Soul Eater is good if you haven't seen it. So is Fullmetal Alchemist, Spice and Wolf, Hetalia Axis Powers, xxxHolic, Tsubasa, Chobits, Saiyuki, Blood+, Mushi-shi, Gunslinger Girl, Kaze no Stigma, Trigun, School Rumble, Lucky Star, and Burst Angel.
I hope this helped! =D I hope you can find something that you like from this list! ^_^ You can also try a few anime sites and see what titles they have and see if anything pops out at you. Happy hunting!
