はたらく魔王さま！

Satan, the Demon Lord of Ente Isla, flees through a portal to modern-day Tokyo after the hero Emilia Justina routs his armies. Stripped of his magic, he takes the name Sadao Maou, rents a tiny apartment with his general Alciel, and starts working the register at MgRonald's. Emilia follows him to Tokyo, still intent on finishing the job, only to discover that her sworn enemy is now her neighbor scraping by on minimum wage.
