Kanjuro, a character from the popular manga and anime series “One Piece”, played a crucial role in the Wano Country Arc. He was a member of the Kozuki Family and a retainer to the Shogun of Wano Country, Kurozumi Orochi. Kanjuro was also a member of the Beast Pirates, who teamed up with Orochi to gain control over Wano Country.

In the arc, there were many battles and twists, and Kanjuro’s story arc was one of the most critical parts. It was later revealed that Kanjuro was a traitor to the Kozuki Family and had been working with Orochi and the Beast Pirates all along. He had been providing information to Orochi and the Beast Pirates, which ultimately led to the downfall of the Kozuki Family and the capture of the Straw Hat Pirates.
In Chapter 984 of the manga, it is revealed that Kanjuro was responsible for capturing Momonosuke, the son of the former Shogun of Wano Country, and handing him over to Orochi. Kanjuro had been pretending to be a loyal retainer, but he revealed his true allegiance and captured Momonosuke.
In the final battle between the Straw Hat Pirates and the Beast Pirates, Kin’emon, one of the leaders of the Kozuki Family, fights against Kanjuro. Kin’emon is infuriated by Kanjuro’s betrayal and fights him. In Chapter 986, Kin’emon defeats Kanjuro, and it is suggested that he dies in the battle.
Kanjuro’s death has a significant impact on the other characters, especially the members of the Kozuki Family. Although his death is not shown explicitly, it is heavily implied in the manga that he dies in battle against Kin’emon.
In conclusion, Kanjuro’s death is a crucial event in the Wano Country Arc of the One Piece series. His betrayal of the Kozuki Family and his alliance with Orochi and the Beast Pirates led to his demise in the final battle against Kin’emon.
