Fourth Shinobi World War: Confrontation

The Shinobi World War Arc spans at chapter 515 to current. It covers the Fourth Great Shinobi World War where the Five Great Shinobi Countries all ally into the Allied Shinobi Forces to oppose Madara Uchiha and Akatsuki, all to protect the last remaining jinchūriki, Naruto Uzumaki and Killer Bee. The War arc formally began in chapter 515 with the war finally starting with both the Allied Shinobi Forces and Akatsuki moving out for battle.

Battle of the Ambush Squads
The first battle to happen in the war was when the two Ambush Squadrons met in battle. Kankurō lead the Surprise Attack Division against Sasori, Deidara, Chūkichi and Shin of the Surprise Attack and Diversion Platoon, having been resurrected by Kabuto Yakushi to fight in the War. Shin tried resisting the control, yet attacked against his will against his own brother Sai and his comrades. Through clever maneuvering and strategy, as well as Deidara enraging Sai, both Deidara and Sasori were captured in Kankuro's Black Secret Technique: Machine Triple Shot. After seeing the picture finished in Sai's picture book, Shin's ties to the world were severed and he could pass on, breaking the Summoning: Impure World Resurrection. Chūkichi was returning to reinforce Deidara and Sasori.
