my favorites(because I can't pick one): black butler, pandora hearts, Yu-gi-oh (the original, not the remakes which were nowhere near as good in my opinion), death note and Inuyasha
@hopeless_imagination, @roseofnoonvale, Yeah, it is. It's pretty hard for me to choose from one (since I've seen a lot so far/can't remember them that easily/and also because I don't want to type a lot. I just want to finish my statement and not make it so long). So, I just went with the one I enjoyed a lot and seen (kind of) first.
