Welcome to Demon School, Iruma-kun

The show takes a blend of some of the most common tropes in shounen. The setting is simply the typical highschool anime only this time, set in the underworld. Even better, welcome to demon school doesn't rely on cliché tropes like tsundere, harems and fanservice. Peculiar about this anime is the main character who is human but is able to somehow blend in with the underworld.

Don't take the show seriously. The anime is mostly comedic and it pokes fun at several shounen tropes. Personally, I enjoyed the show because of how smartly and ridiculously it tries to hide the true human identity of the main character. As a result, the anime got innovative; introducing new adventures each episode.
