Some nice fight scenes and very good animation aren't enough to salvage a bland cast and a story that is all over the place.
It's so rushed it feels like it started at episode 63.
This should be my kind of anime, but I just can't get into it.
I think mostly the problem is adapting an almost 100 chapters in a 13 episode anime, if you like some cool animation and fights scenes this is for you.
I wanna recommend the manwa but if you read the manwa it's very slow paced, if you watch the anime it's very fast paced, so it's kinda complicated, I guess it depends your preference.
