devil within 
the true devil is the devil within
Hey guys! During my silent moments on theO, I came across many fascinating Animes I would like to recommend. And as a start, I would like to recommend Hataraku maou-sama.
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 Maō, 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.
There is great humor, action, and bits of romance. A great anime/manga to watch when you want something to cheer you up.
