This show just concluded its broadcast in the Spring Season. I just thought that I'd bring it up because it's a (personally) likable fantasy/comedy series based on a series of LNs.
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!
I'm particularly taken by its "villain's redemption/atonement" theme here. A once-powerful and evil Demon King who was forced to live as a human and is starting to learn about them and gradually see the errors of his ways: this isn't something that I'd actually come across everyday of my anime viewing life, to be honest.
