I have all ways been a fan of MMOs/RPGs, so when I saw this anime preview I really couldn't wait to see it.
I'm not entirely sure what the reason could've been, but this anime was somewhat addictive. Yes it did have some slow points, but don't most of the anime have some. One thing that I really enjoy about this anime was the story and the fighting. The fighting was the one that kept me on edge, waiting to see what was going to happen next. It felt like the story could've end at any time.
I recommend this to anyone who likes action and MMOs/RPGs games.
