Tsubasa Resevoir Chronicle, Fruits Basket, xxxHolic, Death Note, Shaman King, Gravitation, RG Veda, Immortal Rain, Fushigi Yugi, Loveless, Black Cat and Ouran Host Club. Yep, I'm reading all those (I borrow Gravi and Ouran and buy the rest). I read Shaman King in Shonen Jump so I read everything else in there too, but Shaman King's my favourite.
