Anime Profile: The Devil Is a Part-Timer!

In an alternate dimension, a powerful demon lord is one step closer to securing a world for himself when he is defeated by his greatest enemy. Spent, the demon lord, along with his faithful general, is forced to seek shelter at the first place he lands – modern-day Tokyo! With no powers to speak of, the demon, now in the form of a teenager named Mao Sadao, has to survive in order to make a return to battle. The only problem is he now has to do it – by working flipping burgers and dealing with difficult customers at a fast-food restaurant! And to make matters worse, the enemy that beat him, also powerless, is in Tokyo as well – and she's looking for him... mainly to finish him off!

In another dimension, a supernatural battle is waged between good and evil. The Demon King Sadao is just one step away from conquering the world, and the final battle between him and Emilia's forces rages on. However, there is one unfortunate and unexpected twist... they both wind up in Japan on Modern day Earth.

Finding out that Sadao and his servant have lost all of their powers and are forced to live as normal human beings, they literally find themselves as fishes out of water. So what is a Demon lord hellbent on conquest to do? Work in the fast food industry! Sadao also learns that Emilia herself has followed him to Earth and she also must learn to adapt to the customs of Modern Day society. For both of them, adapting to the customs of Earth might bring about a great change in both of them. Whether they like it or not....
