Chapter Summaries

Kenichi Amamiya studied Hidan’s regenerative arm while continuing his research into Genetic Programming Ninjutsu and Chakra explosives. After successfully growing a useless nose on Hidan’s hand, he began testing whether Yin Release Chakra could erase the inserted genes, but immediately sensed something was wrong.

• Kenichi Amamiya examined Hidan’s severed arm and concluded its healing resembled Wolverine’s rapid regeneration more than simple immortality.
• Kenichi Amamiya resumed researching Chakra explosives, which had reached 3.99% progress, while his Shadow Clone analyzed Hinata Hyuga’s genes.
• Kenichi Amamiya’s experiments on Hidan’s arm produced a nose with no functional airway, and he labeled the inserted genome information as “nose.”
• Kenichi Amamiya found that Yang Release Chakra could not destroy the inserted genes and decided to try Yin Release Chakra instead.
• Kenichi Amamiya began using Yin Release Chakra to erase the nose’s genes and immediately noticed something was wrong.

Kenichi Amamiya accidentally made Hidan’s arm vanish while testing Yin Release, then caused an explosion when his Shadow Clones were abruptly dispelled. He returned to investigating the strange power as Orochimaru set out for Kirigakure to look into an intriguing development.

• Kenichi Amamiya used Yin Release Chakra while trying to erase a gene and watched Hidan’s arm vanish without a trace.
• Kenichi Amamiya realized his Shadow Clones had all been dispelled, then rushed to the blast-proof laboratory when one of their experiments exploded.

• Kenichi Amamiya told Orochimaru about Hidan’s missing arm, and she asked him to retrieve the other one carefully.
• Orochimaru told Kenichi Amamiya she was going to Kirigakure because something interesting had happened there, and he wondered whether Obito had been killed by his bomb.

Kenichi Amamiya spent nearly a year in his laboratory trying to improve Genetic Programming Ninjutsu, eventually reaching a thirty-five percent success rate before his research stalled. He also learned about upheaval in Kirigakure and found that Hinata Hyuga carried unusually pure Hyuga bloodline traits.

• Kenichi Amamiya stayed behind instead of following Orochimaru to Kirigakure, and resumed experiments on Hidan's body.
• Kenichi Amamiya set aside his attempt to use Yin Release Chakra to destroy genes and focused on improving Genetic Programming Ninjutsu.

• After nearly a year, Kenichi Amamiya's progress stalled at thirty-five percent, and he considered leaving the laboratory to find a new approach.
• Orochimaru returned from Kirigakure and told Kenichi Amamiya that the Bloody Mist Policy had stirred widespread unrest, with no reports of a Masked Man being injured.
• Kenichi Amamiya compared Hinata Hyuga's gene analysis with that of a Hyuga Clan Branch Family ninja and concluded that Hinata had a purer bloodline inherited from Otsutsuki Hamura.

Kenichi Amamiya left his laboratory to clear his head and hurried to the Uchiha settlement after mistaking festival smoke for an attack. He found the village celebrating the autumn harvest and recognized the masked Obito Uchiha among the crowd.

• Kenichi Amamiya grew concerned that Obito might obtain another Mangekyō Sharingan, while Obito became suspicious that Kenichi knew his identity.

Kenichi Amamiya told Shisui, Itachi, and Sasuke that the Uchiha Clan had rebelled in Konoha and that Fugaku Uchiha had been captured and executed. Itachi reacted with rage, while Sasuke stood stunned.

• Kenichi Amamiya met Shisui, Itachi, and Sasuke while Obito, disguised as Tobi, eavesdropped nearby.

After learning that Fugaku Uchiha had died, Itachi lost control and nearly set out to attack Konoha, but Kenichi Amamiya and Shisui calmed him by revealing that Fugaku had helped Mikoto and other Uchiha escape. Itachi decided to search for his mother with their help, while Kenichi urged Shisui to consider what the Uchiha should do next.

• Kenichi Amamiya told Shisui and Itachi that Fugaku had been killed and that his eyes had been taken.

• Sasuke asked Naruto if he feared him, and the boys introduced themselves as ninjas while Kenichi secretly recorded them.
• Kenichi heard Naruto’s stomach rumble and realized the boy had not eaten.

• Kenichi Amamiya took Sasuke to buy Dango and avoided investigating Tsunade’s return so he would not attract attention.
• Tsunade examined Hiruzen Sarutobi and told him that something was wrong, though she needed more tests to identify the problem.

Tsunade confronted Kenichi over his political deception, and their fight began with Kenichi using poisoned Fire Release.

• Kenichi Amamiya’s Shadow Clone bargained with Hiruzen Sarutobi, offering benefits in exchange for Mikoto Uchiha, Sasuke, and Fugaku Uchiha’s remains to leave Konoha.

• Kenichi sent Mikoto and Sasuke ahead, but Tsunade accused him of becoming like a politician and attacked him.
• Kenichi entered Sage Mode to face Tsunade, then countered her charge with green-tinged flames and poisoned smoke.

Kenichi Amamiya reunited the escaped Uchiha with their clan, then traveled to the Land of Snow to inspect the Mother Worm growing inside Kazahana Koyuki. He learned it could recombine genes, saw a potential breakthrough for his Genetic Programming research, and provided it with his blood before asking how long the process would take.

• Kenichi Amamiya visited the Underground Complex, where Mikoto Uchiha gathered the escaped Uchiha Clan Members and brought them back to the Land of Rice Fields.
• Kenichi Amamiya left for the Land of Snow, noting that Obito Uchiha had disappeared and might be following Shisui or Itachi.
• Kenichi Amamiya found Kazahana Koyuki governing the Land of Snow and discovered that the Mother Worm had grown tendrils onto her brain and spine.
• The Mother Worm told Kenichi Amamiya it needed exceptional male genetic material and could break down and recombine genes to cultivate offspring.
• Kenichi Amamiya realized the Mother Worm's secretions might help his Genetic Programming research, then gave it his blood so it could extract his genes.

Kenichi Amamiya learned that the mother insect could produce parasites with increasingly powerful abilities, including offspring that might help hosts absorb Natural Energy, and left to test the insect’s secretions in his laboratory. On the way, he found Hiruko trying to capture Pakura and intervened, intrigued by how Hiruko had acquired multiple Kekkei Genkai.

• Kenichi Amamiya asked the mother insect about its offspring and learned that superior parasites could accelerate Chakra refinement, store Chakra, suppress pain, and replace injured body functions.
• The mother insect revealed that its strongest offspring could help hosts absorb a strange energy, and Kenichi Amamiya suspected it was Natural Energy.

• Hiruko trapped Pakura in a Sealing Barrier and used Steel Release and Dark Release to defeat her attacks while boasting about his plan to become immortal.
• Kenichi Amamiya recognized Hiruko and rescued Pakura with Najuuden: Tail Severing, deciding to intervene because Hiruko possessed several Kekkei Genkai.

• Hiruko and Pakura attacked Kenichi with a fireball, a Shadow Clone, and Storm Release lightning spears.
• Kenichi entered Sage Mode, reasoned that Hiruko's lightning depended on the storm clouds, and unleashed a wall of fire toward Hiruko to disperse them.

Kenichi Amamiya defeated Hiruko’s defenses with a massive Fire Release, dispersing the storm clouds and leaving Hiruko alive beside the unconscious Pakura. Hiruko refused to surrender his Chimera Technique outright, but Kenichi found a point of leverage and prepared to take him and Pakura back for further negotiation.

• Kenichi Amamiya’s enormous Fire Release overwhelmed Hiruko’s Storm Release and dispersed the Cumulonimbus Clouds, though Hiruko survived inside a defensive shell.

• Kenichi tried threats and persuasion, but Hiruko insisted he would not hand his life’s work to anyone.

• Kenichi picked up Pakura and told Hiruko they would leave together, while keeping Shisui’s Kotoamatsukami as a possible way to secure the technique.
