Manabu Hamada

The eighth shogun, Tokugawa Yoshimune, fights against evil rampant in Edo while blending in with the common people as Tokuda Shinnosuke, the third son of a poor samurai retainer, commonly known as "Shin-san". The story depicts Yoshimune, who is shaken by the issue of succession, the drama within Edo Castle, and a difficult case involving a conspiracy that occurs in the castle town, with the addition of new characters and a sense of the era.

With the release of Uesugi Yoshitake approaching, the Toyokai receives an assassination threat against him. The leadership raises security, while Munakata Seizo restructures his group—naming Sakai Atsushi as underboss and Murata Kunio as his aide. Meanwhile, Sawamura Ryuichi and Soma Kunihito try to settle a dispute involving old comrades, but…

The Toyokai leadership fends off attackers, but the assailants’ identity and motives remain unclear. Suspecting the rival Teito Union, Uesugi grows wary. Assigned to Uesugi’s crew, Soma digs into their networks—uncovering traces of former Teito members like Sudo Reiji, who has fled overseas.

Seizo Munakata, taken in by Shigemasa Mukai, the boss of the Toyo-kai, runs a ramen shop while secretly handling the syndicate’s underground dealings. Former biker gang leader Ryuichi Sawamura and ex-finance bureaucrat Kunihito Soma decide to follow Munakata’s lead. But trouble strikes when Mukai’s wife, Harue, and granddaughter, Shizuka, are abducted by unknown assailants.

Munakata Seizo, who runs a ramen shop while secretly carrying out underworld work for Toyokai boss Mukai Shigemasa, gains a reputation for his efficiency—soon whispered about as the assassin group “Resshikai.” One day, Mukai’s wife Harue and granddaughter Shizuka are abducted.

Harue shields Shizuka but is gunned down by ex-Shindo-gumi member Yokoyama. Her death pushes Munakata to form his own group, and Mukai entrusts him with his dream of “conquering Japan from Yokohama.” Meanwhile, rumors of Munakata’s new organization reach the Hachio-kai. In Kyoto, Sawamura and allies move to settle a scandal tied to their associate Horita, but are ambushed by Gudokai, leaving Murata injured again. Elsewhere, Yamaoka visits Yokohama, seeking Toyokai’s help to eliminate Onda.

With Munakata Seizo as boss, Sawamura Ryuichi and Soma Kunihito establish the Munakata-gumi under the banner of Resshikai. Soon after, Shindo-gumi’s Shimaki, carrying the missing ransom money, shows up at Munakata’s ramen shop. Meanwhile in Kyushu, Shindo-gumi schemes with the infamous Moji family for profit.

When Toyokai underboss Eda collapses, boss Mukai appoints Naoe Takehiko as acting underboss. At Mukai’s request, Sawamura joins him for business talks in Nagoya. Meanwhile, within Hachio-kai, tensions flare as newly freed boss Shirota’s faction clashes with acting leader Kurose Akito over the group’s new direction.

After saving homeless Nozomi from an attack in the park, truck driver Ryuuhei offers Nozomi a part-time job in his truck and decides to set on an aimless trip. As they travel together, they encounter various eccentric individuals, including a deriheru girl (prostitute), a street poet, and a man who is being chased by the yakuza, and gradually learn about each other's circumstances.

Oda Nobunaga and Nōhime were originally married to mend a hostile relationship between neighbouring regions. Unfortunately, they were like oil and water, making for a somewhat unhappy marriage. When Oda's enemy, Imagawa Yoshimoto, attacks Owari with his vast army, Oda is devastated by the overwhelming gap in military strength. However, Nohime encourages him not to despair, and the pair draw up a tactical plan that will allow them to overcome the odds.
