Barely watched any new anime this year, so I will be doing my list for manga instead of anime.
Manga of the Year: One Piece! Totally should not be a surprise. It has been amping things up all year and we are now on the eve of a freaking epic war.Even going into the new year it is still going on all cylinders. All hail the king of manga, Oda! He is truly Odaweomse!
Runner-Up: Magi. Absolutely great manga(anime is less good). It has had a great year as well with one of the most epic finishes for a battle ever. I think the series is great and will continue to be great. So glad this is getting an official release(not t just wait for an official release of the Adventures of Sinbad).
(Honorable mentions, World Trigger for being the best new manga of the year, which is setting itself up to quite possibly being a long running series, and The World God Only Knows for having a great arc, even if it is below the top two)
Biggest Surprise: Bleach! I still hate Bleach. It is a waste of space and it has become a convoluted mess that I don't care about at all. So why is it my biggest surprise? Because of Mask de Masuline. He is an amazing character. I love him, and I didn't think I could ever care about anything going on in Bleach ever again. I know that he will die in one or two weeks since he is going to be fodder to show how Renji has improved.....but I don't care. Go Mask de Masculine, hear the cheers of your fans and WWWIIIIIINNNNN!!!!
Biggest Disappointment: Huh this is going to be hard. One hand there was Jasco which wasn't that good, but I wasn't expecting much from at any point. Then there is Naruto which has just completely fallen and is just uninteresting, but I think that it might have been that way at the beginning of the year and I really don't want to double check on where Naruto was at the beginning of the year by rereading any chapters. So I guess I'll go with Seraph of the End because I had no idea of what to expect going in, and I ended up with a crappy battle series that has a tsundere main character that I hate. The sooner this thing gets cancelled the better.
