Togainu no Chi ~Lost Blood~

In the years following a third world war, a devastated Japan is divided between two rival factions with no hope for reconstruction in sight. Caught between East and West, Tokyo has degenerated into a brutal, crime-ridden wasteland. Like many of those reaching adulthood in this dark new world, a young man named Akira seeks some kind of meaning in the violent street fighting contest Bl@ster. But even as he rises up the rankings, he feels almost nothing. Is this all there is? In Toshima, a district of Tokyo ruled by the mysterious syndicate Vischio, the blood sport Igra makes Bl@ster look like child's play. Competitors have the chance to win control of a drug empire worth more than in their wildest dreams, but losing a bout means losing your life. When Akira is arrested for a crime he didn't commit, a strange woman appears with an even stranger offer: he can regain his freedom if he fights his way to the top of Igra and destroys Vischio from within. What dangers and revelations await Akira on Toshima's pitiless streets? Is he strong enough to survive them?
