores the personalities of each of the characters and their moral values. More characters show up from Ente Isla and they too face the new world dilemmas, often comically.
