The Devil is a Part-timer

This was a refreshing Isekai to watch; rather than going to a fantasy world, fantasy characters came to modern-day Japan. It was really funny and the characters had a great dynamic with one another. There was a fair amount of “fan service” but, it never degraded the anime. The biggest downside of the anime was that it was only 13 episodes and never got a second season. However, after 8 years, there is a rumored second season in production.
