I like the fact that this manga isn't violent at all because most people think mangas are violent (and show naked women sometimes like Love Hina or Ranma 1/2) and won't read them because of that.

DNAngel is the story of a teenager who becomes Dark, a legendary thief whenever he feels love because of a curse that affect boys in his family when they turn 13. He must steal things at night until he finds true love (someone who will love both him and Dark). There's a joke about "true love" in the manga made by his grandfather who tells him he must find the "sacred virgin" and Daisuke thinks he's just talking about an art piece.
There's some sexual jokes in the manga actually but they are cute and funny, I'd say "PG-13 rated", kids wouldn't be upset by that. The plot may seem usual and remind most people of magical girl story but I like the way the author write it. Each character has their personnality and there's no real villain (
