It does have some action (a few fighting scenes) but I don't think it fits on my action adventure fantasy manga list so I'm only going to add it to this list. It has no romance and focuses on the characters (mind you, it's intended for Shoujo) so it probably won't be too deep and I think it's important to note that the depths in the characters are lacking... Because it's for Shoujo (pretty eye candies).

Majin Devil is the connection of two stories. It begins with a young gang member who is transformed into a monster by the Majin Devil. The second is the story of how one boy genius uses his intellect to defeat the Majin Devil with the help of some allies he meets along the way.
