In One Piece Chapter 975 the Straw Hat, Heart, and Kid Pirates arrive. These three crews have always had a natural affinity for each other. The Captains, Luffy, Law, and Kid have always had a passive-aggressive relationship. They’re always bickering while competing with each other for glory. Despite the surprise appearance, the Beast Pirates are still confident that they will win. Insulted that they’re being looked down upon, Luffy, Law, and Kid attack. Kid uses “Punk Rotten,” Luffy uses his “Boundman,” and Law uses his “Room.” They destroy one of the ships. Kyoshiro and his family arrive. Assuming that he’s on their side the Beast Pirates beg him to sink the enemy ships.

He cuts one of the Beast Pirates ships in half. Then he tells the Samurai that his family will aid them. He tells Kin’emon about the “Mountain God incident.” Kin’emon quickly deduces that Kyoshiro is Denjiro. Joined by 1000 Samurai he freed from Rasetsu Town Prison, Denjiro offers his 1200 soldiers. He reveals that Yasuie altered the message to the allies. However, he assumes that it was deliberately done by Kin’emon. Orochi was too late to stop the ships. All the troops are gathered at Port Habu. With all his ships, Denjiro tells everyone its time to go onto Onigashima. 

Kin’emon successful blunder

I don’t know the point of having Kin’emon blunder his way into success. I’m certain it will pay off in some way, but right now it’s odd. I always love seeing Luffy, Law, and Kid together. While we have seen the alliance between the Strawhat’s and Heart pirates before, Kid has become more interesting this arc. Due to his reputation for killing civilians, Kid was easy to read as “evil.” A foil for Luffy, Kid shares his dream of becoming Pirate King and finding the One Piece.

This arc showed that Kid has little trust for other pirates (as he was betrayed by Hawkins and Apoo) and hatred for Yonko. Like Luffy and Law, he’s willing to fight them. He also has a love for his crew, as seen when he was concerned for Killer. Despite an alliance of over 5000, they’re at a serious disadvantage. The Beast Pirates have 20,000 fighters, along with Big Mom and some of her kids. Along with Orochi and all his men they’re up against it. The question is where’s Jimbei? I think he might be the difference.
