The Devil Is a Part-Timer by Akio Hiiragi

The Demon Lord suffered defeat when attacking Ente Isla and retreated through a dimension portal.  Unfortunately, the portal sapped the last of his magical powers and he is now trapped in modern Japan with his loyal general.

Now they must masquerade as regular Japanese while trying to find a way to restore their powers.  This means that the Demon Lord is now Sadao Maou who works part-time at the local fast food restaurant.  But this is just the first step in his plan to take over Japan in this world before going back to rule over Ente Isla.


This is a hilarious manga series for teens.  Not only is Maou's plan nonsensical but he must also deal with the hero that has followed him to Japan and earthquakes caused by someone hunting them both.  This is a great series for those who like fantasy, humor, or adventure.
