The Devil Is A Part-Timer! is highly recommended. It lacks a bit in the romance department, but the characters are super lovable and the story is really good, as well as hilarious. There's some supernatural style action scenes, as well as almost slice-of-life comedy. I would definitely try this one!
If you don't mind some ecchi humor (panty shots mostly) I would try Is This A Zombie? It's pretty funny, at least to me, and the characters are great.
