one of them is ONE PIECE because not only is it like my second favorite anime but the manga goes a lot faster than the anime and its cool to see the diffrences between the manga and anime.
Next is RAVE MASTER because i never got to finish the anime since CN pulled it off the air and it's not that bad of a story. it's sorta original if you ask me.
Lastly it's NARUTO. I read it in Shonen Jump and i like to see the diffrence between the manga and anime, plus cuz i use Naruto mangas to try to draw my original characters in the same kind of design. same with one piece and rave master.
