This manga is clearly one of those examples where an awesome art could make everything seems better, and I'll tell you why.
If you think about the story, the premise is quite interesting. An apocalyptic world where all the people have to survive from evil living beings who try to devour them. Their origin is unknown and one day an strange girl stronger than them appears. What's happening?
I've always been a great fan of suspense stories and this inmediately caught my attention. Nevertheless, there was a problem: this manga wasn't addictive. This could sound as something very "personal", and yeah, it is, but I
can imagine anyone finishing a volume and desesperating feeling like starting the next.
However, as I said in the beginning, the art of this manga is fucking fantastic. There was a point when I was more focused enjoying every single detail in the character desing and the battle scenes than in the proper story.
Anyway, if anyone asks me if I'd recommend or not this manga, I'd say it has an entertainning story and one of the best arts I've ever seen.
