The Devil Is a Part-Timer!

はたらく魔王さま！

In another dimension, the Devil King Sadao is only one step away from conquering the world when he is beaten by Hero Emilia and forced to drift to the other world: modern-day Tokyo. As "conquering the world" are the only skills the Devil King possesses - and are obviously unnecessary in his new situation - he must work as a freeter to pay for his living expenses.
