Togainu No Chi. The Blood of the Guilty Dog. Volume 4

After the Third World War, Japan, divided into Eastern and Western parts, was left in ruins.
On the ruins of the former capital - Tomisha, a brutal and merciless "game" is taking place. The winner is promised untold treasures and absolute... power.
In addition to opponents who are willing to do anything for such stakes, there are many dangers: enforcers from the drug enforcer "Whiskio" who kill anyone they deem a violator, and the lone wolf Shiki, whose motives are unclear and whose katana shows no mercy... the main character, Akira, sets off to the city with the mission to defeat the king of the "game," the legendary Il Re.
Will the strength of an experienced street fighter be enough in a world of underground battles where it's not just a fight for life or death?'
