I just read 7 chapters of this and I've gotten a few chuckles out of it. It has a lot of stupid awesome moments in it. (Like a guy taking out a room of thugs with his pimped out wheel chair)
Synopsis: Japan is now the 51st state of the U.S.A.. The isle of Neon, located near Japan, is the only place where prostitution and gambling are legal. There, Italian Mafia, Chinese Triad and Yakuza fight each other to gain the control of casinos and brothels.
Side Note: It is drawn my the same artist of Battle Royale, and in kind it is not safe for work.
Also it can be gory at times, so view at your own risk.

All I have to say is… wait until chapter 5... oh man.
Hope you guys enjoy it.
