Chapter Summaries

Naruto Uzumaki grew dissatisfied with ordinary shuriken and learned from Senju Kenya that mass and velocity made a weapon more powerful. After Kenya demonstrated the destructive force of a gigantic iron shuriken, Naruto began training with them, shocking Kakashi Hatake and Sakura Haruno as they passed by.

• Naruto Uzumaki complained that ordinary shuriken were too weak to harm powerful opponents.
• Senju Kenya explained that a thrown weapon's killing power came from its kinetic energy and called for Haku to bring Naruto's training equipment.
• Haku brought a cart of enormous, forty-kilogram iron shuriken, and Kenya hurled one hard enough to shear apart a distant hill.
• Naruto started throwing the heavy shuriken under Kenya's threat to throw him like one if he failed to shatter five peaks in ten minutes.
• Kakashi Hatake and Sakura Haruno witnessed the shuriken smashing the mountainside, while Sasuke Uchiha watched from behind a tree.

Sasuke asked Senju Kenya for brutal special training and endured an hour of beatings, which awakened his Three-Tomoe Sharingan. Kenya rewarded him with a chicken drumstick and ordered him to finish his remaining push-ups.

• Kenya gave Sasuke a roasted chicken drumstick and told him to finish his remaining thousand push-ups.

After days of beatings and heavy meals, Sasuke awakened his Three-Tomoe Sharingan and gained tremendous physical strength, which he demonstrated in a spar with Kakashi. As Sasuke and Naruto began another intense training session, a secret letter arrived for Senju Kenya.

• A white snake delivered a sealed top-secret letter, and Kato Yosuke picked it up and hurried to Senju Kenya.

Senju Kenya received a groveling cooperation offer from Orochimaru, who promised research assets and White Zetsu in exchange for protection and a role in Kenya’s organization. Kenya decided to visit Orochimaru’s hidden laboratory, bringing Zabuza with him.

• Kato Yosuke delivered Orochimaru’s snakeskin letter to Kenya, and Sasuke and Naruto stopped their training when they heard Orochimaru’s name.
• Kenya read Orochimaru’s apology and pledge of allegiance, then laughed at the Sannin’s sudden submission.
• Orochimaru offered his laboratories, Hashirama-cell research, sword blanks, forbidden techniques, and captured White Zetsu as part of a collaboration proposal.
• Yosuke warned Kenya that Orochimaru’s offer could be a trap, but Kenya dismissed the danger and threatened to destroy the laboratory if Orochimaru betrayed him.
• Kenya told Yosuke to watch the house and ordered Zabuza to accompany him; half a day later, they reached a hidden cavern near the Land of Rice Fields’ border.

Senju Kenya broke into Orochimaru's underground base, where the terrified Orochimaru showed him a dangerous living specimen called White Zetsu. Kenya studied the creature with interest, leaving its fate unresolved.

• Kenya watched White Zetsu writhe in its tank with a gleam of interest in his eyes.

White Zetsu’s cells ran wild during Orochimaru’s experiment, threatening to destroy the underground laboratory. Kenya subdued the monster with brute force and Senju life force, leaving it transformed into a docile lump of pure living flesh and Orochimaru stunned.

• White Zetsu’s uncontrolled growth shattered its cultivation tank and sent thorny tentacles thrashing through the laboratory.
• Kabuto urged Orochimaru to activate the laboratory’s self-destruct barrier and release poison gas, but Kenya stepped in before Orochimaru could act.
• Kenya blocked White Zetsu’s attacks with his body, grabbed its head, and beat it with repeated slaps.
• White Zetsu’s malignant growth receded under Kenya’s force until it shrank into a harmless, fist-sized lump of living flesh.
• Orochimaru sank among the broken glass, stunned by Kenya’s transformation of the specimen.

Orochimaru joined Iron Fist Heavy Industries after Kenya purified the White Zetsu cells, and Kenya assigned him ambitious medical, armor, and anti-stealth projects. As Kenya prepared to return to Konoha, Zabuza received an urgent plea for help from Mei Terumi.

Karatachi Yagura confessed that Madara Uchiha had controlled him, relinquished the Mizukage position, and Mei accepted the hat and formally sealed an alliance with Kenya.

• Ao’s Byakugan revealed overwhelming physical vitality in Kenya, and a faint surge of Kenya’s energy rushed back through Ao’s eye.

• A lightning-wreathed messenger hawk flew at the observation tower, and Kenya caught it and took its thunder-gold scroll.
• Mei Terumi read the Fourth Raikage A's letter, which accused Kenya of destabilizing the great nations and demanded an emergency Five Kage Summit in the Land of Iron within three days.
