The Devil Is a Part-Timer!(はたらく魔王さま！)

Foiled by a hero when he’s inches away from conquering the world, the devil finds himself in modern-day Tokyo. With no real-world skills to speak of, the devil is forced to make ends meet flipping burgers at a fast food joint! To stall any further plans of world domination, the hero tracks the devil’s trail and takes on the lowly tasks of a telemarketer.
