Not very specific, just need a anime that will keep me interested, so some action but some romance mixed in, something supernatural or fantasy would be nice but it doesn't have to be. hmmm lets see what else, what else, oh yeah something like to love ru or Marburaho or DearS where the main heroine is a childhood friend or supernatural/sci fi creature who looks human who appears in the main protagonist life and what happens afterwards but yeah thats pretty much it WARNING: earliest it can be is 2004 and MUST it MUST be shonen (or for boys is the translation)
It's been a month since I posted this thread XD
UPDATED LIST:
