What would You suggest

I would like some recommendations for anime. I have been watching Naruto, Bleach, Fairy tail, Nurarihyon no mago.
I enjoy a good storyline and decent characthers. The story shouldnt be too dark and a little bit of humor is very much welcome. If you recommend an anime please dont let it be with guns or machines or any like that (new tecchonolgy) but likewise with good animation and not the "old style" anime. I like supernatural powers, sword fights, magic fights ; the characther getting stronger trough the series(not required)

I think I made a pretty long list of requirements so please if you can answer me soon so I will have some anime to watch during the holidays :)

Thanks a lot in advance :D
