The Devil Is a Part-Timer!

A comic fantasy series by Satoshi Wagahara, illustrated by 029 (Oniku). Defeated by the hero Emilia and routed from Ente Isla, the Devil King Satan flees through a dimensional gate into modern-day Tokyo, where he is stripped of nearly all his power.

Adopting the human identity Sadao Maou, he takes a part-time job at a fast-food restaurant to survive — a plan for eventual conquest repeatedly derailed by rent, coworkers, and Emilia's own arrival in Japan to stop him.

Originally serialized in Japan as a 30-volume light novel run (21 main novels plus prequel, spin-off and bonus volumes) published 2011–2020; Yen Press publishes the English translation. A separate manga adaptation by Akio Hiiragi is catalogued under its own volume numbering.
