• Kenichi Amamiya decided to look into Anko’s situation and considered visiting the young Naruto Uzumaki.

Kenichi Amamiya found Naruto being watched and despised by Konoha residents, then tracked Shinnō to Konoha Hospital. He exposed himself as a rogue and confronted Shinnō, prompting the Uchiha Police Force to arrive as he prepared to seek information about his junior sister.

• Kenichi Amamiya learned that Shinnō was treating patients at Konoha Hospital and that Naruto lived nearby, where villagers openly cursed him while shinobi watched over him.

Kenichi Amamiya confronted Shinnō in Konoha, exposed him as the leader of the Sky Ninja Village, and defeated him. After revealing his identity to Hiruzen Sarutobi and demanding to know where Anko Mitarashi was, Kenichi held Konoha’s residents hostage with a Lightning Dragon, but Danzo attacked him from behind.

• Danzo and Root appeared behind Konoha Hospital as Kenichi demanded that Hiruzen hand over Anko Mitarashi or face his Lightning Dragon.
• Hiruzen’s fighters attacked Kenichi, who unleashed the Lightning Dragon; it broke Konoha’s Defense Barrier before Danzo and the others stopped it from causing major damage.
• Kenichi summoned a second Lightning Dragon, and Hiruzen, realizing his estimate of Kenichi’s strength was wrong, agreed to let him take Anko and Shinnō.
• Kakashi brought Anko to Kenichi, who apologized to Kakashi, then left Konoha carrying Anko and the half-dead Shinnō.
• Kenichi sent the Lightning Dragon into a distant mountain, while Hiruzen ordered a Rogue Ninja rank and pursuit order for him and rejected Danzo’s objections.

Kenichi Amamiya freed Anko Mitarashi from the seals suppressing her memories and took her away from Konoha. Anko chose to rejoin her teacher and senior brother, unaware that Kenichi also expected her to earn money for their research.

• Kenichi welcomed Anko while privately planning to rely on her to earn money for their research.

Kenichi Amamiya brought Anko Mitarashi to Anker, where he discussed the fortress’s failing power system and plans with Sasori. He decided to dismantle Anker and take its energy conversion device, while considering the contrasting possibilities of Mechanical and Biological Ascension.

• Kenichi Amamiya introduced Anko Mitarashi to Sasori and handed the gravely wounded Shinnō to the medical team.
• Anko Mitarashi secretly admired Sasori, while Sasori mistakenly thought she wanted treatment for hemorrhoids.
• Sasori explained that Anker’s system could not use Nine-Tails Chakra and that Zero-Tails would take years to grow enough to power the fortress.
• Kenichi Amamiya decided to dismantle Anker and take its energy conversion device with them.
• Kenichi Amamiya reflected on Sasori’s Mechanical Ascension and described Biological Ascension as a more difficult path based on improving genes.

Kenichi Amamiya and Sasori left Anker after Anko Mitarashi killed the technicians, then traveled toward the Land of Rain. Along the way, Kenichi heard that Orochimaru had fought Jiraiya in the Land of Rice Fields, and he learned that Konoha had classified Anko as a B-rank Rogue Ninja.

• Kenichi Amamiya ordered the technicians killed except for the highest-ranking researcher, and Anko Mitarashi volunteered to carry out the killings.
• Kenichi found Shinnō dead, took his mutated arm, and ordered the body burned.

Nagato and Konan discussed Kenichi Amamiya’s delayed return to Akatsuki, and Kenichi reported earning a large payment from Iwagakure through a deal with the Third Tsuchikage. After they discussed the risks of provoking other villages, Kenichi revealed he had noticed Nagato’s Rain Tiger at Will Technique and wanted to learn it.

• Nagato and Konan reflected on the rainy season and Yahiko’s death before Konan asked where Gyokunyo was.

• Kenichi gave Nagato a Sealing Scroll containing Akatsuki’s share of the 745 million ryō he had negotiated from the Third Tsuchikage.
• Nagato questioned whether Kenichi’s actions might unite Konoha and Kumogakure against Akatsuki, but Kenichi argued that such cooperation was unlikely.
• Kenichi told Nagato he had detected Chakra in Amegakure’s rain and asked about the Rain Tiger at Will Technique.

Kenichi Amamiya brought Anko Mitarashi and the captured Koji Tadokoro to the Land of Rice Fields, where he reunited with Orochimaru and met Kimimaro. After hearing about Sky Ninja Village’s flying fortress and Zero-Tails, Orochimaru dismissed Zero-Tails as junk.

• Kenichi Amamiya refused to trade a chance to research the Demonic Statue of the Outer Path for the Rain Tiger at Will Technique and decided to take Anko Mitarashi to his base in the Land of Rice Fields.
• Kenichi Amamiya recruited the captured Koji Tadokoro to help build a Sky Base, though he refused to pay him a salary.
• Kenichi Amamiya arrived at Orochimaru’s laboratory and met Kimimaro, who said Orochimaru had told him about Kenichi.
• Orochimaru emerged and reunited with Anko Mitarashi, who noticed his pectoral muscles seemed unusually large before he ushered her inside.
• Kenichi Amamiya explained Sky Ninja Village’s flying fortress and Zero-Tails to Orochimaru, who said Zero-Tails was junk.

Kenichi Amamiya learned that Zero-Tails was a flawed ancient Konoha creation and checked on his Shadow Clones’ crop research. After absorbing their accumulated fatigue, he conceived a new experiment: stimulating the brain to trigger the intense grief that could awaken the Sharingan.

• Orochimaru explained that Konoha had abandoned Zero-Tails after discovering its limitations, and Kenichi Amamiya concluded the Sky Ninja Village had mistaken a defective relic for a powerful trump card.
• Kenichi Amamiya asked whether Nine-Tails Chakra could be used as energy, but Orochimaru said extracting it would be extremely difficult.
• Kenichi Amamiya returned from Orochimaru’s laboratory and found that his Shadow Clones were still tending the rice fields and waiting for results.
• Kenichi Amamiya dispelled the Shadow Clones and felt their accumulated exhaustion return to him.
• Kenichi Amamiya wondered whether a Shadow Clone’s sensations could overwhelm an enemy when it dispersed, then developed the idea of stimulating the brain to induce extreme sorrow and awaken the Sharingan.

Kenichi Amamiya investigated how Chakra affected Thermobaric Explosive, repeatedly testing different Chakra natures in his laboratory. After months of failed attempts to fuse them, he checked on his rice experiments and learned that sample 23-C had grown noticeably thicker than the others.

• Kenichi Amamiya considered luring an Uchiha to study the Sharingan and its evolution, but decided it was too soon to return to Konoha.
• Kenichi Amamiya prepared small amounts of Thermobaric Explosive and tested how injected Fire Release Chakra affected it in a blast-proof chamber.
• Kenichi Amamiya observed recurring patterns after injecting Fire Release Chakra, found that other Chakra natures produced different patterns, and recorded his results.
• Kenichi Amamiya spent more than three months testing ways to fuse Chakra with Thermobaric Explosive, but his attempts failed and he ran out of materials.
• Kenichi Amamiya checked the rice plants, and his Shadow Clone reported that sample 23-C was noticeably thicker and more vigorous.

Kenichi Amamiya continued his rice-yield experiment, then traveled to Konoha to obtain Uchiha Clan members for research before the clan's population dwindled. Along the way, his attempt to improve the Rasengan failed, and he speculated that Otsutsuki genetics might affect reincarnation and paternity; he entered Konoha under an assumed identity and found security tighter than before.

• Kenichi Amamiya inspected Sample 23's unusually large rice plants and told his Shadow Clone to tend them and calculate their eventual yield.
• Kenichi Amamiya left for Konoha to acquire experimental subjects from the Uchiha Clan, worried that Clan Annihilation Night might happen early.
• Kenichi Amamiya tried combining Wind and Lightning Chakra in a Rasengan, but the resulting explosion destroyed his carriage.
• Kenichi Amamiya theorized that Otsutsuki Genetic Information could enable Kekkei Mōra and wondered whether reincarnation could alter Naruto and Sasuke's DNA.
• Kenichi Amamiya changed identities, passed Konoha's stricter gate inspection, and noticed Uchiha Clan Members among the guards.

Kenichi Amamiya visited Konoha, witnessed Naruto Uzumaki being ostracized, and then scouted the Uchiha district for people to abduct for his Sharingan experiment. He identified seven potential subjects but had not yet figured out how to take them away.

• Kenichi Amamiya ate at Ichiraku Ramen and heard Villagers complain about the Uchiha Police Force.
• Naruto Uzumaki arrived, was shunned by the Villagers, and had a rotten egg thrown into his ramen while Ichiraku replaced the bowl.
• Kenichi Amamiya watched Mikoto Uchiha and Sasuke Uchiha observe Naruto before deciding not to interfere.
• Kenichi Amamiya went to the Uchiha district and searched for Sharingan users to abduct for his experiment.
• Kenichi Amamiya chose six Uchiha at an oden stall and the stall owner with a One Tomoe Sharingan as his seven targets, but struggled to plan their abduction.

Kenichi Amamiya tried to smuggle Uchiha clan members out of Konoha, impersonating a Root ninja to enlist Shisui Uchiha’s help. After Shisui grew suspicious, Kenichi attacked the clan compound, seized six Uchiha, and fled toward the border, where Shisui intercepted him.

• Kenichi planned to control Uchiha clan members with his Sharingan and take them out of Konoha before using a hot air balloon.
• Shisui mistook Kenichi for a Root ninja, and Kenichi gave him a false mission and showed him a wooden token to pass Shisui’s identity check.
• Kenichi followed Shisui when he ran toward another location, then sent a Shadow Clone to attack the Uchiha compound as a diversion.
• Kenichi used the Nirvana Temple Technique and Sharingan to control six Uchiha at an oden stall, killed one whose control proved unstable, and headed for the border.
• Shisui caught up with Kenichi and attacked, while Kenichi revealed his Three-Tomoe Sharingan and claimed he wanted to preserve the Uchiha bloodline by taking them away.

Kenichi Amamiya persuaded Shisui Uchiha to abandon hopes of reconciling Konoha and the Uchiha Clan and help build a new ninja village. Shisui returned to Konoha to quietly recruit clan members, while Kenichi waited at the Valley of the End and planned experiments on the Sharingan.

• Kenichi Amamiya urged Shisui Uchiha to leave Konoha, then escaped the village with captured Uchiha as Shisui followed him.
• Kenichi admitted his Sharingan experiments could put the captured Uchiha at risk, though success might end the Sharingan's curse.
• At the Valley of the End, Kenichi argued that Hiruzen Sarutobi and Danzo would never accept the Uchiha Clan as equals.
• Shisui agreed to join Kenichi in building a new ninja village and to recruit willing Uchiha Clan Members in secret.
• Kenichi warned Shisui to hide his Mangekyō Sharingan from Danzo and set a meeting for three months later.

Kenichi Amamiya removed an Uchiha Ninja’s brain and studied how chakra affected his emotions and Sharingan. After Yang Release Chakra made the subject laugh uncontrollably, Kenichi Amamiya considered trying Yin Release Chakra instead.

• Kenichi Amamiya chose an Uchiha Ninja as his first test subject and used a ninjutsu from his teacher’s book to remove the man’s brain into a vessel of Nutrient Solution.
• Kenichi Amamiya woke the Uchiha Ninja and found that his senses and movement appeared intact, then showed him a mirror to record his brainwave response.
• The Uchiha Ninja’s terror triggered a One Tomoe Sharingan, but Kenichi Amamiya wondered why the shock had not evolved it further.
• Kenichi Amamiya stimulated the Uchiha Ninja’s amygdala with Yang Release Chakra, causing him to laugh uncontrollably despite his despair.
• Kenichi Amamiya admitted his mistake and wondered whether Yin Release Chakra could stimulate grief instead.

Kenichi Amamiya experimented on captured Uchiha Ninja by injecting Yin Release Chakra, but the test subject died without advancing his Sharingan. Comparing the dead Uchiha’s brain with an ordinary person’s, Kenichi discovered a tiny unusual growth in the amygdala and chose Shin Uchiha for his next experiment.

• Kenichi Amamiya injected Yin Release Chakra into an Uchiha Ninja’s amygdala, provoking fear, mania, and abnormal brainwaves before the man died without gaining a two-Tomoe Sharingan.
• Kenichi dissected the dead Uchiha and compared his brain with an ordinary test subject’s while the captured Uchiha Ninja watched in terror.
• Kenichi questioned the prisoners and learned that four had One Tomoe Sharingan, while Shiori had not achieved Eye Opening.
• After three days of comparison, Kenichi found a tiny, orderly growth in the Uchiha’s amygdala that was absent from the ordinary brain.
• Kenichi decided to continue experimenting and grabbed Shin Uchiha, the strongest-looking of the remaining prisoners.

Kenichi Amamiya dissected failed Sharingan test subjects and compared Uchiha samples with tissue from Obito Uchiha’s eye to investigate whether genes affected Eye Opening. After running tests in Orochimaru’s laboratory, he left the chapter beginning a detailed comparison of the results.

• Kenichi Amamiya found mutated tissue in the amygdalae of dead test subjects but no clear evidence that emotional stimulation caused Eye Opening.
• Kenichi Amamiya considered whether talent influenced Sharingan development and retrieved a sample from Obito Uchiha’s Three-Tomoe Sharingan for comparison.
• Kenichi Amamiya used Orochimaru’s laboratory equipment to process Obito Uchiha’s sample and blood samples from two other Uchiha Ninja.
• Kenichi Amamiya found Orochimaru asleep, covered her with a blanket, and then discussed buying DNA extraction equipment with her.
• Kenichi Amamiya spent much of his savings on high-end laboratory equipment and compared the Uchiha gene information, suspecting ancestry might influence Mangekyo awakening.

Kenichi Amamiya and Orochimaru compared Obito’s genes with those of two other Uchiha and found that Obito’s sample contained nearly one hundred additional genes. They could not yet tell whether the differences came from the Mangekyo Sharingan or from Shisui Uchiha’s individual traits, so Kenichi planned to gather more samples.

• Kenichi Amamiya asked whether a computer could identify genetic differences automatically, but Orochimaru and he did not know how to program it.
• Kenichi Amamiya and Orochimaru finished comparing Obito’s genes with two other Uchiha samples and found 39,728 detected genes overall.
• Kenichi Amamiya found 278 differences between Obito’s sample and one Uchiha sample, including ninety-eight additional genes, while the other two samples differed by 197 genes.
• Orochimaru asked about the unusual sample, and Kenichi Amamiya claimed he had collected it from Shisui Uchiha during a fight.
• Kenichi Amamiya and Orochimaru considered whether the extra genes were connected to the Mangekyo Sharingan, but lacked enough samples to know.
• Kenichi Amamiya decided to collect more Uchiha blood samples for comparison.

Kenichi and Orochimaru compared the genes of four captured Uchiha Ninja and confirmed that only Number One, Uchiha Shisui, had unusual genetic differences. Kenichi then received Orochimaru’s scroll on Genetic Information Editing Ninjutsu and asked to study a dangerous technique that could alter adults.

• Kenichi drew blood from the four captured Uchiha Ninja, and Uchiha Shiori stayed calm because she believed trembling could be more dangerous than the needle.
• Kenichi and Orochimaru compared the samples and found that the three new samples shared the same amount of genetic difference from Number One.
• Kenichi considered whether the unusual genes could be inserted into adults, but recognized that the procedure would be difficult and risky.
• Orochimaru gave Kenichi a scroll describing Genetic Information Editing Ninjutsu, which only worked during the fetal stage.
• Kenichi asked about a technique that could alter adults, and Orochimaru said one existed but had never been survived; Kenichi asked to study it.
