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 μνΌλ΄μΈλ΄ style action scenes, as well as almost slice-of-life comedy. I would definitely try this one!
If λΉμ 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.
