Read through 135 chapters so to sum it up this is a work of art. The monsters are truly horrifying! Very dark manga with good plot, and great art. As you read they reveal more and more of the back story. It is confusing at first but it will click. I really like the character designs. There are many twist in the series as well that may blow your mind. If you do not mind intense gore and can get through sexual explicitness, and love complex plots as well as dark stories try it out!

P.S There is excellent horror (fear and suspense) and a touch of classy romance which is an interesting mix

To go from the mediocrity of I''s to this, so much respect for this mangaka.
Keep in mind as you read this manga that there will be two protagonists. There's one arc where it follows and establishes the second protagonist, showing only him for multiple volumes. This can feel kind of annoying/long/less interesting. But by the end of that arc it was as good as the rest of the series. So when you reach that point, just keep reading.

And the whole series is building up the the confrontation shown in the flashforward in the prologue. Really excellent job done here.

Zetman's romance feels a little off, but the other protagonist's was done really really well.

And Haitani is one of my favourite villains of all time.
So good.

It has a unique plot in my opinion, plus decent character development (although the main character is pretty static). And I love the whole dark and twisted theme behind the entire story, its definitely a piece of work made for seinen fans (dont read if u hate seinen)and its very different from Katsura Masakuza other works. Overall a very interesting read.

hmm keep reading this manga, unlike what the other guys said, 10 or 20 chapters later the main character returns. Though you would think this is a superhero manga looking at the (lame btw) name, its more seinen like, definitely not recommended for children. Ah, as others said, the romance is quite nice too, i definite recommend you to read this.

As many have mentioned the story is quite start-from the ending-go-in-future-go-back-present etc... But still, after reading vol 7 im positively suprised and looks like this manga will be in my top 10 all time favs if it keeps up this =) You shouldnt give up on this just because of the side story, it will most likely blend nicely. Art is also top quality and character design is very cool ;]

Read it!

I never thought the mangaka of I''s (which is my favorite romance manga) could make such a good shounen. It's definitely between my favorites, but it would be better if someone scanlated the chapters faster...

i am a person that won give high rating b4 i see it's ending. But certainly this series have a promosing storyline n great art. So far so good but we will never know wat will happen if it has a great or a crapist ending so just wait and see. Plz dun make quick assume.

You are in for a treat if you like 20 volumes of setups ending with "to be continued in Arc 2".

Also, like other KATSURA Masakazu's works, none of the characters is likable.

Brilliant series, couldn't put it down and ended up losing a little sleep because of that.....anyway dark ambiance, decent action scenes, slightly confusing in some parts with just that bit of romance make this an awesome read. I do have 2 annoyances though mostly personal (a) It makes a good read but the feels they hurt. (B) ACT 2 WERE AND WHEN

at first, like the first 40ch or so i am completely lost. why this, why that, what the hell just happen? but as the story progress and i get to see farther and farther into the landscape i appreciate the intricately made storyline. this manga have weird flow, it jump and stop where i thought it shouldn't but if you bear with it you can get what it mean in the end. i like the different character design, so somehow i can differentiate between characters which is quite rare these days. sometimes the posing is a bit too much, the expressions a bit too crazy, but this is seinen after all. i'm not into jin's struggle so i think kouga really help in making me feel a bit attached to this manga - he is so stupid and naive, but in the end his heart is in the right place.
this is worth a read.
