Summary: It follows the life of a homeless boy living with his "grandpa". The story starts to kick off when they encounter a man trying to commit suicide mumbling something along the lines of "before it is too late". Of course from then on the action begins and the dark plot begins to unfold with each volume.

[Art:] The art of this manga is simply amazing. The mangaka takes the time to put details in the background which expresses an atmosphere as you read, something that many others don't take the time to do. The art is also looks pretty realistic, the design of the characters are well-drawn and detailed too. You can also see the art get better and better as you read on which is quite fun.
[StoryLine:] It is an interesting combination of characteristics that really makes the story unique. The story follows a male [Zet] who is born with super-natural powers, but wants to become a human and a male [Kouga] who is born a human and wants super-natural powers. Zet was a successful scientific product of the study of "Players", a monster-like being where he got this powers from, while Kouga is a normal human who wishes to gain powers. The two males pretty much have opposite personailites.
Another pro of this is that the mangaka continues with the atmosphere throughout the entire series, where as others express on atmosphere and suddenly discard it and change it to another. It makes the story seem much more realistic.
By the way, the fighting is good-ol'-punching with a mix of super-natural beings. There aren't any dumb power-ups or overpowered enemies either!
Note: There are some mature scenes.
I rate it 9/10.
