15. Good Ol' Tenchi, Saber Marionette J & Ranma 1/2. :3 They're some of my FAVORITES. I feel the same way, I LOVE them as long as they have a different plot. Try Ai Yori Aoshi if you haven't already. :3 It's one of my favorites and it's a really unknown series but it's really good for a harem series.
