Plot

In 2022, three years after the Tojo Clan and Omi Alliance's joint dissolution, ex-yakuza Ichiban Kasuga is an employee at Hello Work, an employment agency in Isezaki Ijincho, Yokohama, determined to carry on his father Masumi Arakawa's legacy by helping ex-yakuza find legitimate work. By 2023, VTuber Hisoka Tatara spreads false rumors of Kasuga building his own crime ring, which causes Kasuga and his friends Yu Nanba and Koichi Adachi to become unemployed. A month later, they learn that the Seiryu Clan has been recruiting ex-yakuza en masse. They infiltrate the Seiryu Clan HQ and meet their Acting Chairman, Masataka Ebina, who reveals that he is hiring ex-yakuza into a legitimate waste management business and that he is organizing a "Second Great Dissolution" to disband the remaining yakuza clans across Japan. Ebina informs them that he is working with Jo Sawashiro, who has been released from prison after being proven innocent, with the former's help, in the murder of the previous Seiryu Clan Chairman Ryuhei Hoshino. Sawashiro reveals to Kasuga that his biological mother, Akane Kishida, is alive and has been living in Honolulu, Hawaii, and asks Kasuga to meet her.
Upon arriving in Hawaii, Kasuga befriends the wheelchair-using engineer Eiji Mitamura. Kasuga has run-ins with taxi driver Eric Tomizawa, who attempts to rob him, and later with Akane's maid and exchange student Chitose Fujinomiya, who strips him naked and steals his passport. Kasuga is arrested by police and escapes; he is then saved by Kazuma Kiryu, who is looking for Akane per the Daidoji faction's orders. While investigating Akane's house, Kasuga and Kiryu are confronted by the Yamai Syndicate and their patriarch, Yutaka Yamai, who is also searching for Akane. Tomizawa, who is coerced to work for Yamai, defects to Kasuga's side. Kasuga's group discovers that Chitose used Kasuga's passport to hide within District Five, home of the Barracudas gang. Kiryu reveals that he has cancer, contracted from an accident at a nuclear waste disposal plant in 2020, and he has only six months left to live.
The party infiltrates District Five and finds Chitose, who joins them to confront the Barracudas leader Dwight Méndez. Gaining intel from Chitose, the party discovers that Akane was part of a religious charity group called Palekana and that two of Hawaii's largest gangs, the Barracudas and the Chinese Ganzhe Mafia, are also after Akane. With assistance from Kiryu's handler Kihei Hanawa, Kasuga confronts Wong Tou, the Ganzhe's commander, and learns that the Barracudas and the Ganzhe are secretly controlled by Bryce Fairchild, the Sage of Palekana and "the Overseer" of Hawaii's underworld. Bryce is hunting down Akane to find Lani, a young girl currently under her protection. Wong is then betrayed by a spy, forcing Kasuga's group to escort Wong to safety, while Kiryu is captured by Yamai. Nanba and Adachi, having arrived in Hawaii, join Kasuga to confront Yamai, who was providing medical care to Kiryu out of respect. Learning of Bryce's true objective, Yamai calls off pursuing Akane. Kiryu returns to Japan with Nanba for recovery, while Kasuga confronts Bryce, who escapes.
Returning to Kasuga's apartment in Ijincho, Nanba is joined by Geomijul and Yokohama Liumang leader Seonhee, and hostess club owner Saeko Mukoda in helping Kiryu recover and manage his condition. Seonhee is later informed that the Seiryu Clan is planning to expand its waste management operations to Hawaii. Kiryu meets Ebina and Sawashiro at the former Tojo Clan Headquarters, where Ebina reveals he got the idea for his waste management business from Palekana, who runs a similar business on Nele Island and plans to partner with them. However, they claim they have no knowledge of Palekana hunting Akane. Later, Tatara publicly exposes Kiryu's survival and claims he plans to resurrect the Tojo Clan, seemingly corroborated by Ebina and Sawashiro.
Kasuga tracks Akane and Lani hiding in a yacht offshore. En route to a Daidoji safehouse, Akane reveals that Lani is the last surviving member of the Mililani family, the true successor to the title of Sage of Palekana, and that Bryce usurped the position by murdering the previous Sage. Upon reaching the safehouse, Chitose reveals that Eiji is a Seiryu Clan spy, who faked his disability to gain Kasuga's trust. The Barracudas raid the safehouse, killing Hanawa and Wong, while Eiji escapes with Lani. Chitose then confesses that she is Tatara, having been blackmailed by Eiji to spread online accusations against ex-yakuza across the country and serve as a spy on Kasuga's party. Kasuga focuses on rescuing Lani, while Kiryu focuses on Sawashiro.
Former Liumang leader Tianyou Zhao allies with Kiryu as they confront Sawashiro, who reveals that he has been secretly working behind Ebina's back to actually carry out the dissolution. Sawashiro realizes that Ebina's plan is a ruse after sending Kasuga to Hawaii, in order to expose Akane as a favor for Bryce. Ebina plans to make a deal with Bryce to store all of Japan's accumulated nuclear waste on Nele Island, allowing the government to resume Japan's nuclear industry. Sawashiro and Kiryu, however, share the belief that there's an ulterior motive behind Ebina's plans. Kasuga learns from surviving Daidoji agents that Eiji used to be a reporter who was framed by the Arakawa family for a hit-and-run and previously joined non-profit organization Bleach Japan to enact vengeance on the yakuza. Chitose makes amends with the party as they attempt to rescue Lani, but fail as Eiji flees with her.
Sawashiro sends Kiryu to Tojo Clan leaders Daigo Dojima, Taiga Saejima, and Goro Majima to expedite the dissolution. Kiryu meets them, where they reveal that a prior Tatara Channel exposé on their ex-yakuza employees shut down their security company. Daigo also reveals that Ebina may be Arakawa's illegitimate son and Kasuga's half-brother. Fearing another failure, Daigo, Saejima, and Majima refuse to help Sawashiro. Tatara, replaced with a substitute by Eiji, exposes the meeting, causing public backlash and a manhunt for Kiryu. That night, Tatara holds a live stream at the former Tojo HQ with Ebina and Sawashiro, where Ebina announces his deal with Palekana, the dissolution of the Seiryu Clan, the reformation of Bleach Japan, and his plan to pass their yakuza rehabilitation program to the government. Kiryu's team raids the former Tojo HQ, but find that the live stream was pre-recorded.
Joongi Han, Seonhee's right-hand man, arrives in Hawaii to help Kasuga infiltrate Nele Island. Kasuga's party investigates a secret passage within District Five, which leads to a hidden port heading to Nele Island. Lani is rescued from the Barracudas, and with Yamai's help, the party, Lani and Akane escape to Japan. Having failed Bryce, Dwight attempts to escape but is eaten by a shark. Upon arriving in Japan, the party is greeted by Kiryu's friend, Detective Makoto Date, who reveals that in exchange for a passage back to Japan, Yamai would confess to the murder of Shuji Tabata, Yamai's former patriarch. Yamai bids the clan's matriarch farewell and turns himself in.
With Lani and Akane safe in Japan, Kasuga and Kiryu regroup in Ijincho, where Ebina contacts them, saying that the rehabilitation program has been approved by the government, then reveals that he has Sawashiro hostage at the Millennium Tower in Kamurocho, Tokyo. The group then splits up: Kasuga's group returns to Hawaii to stop Bryce, while Kiryu's group assaults the Millennium Tower with Daigo, Saejima, and Majima's assistance. In Hawaii, Kasuga's team assaults Nele Island and discover a natural cave filled with barrels of nuclear waste, revealing Palekana's waste disposal facility as a lie. Kasuga confronts Bryce, who reveals his plan to use the island to store many nations' darkest secrets and gain global influence. Kasuga defeats him, and Chitose livestreams the entire facility's nuclear waste and confesses to being Tatara.
Kiryu's team confronts Ebina and find a barely living Sawashiro. Having a grudge against Arakawa and the entire yakuza, Ebina reveals his actual plan behind the Palekana deal: to force the yakuza to work on Nele Island's nuclear waste disposal, slowly torturing and killing them with radiation poisoning. Kiryu defeats Ebina, and as he sympathizes with his anger, begs him to give the yakuza a chance to atone. Kiryu then falls unconscious and is evacuated to a hospital. Meanwhile, Kasuga tracks down an injured Eiji hiding in Kamurocho, and convinces him to turn himself in.
A month later, the public has largely moved on from the Seiryu/Palekana controversy. Tomizawa devotes more time to helping the homeless in Hawaii, Chitose becomes the chairwoman of her family business, and Lani assumes her role as Sage to rebuild Palekana with Akane's assistance. Kasuga attempts to properly confess his feelings for Saeko, but inadvertently embarrasses her by wearing a t-shirt celebrating their relationship. Meanwhile, Kiryu's adopted daughter Haruka Sawamura and her son Haruto visit Kiryu at the hospital just as he's about to receive treatment. When the doctor asks to confirm his name, Kiryu answers with his real name.
