Heartwrenching tragedy of a boy who starts off with everything and then loses it all. Ryuuji Kazama was born into yakuza. He loses his parents to a battle between groups Kazama and Kuroda. He then loses his aunt who raised him and his nephew (who watches him kill the people who killed him mom). He gets raped repeatedly in prison until Ryuuji finally is released from prison. He is taken in by Hitoshi Araki, who use to look after Ryuuji when he was younger. The two finally are together but are separated early by death due to Hitoshi being stabbed. The war is finally over when Ryuuji kills Iba (whose held a grudge against Hitoshi for soooo long) and has his identity purged through witness protection that Hitoshi had set up previously. We meet Kai and Araki Masanori from Kizuna manga :)
