Story-9 Personally I started the manga after reading about its beginning in one of the covers of Fairy Tail and I immediately fell in love with the story, till this day I cannot say I have read something similar and although in some cases I think they handle the story in a quick way, then they end up convincing me of the opposite.
I never thought to read a story about firefighters, much less one like this ... possibly a little cliche the fact that all humanity is at a crossroads where that will decide if the planet will face it's end or not, but at the same time it gives a serious air to the series.
Art-8 Very good, easy to understand and with a perfect style for a Shonen Manga like this one, personally I think is good enough, other Mangas have become very popular having a worse style.
Characters- 8 You can find original characters, characters with really good background stories, with good sense of humor, intelligents, very bold and also the typical characters of a Shonen anime. They are trying to embrace with their characters each of the possibilities that can exist in a world as the story unfolds.
I will not talk about the enjoyment since I think it's pretty personal, but overall, this Manga is pretty good, will make you have really good time while you're reading it.
