This is a pretty realistic fighting manga , as realistic as works of fiction can get concerning the subject of fighting , and from what little information there is on it on the net , seems like that was it's downfall.
The story isn't original , a bullied kid who snaps and realises giving is better than receiving ( especially if it's pain ). It starts of well , the first few chapters are interesting , they make you want more. After 3,4 chapters i though "hey this is the new Holyland ! "... but... it was canceled. And as a consequence , quite a bit
of action and the ending were rushed , obviously it didn't become what it could've been , and as a whole it's a bit disappointing.
There isn't really much that can be said about the characters , they're fairly cliche.
The art is ok , the fights are brutal , well drawn , full of blood , and interesting.
In conclusion if you're looking for a realistic manga , that can be a bit depressing and very bloody give Gekiryuuchi a try...
