Which do you prefer? the manga is a fresh story line however the extra detail and emotion the anime series adds makes it all the better. We're ignoring the fact that anime has filler since it progress faster than manga.
Both in my opinion, even if into the anime there are some gaps, some things are not exacly as good as in the manga.. but nothing so important; it's great anyway
I chosed ANIME because, it's in color for one & the action in it flows where as in the manga it's black & white & can't really see much action going on in it.
anime for sure, manga is great but it's black&white and details are hard to see, anime is in color, and there are movements, sound so you can realy enjoy it AND a episode is longer then the manga 16-17 min anime contra 3-4 min manga each week
the manga is great for the story line its to the point and quick no fillers where as the anime is best in the big action scenes seeing them move around in color is best to me
