1. one piece. My absolute favorite anime. it's always number one to me
tokyo ghoul is so crazy and messed up and so damn awesome I love it
guilty crown, it's one of the saddest animes ever to me but has probably the best sound track in my opinion.
and just a few other favorite, or honorable mentions lol DEATH NOTE, BLUE EXORCIST, MIRAI NIKKI, SWORD ART ONLINE, and SKET DAN. please let me know which ones you like or suggest I like pretty much every type of anime. long or short, manga as well.
