After the young Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi) force a local yakuza family to disband, they leave Yokohama and head to Kobe where they meet members of the Kyowa Clan.

Himuro (Yasukaze Motomiya), who joined Kyowakai, steadily rose through the ranks with his calm and clear mind. Tamura (Yoshiyuki Yamaguchi) was also released from prison and Ryuseikai was thought to gain even more power. At that time, there is an internal split in Kyowakai as a whole, caused by an unusual executive appointment, and Himuro and others get caught in the vortex. After the conflict, the leader of the Ueda group, Ueda (Okazaki Jiro) and other gang members withdrew from Kyowakai, create a new organization called Shintokai in Kyoto, and attack Kyowakai executives.

With the Kyowa and Shinto Clans in open conflict, Tamura (Yoshiyuki Yamaguchi) looks for a chance to kill the head of the Shinto Clan as others attempt to forge a truce.

While the Kyowa Clan aims to unify Japan's yakuza after winning the war with the Shinto Clan, both Tamura and Himuro see unexpected faces in prison.

As Himuro is released from prison, word spreads that he has been asked to switch from Mikami's to Kawatani's Family.

Himuro (Yasukaze Motomiya) takes responsibility for Omiya's death. Tamura (Yoshiyuki Yamaguchi) succeeds the Omiya Family and targets Osaka, setting up a showdown between the former friends.

As both Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi) set their sights on Osaka, the Kyowa Clan takes advantage of an attack on an officer to declare war and invade the city.

The Osaka War ended in a complete victory for Kyowakai and he finally conquered Osaka. The leader of the Yamazaki group, Kawatani (Hitoshi Ozawa), who was accompanied by Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi), was recognized for his achievements and appointed head of the Kyowakai family. With the Yamazaki-gumi steadily gaining strength, Himuro set about reforming the Yamazaki-gumi organization and established a regular business to make it even bigger. Meanwhile, a skirmish between the young men of Tamura and the Yanagase Federation breaks out again in a conflict that spreads throughout Gifu following the Osaka War.

Himuro (Yasukaze Motomiya), who was appointed as the second Yamazaki-gumi wakagashira, expanded his influence in Gifu and Shiga, and even became known in political and business circles. However, he will bear a grudge against the Hiroshima mobster Genseikai. In the midst of this, Himuro and Tamura (Yoshiyuki Yamaguchi) are ordered by Kudo (Hakuryu), the leader of the Kyowakai, to intervene in the succession issue of the Shigemitsu family, the largest organization in Nagoya.

Under the command of the second generation leader of the Kawatani group, Himuro (Yasukaze Motomiya), the largest organization in Nagoya, the problem of the Shigemitsu family's heir is resolved, but the Hiroshima yakuza Genbukai and other groups of 12 organizations, the western Japan. be established. Shikoku, who became the vanguard, was invaded by Akashi, Hyogo, who is a Shinogi, by the Patriotic Giyuto, and Omoto, the head of Kyowa Kaisha, was killed. Burning with revenge, Himuro and Tamura (Yoshiyuki Yamaguchi) launch a violent counterattack.

A power vacuum left after the death of the Gijin Clan boss triggers new fighting in Shikoku, and Himuro (Yasukaze Motomiya) heads there to stoke the flames.

Kyowakai in the West and Marukami Rengo in the East are two major organizations vying to create a new order in Japanese yakuza society. However, in Tohoku, a conflict broke out between organizations that were conspiring to invade Tohoku by taking advantage of the problem of the heir to the Shobukawa family, a long-established Shinno group in Aomori.

Himuro (Yasukaze Motomiya) travels north to join the Tohoku fray, and a brief pause in the fighting comes to an end when a gunman attacks a Kyowa-linked loan company.

While the war in the Tohoku region intensifies after an attempt to assassinate the Shinyu Clan's Hirakawa, Himuro (Yasukaze Motomiya) pursues the man pulling the strings.

A skirmish in Fukui sparks a conflict between the local yakuza group Sakashita and the Kyowakai.

While the Kyowa Clan chairman recovers from a gunshot wound, Himuro (Yasukaze Motomiya) is targeted as well. A captured hitman admits that Sakashita ordered the attack.

After confirming that Fukumoto of the West Japan Mutsumi Association was behind the attempt on Kudo's life, Kawatani (Hitoshi Ozawa) declares all-out war.

Akimoto's incarceration and the retirement of the Marugami Alliance chairman re-ignite tensions in Kanto, while Fukumoto makes a new move in the west.

As Tamura (Yoshiyuki Yamaguchi) and his assassination squad deal with a corrupt detective, the Kyowa Clan deals with increasing disaffection within their ranks.

Tension continues at the Kyowakai headquarters. Kawatani, Himuro, and Tamura are unable to hide their anger and confusion at the events that occur one after another, such as Shibuya's death and a series of absentees from meetings. Meanwhile, in Kobe, a new anti-chivalry group is starting to move. However, Baba, who plays the role of chairman and does not know about Shibuya's death, postpones the official raising of the company.

The conflict in Nagoya has settled down, and Joji and Ryoichi are promoted to direct advisors due to their achievements. In addition, a parent-child ceremony with Kawatani will be held. Also, Himuro and Tamura were thinking about how to avenge the killed Shibuya. Meanwhile, the Kyoujinkai, fearing retaliation, seeks help from Hokuriku and attempts to draw in the Kitakoshi-gumi.

Himuro and Tamura of the Kyowakai finally take revenge by taking down the perpetrator of Shibuya's murder. While he was pouring out his thoughts in front of a grave in Shibuya, Baba, who was supposed to have defected to the Kyojinkai, appeared. On the other hand, the Marukami-kai in the Kanto region will no longer be under pressure from politicians, and a conflict with the Kyowa-kai in the Hokuriku region will become inevitable.

Himuro and Tamura put an end to the suffering of Munakata, the leader of the Fujishiro-gumi of the Marukami-kai, and expanded the Kyowa-kai to the Kanto region, but soon after, they receive news of Munakata's suicide. When Himuro saw the suicide note, he became suspicious and concluded that it was the work of Tsurumi of the Marukami-kai, who was the first to discover it. The conflict between Himuro and Tsurumi becomes even more intense.

Tatsumi of the Marukami-kai is isolated from the Marukami-kai and is chased away by the Kyowa-kai and the Marukami-kai. Himuro invites Tatsumi and his friends to Nagoya and attempts to settle the matter, but ends in failure. Tatsumi escapes and gets the civilians involved, and as the situation worsens, Himuro tries to set a trap for Tatsumi and his friends.

The Marukami-kai and the Shichinin-kai have joined forces with the Kyowa-kai, which is planning to expand into Tokyo. The Toyukai is heavily influenced by the Sasashima Foundation, which controls the center of Japan. After Hasegawa is killed by Toura of the Hassei-kai, Himuro and Tamura notice that the money that the local bank had previously lent to the Hassei-kai has gone uncharted.

The Kyowakai, including Renji Himuro and Yuto Tamura, have advanced to Tokyo. Himuro and Tamura, who are trying to delve into Japanese taboos, hear a certain fact about the Sasashima Foundation from Horii of the Dainippon Sokai. On their way back, the two are attacked by Keihin Rengokai members, but are rescued by an unexpected person.

Tsushima, the chairman of the Toyu-kai, is unable to stop Kazami from going out of control, and Kazami finally privatizes the Seven-nin-kai on his own. Himuro and Tamura are attacked by Kazami at the hotel and have a tough time. Due to Kazami's strategy, Mita, the president of the Marukami-kai, is arrested, and Kazami orders him to return the Marukami-kai's shima to the Toyu-kai, but...

Himuro, the Wakagashira of the Kyowakai, and Tamura, the head of the club, crushed the Gozen in Kamakura and the Ginza/Toyukai, and abolished the rental Jima system in Tokyo. Himuro, who exchanged sake with the Yaguruma-kai's successor, holds a funeral for the Yaguruma-kai's predecessor in Tokyo in order to show the re-formed Kanto Seven-nin-kai that the Yaguruma-kai is alive and well and the prestige of the Kyowa-kai.

Marukami-kai Nakamori-gumi leader Nakamori and Himuro are shot by someone, and Himuro is taken to the police for questioning. Meanwhile, Tora and Teru are making a fuss at a club in Kazo and are about to cause some trouble. It was Himuro and Tamura's strategy to destroy the Kanto Seven-person Society, but...

The 55th installment of the popular chivalry series starring Yasukaze Motomiya and Yoshiyuki Yamaguchi. This is a success story of two people, Renji Himuro and Yuto Tamura, who aim to reach the top of the Japanese Yakuza world with the goal of "eliminating conflict from Japan." Characters with rich individuality are dynamic and adhere to the path of chivalry that "helps the weak and frustrates the strong." Tora, a member of the Yamazaki clan, was arrested by acting as a decoy to protect Tamura. What is his parent Tamura thinking? Set in Yokohama, the movements of the Kyowa-kai, the Shichinin-kai, and the police intersect in a flashy manner.

One day, a special investigation team suddenly begins a raid on the Kyowakai. Tamura (Yoshiyuki Yamaguchi) concludes that it is Iwao (Daisuke Negishi) of the Sakoda group, but Himuro (Yasufu Motomiya) denies this. According to Kawatani (Hitoshi Ozawa), who was investigating, he was forced to join the Kyowa-kai due to a tip from Inspector Matsumiya (Gen Hongo) of the special investigation team. Himuro and his friends become suspicious and try to find out the source of Matsumiya's information, but...

With Hamada's death, it seemed that the Yuseikai's problems would be resolved, but an incident occurred in Yokohama in which a member of the Nakamori group was attacked. Matsumiya (Gen Hongo) once again assumes that this is the work of the Kyowakai and investigates. Meanwhile, the captured Kawakami (Tatsuya Nakazawa) and Ryuji (Tatsuya Kishida) are attacked by someone when they are released.

Makimoto (Tomohiro Waki), Arimura (Tasuku Nagaoka), and Itagaki (Keisaku Kimura) of Koukai, who shot Iwao (Daisuke Negishi), escape. Himuro (Yasufu Motomiya) prioritizes taking the seriously injured Iwao to the hospital. Himuro and Tamura (Yoshiyuki Yamaguchi) stubbornly refuse a thank you from Sakoda (Hideo Nakano) who rushes to the hospital. Afraid of conflict in the near future, they avoid colluding even though they have a common enemy, the Steel Association.

One day, while Himuro (Yasufu Motomiya), Tamura (Yoshiyuki Yamaguchi), and the Yamazaki clan are watching the news, they hear shocking news. Gang members had barricaded themselves in the area and fired at the police officers who arrived. When Himuro learns that the scene is Tokorozawa, he wonders if it is Shima from the Sugimasa group. According to Sahara (Takayuki Kaneba) of the special investigation team, the incident was triggered by a tip-off that Gota, a member of the Sugimasa-gumi, was the head of Shabu, but Miyazono, the head of the Sugimasa-gumi, would have done something like that. Himuro couldn't accept that there was no such thing.

Himuro (Yasukaze Motomiya) starts a fight to crush Shimizu (Yasuaki Maeda) and Takahashi (Masashi Goda) of the Sugimasa group. They discover that Takahashi is involved in the smuggling of shabu and weapons in Tokorozawa, but Takahashi commits suicide before he can say anything. The Marukami-kai intervened after learning that the Sugimasa-gumi conflict was due to the Kyowa-kai. The time has come for a direct confrontation between the two major organizations of East and West.

Himuro (Yasukaze Motomiya), Tamura (Yoshiyuki Yamaguchi) and others discover Ruby's true identity and discover a large amount of firearms and shabu. He tells Sahara (Takayuki Kanema), a member of the special investigation team, that the series of incidents was not the work of the Kyowa-kai and the Marukami-kai, and advises him to investigate the relationship behind the incident. Himuro suspects that there is a mastermind among the police, but Sawara is similarly suspicious of Matsumiya (Gen Hongo) and others. Meanwhile, the police begin to arrest Mita (Shun Suda).

Nao (Nishikawa Ayano) is the wife of Ota (Ryota Matsushima), a legal advisor to the Seagull Victims Association, who has been captured by the religious organization World Seagull Church. Tamura (Yoshiyuki Yamaguchi) enters the cult's facility alone to rescue his girlfriend Nao. Himuro (Yasukaze Motomiya) notices that Tamura has boarded the vehicle and heads to the facility alone as well. At the direction of the founder, Takahara (Nishikawa Mizui), the two of them fight against the believers who come armed with weapons, but they are unable to stand against the overwhelming numbers and are captured.

Himuro (Yasukaze Motomiya), Tamura (Yoshiyuki Yamaguchi), and others drive the Seagull Church to ruin. After settling the matter, Himuro decides to return to Kobe with Joji (Takashi Kitashiro). Together with Tamura, who had been left behind, Himuro began to feel that Kobe was like his home. These thoughts brought back memories of Himuro and Tamura's past, when they were quick-tempered thugs running wild in Yokohama.

Joji (Takashi Kitadai) is shot by Isamu (Hidemi Higa) and collapses. Ishizawa (Hiroto Honda) and Yamamura (Kenta Kawasaki) rush towards him and he flinches when they draw their guns, but Joji stops them. Concerned about the fate of Yuu and his friends, Joji decides to instead flee to Kawatani (Hitoshi Ozawa) and Himuro (Yasukaze Motomiya) in order to help them escape from the Masaki group.

The incident occurred without any warning. A member of the Kyowakai was shot in Kyoto. This shooting incident, which took place in Kansai—the very region Kyowakai was supposed to have unified—sent shockwaves through Himuro (Yasukaze Motomiya) and his men. As Himuro and Tamura (Yoshiyuki Yamaguchi) hurriedly prepared for an emergency executive meeting in Kobe, they were stopped by Kuroiwa (Susumu Terajima ) from the Hachiwari Police Department, who came to visit the Himuro-gumi. According to Kuroiwa, Matsumiya (Hongo Gen) from the special investigation unit believed that this incident was an internal conflict within the Kyowakai. Himuro and Tamura learned that the reason for this suspicion was a clash between Hayashida (Shu Ehara) and Kamiyama (Naoki Yamazaki) over a land redevelopment project in Kyoto. Determined to get to the bottom of the matter, they set out for Kyoto. In that area, various people’s emotions and interests were intricately intertwined…

The land redevelopment near Kyoto Station drew Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi) to the scene. Amidst the chaos, Kenjiro (Kenta Satoi), the local residents' association head and Reiko’s (Reira Arai) father, was shot dead. A distraught Reiko accused the Kyowakai, leading to Himuro and Tamura being separately questioned by the police. Meanwhile, Minami (Rin Asuka), who was like a sister to Reiko, struggled with mixed emotions. In Kanto, Okada (Yuki Matsumura), the newly released Okada Union president, saw this as a chance to crush the Kyowakai, sending shockwaves through the Marugami-kai. However, Mita intervened. Within the Kyowakai, Kawatani also ordered restraint against the Marugami-kai, but tensions continued to rise…

Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi) returned to Tokyo to confront Okada (Yuki Matsumura). However, waiting for them was a notice of succession from the Hasekai, which was supposed to be under the Kyowakai's control. Upon learning that Okada’s faction had ties to the Hasekai's new successor, Himuro immediately severed ties, bringing the direct showdown between the Kyowakai and Marugami-kai closer. Meanwhile, Reiko (Reira Arai), who had been hiding with Genji (Kuroishi Takahiro), continued living in hiding, harboring distrust towards Genji and others. Despite this, she remained focused on her vengeance against the Kyowakai. While Himuro and the others tried to clear up Reiko's misunderstanding for Minami (Rin Asuka), Reiko refused to listen. Gradually, she became more involved with Okada’s faction, who were willing to use anything for the war against the Kyowakai.

A sudden notice of succession from the Hasekai arrived from the Marugami-kai. Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi) were furious and stormed into the ceremony. Mita (Shun Sugata) saw this as a declaration of war and vowed decisive action. The police, led by Matsumiya (Gento Hongo), ramped up surveillance on the rising tension between the Kyowakai and Marugami-kai, leading to the arrest of Teru (Yutaka Kyan) and Saito (Katsuya), escalating the crisis. Amid rising tension in the Kyowakai, Nakajima (Yoshimi Tachi) sought revenge for Shoji’s death. Concerned about Minami (Rin Asuka) due to Reiko’s (Reira Arai) involvement, Himuro and the others were encouraged by Kawata (Hitoshi Ozawa) to proceed. Himuro’s plan set up a clash between Kuramoto Kogyo and the Keihin Rengo-kai. Though it initially went smoothly, Jun (Goro Washida) and Chosaku (Keishi Kawaguchi) interfered, creating new complications.

The death of Minami infuriates not only Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi), but the entire Kyowakai organization. As Kyowakai prepares for an all-out retaliation, Chairman Kawatani (Hitoshi Ozawa) orders all executives to stand down and forbids any act of revenge. Meanwhile, in Marugami-kai, Chairman Mita (Shun Sugata), feeling responsible for dragging a civilian like Minami into the conflict, decides to expel Genji (Kuroishi Takahiro) and his men from the group as atonement. Even Senior Advisor Sakota (Hideo Nakano) can’t hide his fury at Genji’s despicable actions. However, Chairman Okada (Yuki Matsumura) of the Okada Union opposes Mita’s decision. While Mita fully understands the risk of triggering a deadly clash with Kyowakai, Okada and others, dissatisfied with Marugami-kai’s stance, launch a surprise attack on the Fujishiro-gumi, a group operating within Kyowakai's territory—igniting an explosive confrontation.

Himuro (Yasukaze Motomiya) launches an all-out assault on the Okada Union, led by Okada (Yuki Matsumura) of the Marugami-kai. While the police suspect Kyowakai’s involvement in the string of attacks, the group feigns innocence. Acting on Kuroiwa’s (Susumu Terajima) tip, Special Investigator Matsumiya (Gen Hongo) summons Okada, but the tense exchange nearly turns explosive. Outside the station, Himuro and Tamura (Yoshiyuki Yamaguchi) lie in wait—until they spot Kawatani (Hitoshi Ozawa) watching too. Just before they act, they stop him. Kawatani walks away, leaving them with: “Take care of the Kyowakai.” As tensions escalate between the Kyowakai and Marugami-kai, Ryuji (Tatsuya Kishida) remains unconscious. Burdened with guilt, Nakajima (Yoshimi Tachi) secretly prepares for revenge. At last, Kawatani and Mita (Shun Sugata) face off for a final showdown.

A month has passed since both the Kyowakai and Marugami-kai lost their leaders, yet silence reigns between the two syndicates. With Chairman Mita (Shun Sugata) gone, the Marugami-kai remains leaderless, while the Kyowakai reels not only from the loss of Kawatani (Hitoshi Ozawa), but also from Himuro (Yasukaze Motomiya) and Tamura (Yoshiyuki Yamaguchi), both lying in critical condition. Even the police keep watch nervously, and Kuroiwa (Susumu Terajima) is left uneasy, with no word on Himuro’s survival. Inside the Kyowakai, unease grows as the executive ranks clash over their next move. Meanwhile, Marugami’s Shinjo (Masanobu Sakata) and Komiya (Ryoichi Inaba) see their chance—determined to crush the Kyowakai, now weakened with Nakajima (Yoshimi Tachi), Ryuji (Tatsuya Kishida), and their top three all absent. Amidst this turmoil, Tamura finally regains consciousness. But with both syndicates on shaky ground—can a miracle save Himuro and Kawatani?

Kawatani (Hitoshi Ozawa) leaves Kyowakai, naming Himuro (Yasukaze Motomiya) as the 4th Chairman. But with Himuro hospitalized and Tamura (Yoshiyuki Yamaguchi) stuck in Kobe, the leadership seat remains empty. Unease spreads among the executives, and tensions rise between Baba and Hirakawa. The Special Investigation Unit intensifies its crackdown on Kyowakai and Marugami-kai, arresting Kawakami for the hospital attack. Learning the police still can’t reach Shinjo and Komiya, Nakajima heads to the Fujishiro-gumi, but struggles with his failing physical condition. Meanwhile, a new scheme emerges, and drugs once again flood Yokohama. Amid growing chaos, Nakajima makes a critical decision—
