Chapter Summaries

Kenichi Amamiya tested rice with a durian-like flavor and ordered more experiments to improve its high-yield seeds. He then turned to research on the Sharingan, while Obito learned that Shisui Uchiha had led some Uchiha away from Konoha and agreed to search for them in case his missing eye was among them.

• Kenichi Amamiya found the pungent, durian-flavored rice surprisingly edible and judged its much higher yield worth the unusual taste.
• Kenichi Amamiya ordered the rice variety to be planted and used as a sample for further gene-mutation experiments.
• A Shadow Clone handed Kenichi Amamiya a bottle of hydrofluoric acid, and he postponed testing it while planning further Sharingan research.
• Obito learned from Black Zetsu that Shisui Uchiha had led part of the Uchiha Clan in defecting from Konoha.
• Obito initially dismissed the defectors but agreed to have Black Zetsu search for them after Black Zetsu suggested his missing eye might be with them.

Kenichi Amamiya’s attempt to extract elemental fluorine with Lightning Release ended in an explosion, so he planned to obtain potassium fluoride and try electrolysis again. After helping Sasori and Deidara clean up their own explosive puppet experiment, he decided to visit Itachi Uchiha and Sasuke Uchiha to check on them.

• Kenichi Amamiya’s direct electrolysis of hydrogen fluoride caused an explosion that damaged his laboratory, so he decided to seek potassium fluoride and retry the process.
• Kenichi Amamiya heard a series of blasts from Sasori and Deidara’s area and hurried over to help them collect scattered puppet components.
• Deidara explained that he and Sasori had tried to install Clay Bombs in a puppet, but their experiment had turned it into an unstable suicide weapon.
• Kenichi Amamiya suggested ways to make the Clay Bombs safer and proposed drone tactics, but Sasori chose to keep working on giant mechanical puppets.
• After another small explosion, Kenichi Amamiya worried about the altered Timeline of Itachi Uchiha and Sasuke Uchiha and decided to visit them.

Kenichi Amamiya visited the Uchiha settlement and saw how the clan had built a peaceful village, then checked on Itachi Uchiha and Sasuke Uchiha. After finding Sasuke at school, Kenichi proposed taking him with him, leaving Shisui Uchiha startled.

• Kenichi Amamiya arrived at the expanded Uchiha settlement and spoke with Shisui Uchiha about the clan’s new life and future obligations.
• Shisui Uchiha took Kenichi to see Itachi Uchiha, who had awakened the Three Tomoe Sharingan and shown Kenichi his crow Summoning Beast.
• Kenichi reflected on how Itachi’s departure from Konoha had changed the likely course of the Uchiha Clan’s future.
• Kenichi and Shisui found Sasuke Uchiha attending a small clan school, where Shisui admitted the Uchiha had not revealed their ninja identities to the refugees.
• Kenichi asked Shisui whether he could take Sasuke with him, and Shisui reacted with surprise.

Kenichi Amamiya offered to train Sasuke, then returned to his laboratory to investigate why transplanted Sharingan could not be deactivated. His experiment confirmed that an eye connected without the Uchiha’s three extra nerves remained active and drained Chakra, so he proposed transplanting those nerves next.

• Kenichi Amamiya asked to train Sasuke, but Shisui Uchiha said he would first ask Sasuke what he wanted.
• Kenichi Amamiya returned to his laboratory and told Orochimaru he had found three extra nerves in Uchiha eyes that might control the Sharingan.
• Orochimaru joined Kenichi Amamiya as he transplanted a Sharingan into a Root test subject while leaving the three nerves unconnected.
• The test subject could use the Sharingan but could not deactivate it, and the eye continuously consumed his Chakra.
• Kenichi Amamiya proposed transplanting the three Uchiha nerves into the test subject to see whether that would solve the problem.

Kenichi Amamiya performed a Sharingan transplant on a Genin, connecting the eye’s nerves to the subject’s brain and successfully teaching him to deactivate the Sharingan. He began checking whether the subject could also stop the eye from consuming Chakra.

• Kenichi Amamiya removed the subject’s optic nerves and used a ninjutsu he had learned from Orochimaru to connect them to the Genin’s brain.
• Kenichi Amamiya placed the Sharingan in the subject’s eye socket, connected its nerves and blood vessels, and healed the eye with Medical Ninjutsu.
• Orochimaru recorded the experiment as Kenichi Amamiya tested the subject’s vision and condition after the transplant.
• Kenichi Amamiya guided the subject to focus Chakra in his eye, and the Genin changed his One-Tomoe Sharingan back into an ordinary eye.
• Kenichi Amamiya asked whether the subject could still feel Chakra being consumed by the eye.

Kenichi Amamiya and Orochimaru confirmed that their eye-transplant method let a non-Uchiha control the Sharingan, but each successful transplant cost an Uchiha pair of eyes. Kenichi considered an even more disturbing way to produce Sharingan repeatedly and began testing whether an Uchiha could awaken new eyes after receiving ordinary ones.

• A test subject confirmed that his transplanted Sharingan no longer drained his Chakra, and Orochimaru praised Kenichi Amamiya’s solution.
• Kenichi Amamiya explained that the method required sacrificing one Uchiha for each person given controllable Sharingan, and he warned that the Uchiha Clan’s limited numbers made it vulnerable to exploitation.
• Orochimaru judged that the Uchiha Clan would eventually be eliminated unless it produced someone as strong as Madara Uchiha.
• Kenichi Amamiya proposed transplanting ordinary eyes into an Uchiha who had already undergone Eye Opening, then using his method to awaken another pair of Sharingan for repeated transplantation.
• Kenichi Amamiya began fitting the test subject’s eyes into the unconscious Uchiha so he could observe whether the transplant caused a Rejection Reaction.

Kenichi Amamiya experimented on an Uchiha test subject and continued researching how bloodlines affected eye evolution. After Nagato offered him and Orochimaru a mission in the Land of Snow to find a vanished scientist and collect chakra-absorbing metal, Kenichi planned to take Orochimaru there by airship.

• Kenichi Amamiya connected three substitute nerves from the test subject's arm to his Sharingan eye, then sent him to recover before further experiments.
• Kenichi's genetic experiments on lab mice continued to fail, prompting him to consider whether closer ties to the Otsutsuki Clan enabled greater eye evolution.
• Nagato contacted Kenichi and Orochimaru about a bounty from the Snow Ninja Village to find the scientist who developed chakra-absorbing alloy.
• Kenichi and Orochimaru accepted the mission, and Kenichi proposed flying to the Land of Snow in his airship.
• Orochimaru agreed to travel with Kenichi after he invited her to come along.

Kenichi showed Orochimaru how his hot-air airship worked and discussed adapting the Sky Ninja Village’s flying tools into faster Chakra-powered aircraft. Meanwhile, Obito learned that part of Rin Nohara’s corpse was missing and flew into a rage.

• Kenichi confirmed that his airship used hot air for lift, demonstrated its Fire and Wind Release systems, and took Orochimaru into the sky.
• Orochimaru asked Kenichi about the airship’s design and considered ways to develop hot-air flight further.
• Kenichi proposed enlarging the Sky Ninja Village’s single-person flying tools into Chakra-powered Fighter Jets, and Orochimaru began experimenting with the idea.
• Obito asked Black Zetsu about Akatsuki’s progress while keeping the Fourth Mizukage under control and maintaining Kirigakure’s Bloody Mist Policy.
• Black Zetsu revealed that part of Rin Nohara’s corpse was missing, and Obito’s eyes turned blood-red.

Obito learned that one of Rin Nohara’s hands had been stolen from her grave and searched for answers after venting his anger. Meanwhile, Kenichi Amamiya and Orochimaru reached the Land of Snow to investigate the missing scientist and prepare to meet the Snow Kage.

• Black Zetsu told Obito that one of Rin Nohara’s hands was missing from her grave, and Obito flew into a rage.
• Obito calmed down at sea and asked Black Zetsu who had taken Rin’s hand, but Black Zetsu said he had found no traces.
• Kenichi Amamiya spotted the snowfields of the Land of Snow from the airship and noticed Orochimaru’s rough model of a jet engine.
• Kenichi Amamiya and Orochimaru jumped from the airship and landed safely in the snow using Wind Release.
• Kenichi Amamiya recalled the Land of Snow’s legendary heater and decided they should first visit Snow Ninja Village to ask the Snow Kage about the mission.

Kenichi Amamiya and Orochimaru explored the snowy Land of Snow, where Kenichi discovered a carnivorous plant that trapped prey with paralyzing thorns and relied on spiders to digest it. He collected samples of the plant’s thorns to study their anesthetic and cold-resistant properties.

• Kenichi Amamiya and Orochimaru traveled through the Land of Snow while searching primarily for Chakra-absorbing metal.
• Kenichi Amamiya found a thorn-covered plant beneath the snow, surrounded by the bones of animals, and suspected its thorns could paralyze prey.
• Kenichi Amamiya collected liquid from a cut thorn, then tested a thorn on a rabbit that Orochimaru had caught.
• Kenichi Amamiya and Orochimaru watched spider-like creatures swarm over the paralyzed rabbit, dissolve it with digestive fluid, and return some fluid to the plant.
• Kenichi Amamiya cut off several thorns to take back for research into their anesthetic and cold-resistant properties.

Kenichi Amamiya tested Yellow Springs Flower Poison on a Snow Ninja in the Land of Snow’s crowded capital, then stole the hospital’s research records. He and Orochimaru reached their client, Kazahana Dōtō, who served as both the Land of Snow’s Daimyo and Snow Kage.

• Kenichi Amamiya extracted the liquid from a thorny plant and discussed unusual creatures with Orochimaru.
• Kenichi Amamiya and Orochimaru entered the capital of the Land of Snow, where they found a vast, crowded city warmed by hot springs.
• Kenichi Amamiya secretly injected a passing Snow Ninja with Yellow Springs Flower Poison and watched him collapse.
• Medical Ninjas treated the Snow Ninja, and Kenichi Amamiya learned the poison’s name before stealing the hospital’s related research materials and reports.
• Kenichi Amamiya and Orochimaru met their client, Kazahana Dōtō, the Daimyo of the Land of Snow and Snow Kage, who asked if they belonged to Akatsuki.

Kenichi Amamiya accepted a mission in the Land of Snow to find Amado Sanzu and Kazahana Koyuki, while hoping to learn about the country’s great secret treasure. He spotted the disguised Kakashi Hatake in the capital and decided that following him might lead to Koyuki.

• Kazahana Dōtō hired Kenichi Amamiya and his teacher to find the missing scientist Amado Sanzu.
• Kenichi Amamiya prompted Kazahana Dōtō to reveal that his niece, Kazahana Koyuki, had also fled, and Dōtō offered a second commission to find her.
• Kenichi Amamiya left the Snow Kage Building with his teacher, who assigned him to search for the missing people while she looked for Chakra-absorbing metal.
• Kenichi Amamiya spotted the disguised Kakashi Hatake in the capital and considered following him to find Kazahana Koyuki.

Kakashi investigated the Land of Snow’s new Daimyo and Kage, but realized Konoha would probably ignore the information. He bought Icha Icha Paradise and another of Jiraiya’s books, while Kenichi Amamiya decided he might need to replace Kakashi’s eye to help him regain strength.

• After disturbing Rin Nohara’s and Obito Uchiha’s graves, Kakashi was questioned by Third, then sent to the Land of Snow to investigate its ninja village.
• Kakashi learned that the Land of Snow’s Daimyo and Kage had both been replaced, but believed Konoha would not value the intelligence.
• Kakashi bought Icha Icha Paradise and Jiraiya’s book about Orohime from a bookstore.
• Kenichi Amamiya watched Kakashi leave with the books and realized that digging out Kakashi’s Mangekyo had left him unable to use Kamui.
• Kenichi decided he might capture Kakashi and replace his eye so Kakashi could control it and improve his strength.

Kenichi followed Kakashi through the Land of Snow and watched him come to Kazahana Koyuki’s aid, then revealed himself when Kakashi was overwhelmed by three enemy ninjas. The friends reunited, but Kakashi remembered Kenichi’s status as a rogue ninja as they drove off their attackers.

• Kenichi followed Kakashi toward the harbor and saw Kazahana Koyuki flee toward him while pursued by several adults.
• Kakashi chose to protect Koyuki, but his low Chakra and the enemies’ teamwork put him at a disadvantage.
• Kenichi changed out of his Akatsuki-associated clothes and mask, then intervened with a lightning attack.
• Kakashi recognized Kenichi and was happy to see his old friend, though he remembered that Kenichi was an S-Rank rogue ninja wanted by Konoha.
• Kenichi used Great Fireball and Great Fire Annihilation to help Kakashi repel the three enemy ninjas, who fled.

Kenichi Amamiya reunited with Kakashi in the Land of Snow and admitted he wanted to build an ideal nation there. After his Shadow Clone was destroyed while trying to capture Kazahana Koyuki, Kenichi attempted to use Sage Chakra to sense her through the falling snow, but his effort produced giant hailstones instead.

• Kenichi Amamiya greeted Kakashi, who questioned why he had come to the Land of Snow and suspected his presence was tied to the country's upheaval.
• Kenichi told Kakashi he planned to build an ideal nation in the Land of Snow, and Kakashi doubted him.
• Kenichi sensed that his Shadow Clone had been destroyed and rushed to the harbor, where Kazahana Koyuki and the older man who had defeated the clone were gone.
• Kenichi failed to locate them with a basic sensory technique and decided to adapt the Rain Tiger at Will Technique to sense through snow.
• Kenichi poured Sage Chakra into the clouds, but the snowfall stopped; when he increased the Chakra, giant hailstones began falling.

Kenichi Amamiya’s attempt to develop a sensory ninjutsu unleashed enormous hailstones across the port, and he and Kakashi narrowly escaped an explosion. Kenichi tracked the suspected bomber outside the port and demanded to know where Kazahana Koyuki was.

• Kenichi Amamiya’s new ninjutsu caused massive hailstones to strike the port, killing and injuring people and driving them to seek shelter.
• Kakashi questioned whether Kenichi’s destructive technique could really be called a sensory ninjutsu, while Kenichi worried that the hail might have harmed Kazahana Koyuki.
• Kenichi smelled black powder and pulled Kakashi out of their building just before it exploded.
• Kenichi used his Sharingan to spot a fleeing figure and chased him outside the port.
• Kenichi confronted a well-dressed elderly man and asked where the little girl was.

Kenichi Amamiya and Kakashi fought an old man who used a virtual projection and explosives while Kenichi tried to capture a girl with a secret that could change the country. Kenichi poisoned and cornered the old man, but the chapter ended when something stabbed him in the abdomen.

• Kenichi Amamiya told Kakashi that the girl carried a secret that could change the country and continued confronting the old man who had stopped him.
• The old man attacked with a piercing noise, and Kenichi Amamiya answered with a Sage Art-enhanced Great Fire Annihilation that engulfed him.
• Kakashi rushed the old man's apparent body with Chidori, but Kenichi Amamiya warned him that it was a fake and obscured the area with the Hiding in Mist Technique.
• Kenichi Amamiya identified the apparent body as a virtual projection and avoided an explosive trap by using a Shadow Clone.
• Kenichi Amamiya poisoned the old man with Yellow Springs Flower poison and held a kunai to his throat, but something stabbed Kenichi in the abdomen.

Kenichi Amamiya and Kakashi fought an old man who could reflect ninjutsu before Kenichi recognized him as Amado Sanzu, the wanted Chief Scientist of the Land of Snow. The two scientists sat down to discuss their work, leaving Kakashi bewildered by their sudden conversation over coffee.

• Kenichi Amamiya discovered that the old man's earlier appearance had been a Shadow Clone and faced him in the fog.
• The old man identified Kenichi Amamiya's Lightning Release Chakra, while Kenichi noticed his unusual eyes and suspected they were prosthetic.
• Kakashi attacked with the Great Fireball Technique, but the old man reflected it with a tuning-fork-like device.
• Kenichi Amamiya recognized the old man as Amado Sanzu, and Amado confirmed that the Daimyo Kazahana Dōtō had put a bounty on him.
• Kenichi Amamiya invited Amado Sanzu to sit, and the two scientists chatted while Amado brewed coffee for them and Kakashi.

Kenichi Amamiya discussed whether someone remained the same person after losing their memories with Amado Sanzu, who revealed that his friend had changed completely before dying. Kenichi offered to revive the friend temporarily with Impure World Reincarnation, leaving Amado to consider the proposal.

• Amado Sanzu asked Kenichi Amamiya whether a person with the same body but different memories was still the same person.
• Kenichi explained that identity could be complicated by different memories and personalities, then asked why Amado wanted to know.
• Amado said his close friend had lost his memories to an illness, developed a completely different personality, and later died.
• Kenichi offered to use Impure World Reincarnation to bring Amado's friend back temporarily if Amado could provide the friend's body tissue.
• Amado asked whether tissue from a clone would work, and Kenichi said it had to come from the deceased himself.
• Kakashi, uneasy about the conversation, moved aside while considering whether he needed to report it to the Hokage.

Kenichi Amamiya used Impure World Reincarnation to bring Amado Sanzu’s daughter, Akebi, back to life while considering how to recruit Amado and use his Ninjutsu Rebound Device. A sharp rise in the price of ninja tools led Kenichi to suspect that the Uchiha Clan was preparing to act.

• Amado Sanzu revealed that he wanted Kenichi Amamiya to resurrect his deceased daughter and provided a Land of Snow ninja as the living sacrifice.
• Kenichi Amamiya performed Impure World Reincarnation, and Akebi emerged from the coffin and reunited with Amado.
• Kenichi Amamiya discussed recruiting Amado Sanzu with Kakashi, hoping to apply the Ninjutsu Rebound Device’s technology to protect their base or airship.
• Kenichi Amamiya asked Kakashi about Konoha’s situation and learned that ninja tool prices had risen sharply.
• Kenichi Amamiya reasoned that the price increase might mean the Uchiha Clan had begun buying up supplies.
