Kurohyō: Ryū ga Gotoku Shinshō

Plot

Tatsuya is an aimless youth on the streets of Kamurocho who is framed for an assault which left a young boy comatose. He drops out of high school during his second year and lives a hoodlum's life with Tenma (his only friend) and Saeko, his sister who raised him for nine years after their mother's death. Hearing about a large sum of money held by a loan shark, Tatsuya and several other hoodlums break in at night. Tatsuya defeats Naoki, not knowing he killed him.

After Toda's death, Tatsuya receives an untimatum from a member of his gang: win ten consecutive fights or be arrested. Tatsuya agrees, and as he fights underground he bonds with trainer Kudoh Saki and physician Amamiya Taizan.

He is shocked to find that Toda still alive. Through Kage the florist, Tatsuya learns that Toda had a body double, was responsible for the Champion District arson and was presumed murdered when police found his body outside the city. He also learns the truth behind the fight that landed him in juvenile hall for two years was from another acquaintance of Tatsuya who delivered the crippling blow after defeating his father.

Amamiya Taizan (Nogi Tooru) is Tatsuya's biological father and Saeko's foster father. When Saeko's parents were killed in the Champion District arson, Tooru and his wife adopted Saeko. When his wife died in another fire, he disappeared. Fifteen years earlier Naoki, needing money, helped commit insurance fraud by setting the Champion Street fire. He was paid by Tsutsui Masatoshi, a bullying land developer. Tatsuya defeats eight other fighters, beats Hyuga Shou twice and also defeats his father. He wants to learn what happened so Tsutsui will be arrested for the murders. Although Tatsuya defeats Shinjoh, his father sacrifices himself by taking a blow intended for him. Despite the arrests of Tsutsui and Shindoh, they were unable to find information about the true mastermind behind the conspiracy as the data about the extent of the consipracy was lost and all leads to the case are dead. In post-game credits, the final conspiracy member is disclosed: Tsurumi Tadashi, secretly working with Naoki to take over Kamurocho.

In the drama Naoki Toda is shot to death by Haruto, a member of Tatsuya's gang whose mother was killed in a gang war. In retaliation he kills Tatsuya's sister, tries several times to kill Tatsuya and frames him for Toda's death. In Tatsuya's final fight he is shot several times before Saki shuts off the power, allowing Tatsuya to defeat Haruto. Haruto, realizing he is about to be arrested, commits suicide with the final bullet in the gun.

Two years after the Toda conspiracy, Tatsuya boxes for the Tetsu Gym and returns to Kamurocho. He is met by the Ashura, an Osaka gang which attacks Shinji Tetsuji and Yuta Mikami. After a brawl with former fighter Tomoki, Tatsuya considers leaving until the Ashura try to take over the Dragon Heat and cripples Shinji who was their only worthy fighter. He again fights in the Dragon Heat, defeating Shinobu Okita.

The Ashura is heavily invested in Kamurocho and Soutenboori. Meteo Suzuki sells modified air guns as dangerous as pistols and Oba Shunsuke is behind OS Production, a show-business agency which is a Ponzi scheme. Nioka hires an assassin to kill Yuuta's father and a loan shark, but Tatsuya foils his plot.

When the Ashura kidnaps Saeko, Makoto delivers the ransom and sacrifices himself for her when the building in which she is held blows up by taking bullets meant for her. Tsurumi mobilizes his law-enforcement team to seize the city. Winning the final fight in Osaka against Akita, he says that Nogizaki Ryou, Makoto's childhood acquaintance, has the real power before a sniper silences him and the Ashura frames Tatsuya for the murder. He returns to the closed Dragon Heat and Ryusho, who is furious at Nioka for using the police to seize power. Tatsuya persuades Ryusho to save the ring, disclosing that Nioka had been betrayed by Tsurume and confronting him. Ryou arrives with Tsurume's brother to expose Tsurume's involvement in the death of his lover, Shizuka. Tatsuya defeats Ryou to keep him from killing Tsurume. Ryou takes bullets meant for Tatsuya, and he and Tsurume commits suicide through a self-inflicted gunshot wound and jumping off the Millennium Tower after being exposed. Tatsuya, putting the Ashura conflict behind him, continues his journey.
