Chapter Summaries

Kenichi Amamiya investigated Anko Mitarashi after she insisted on returning to Konoha, finding her Chakra unusually increased and a grain of sand hidden in her clothes. He then traveled to the Land of Snow, where Kazahana Koyuki implanted a high-authority parasite in Uchiha Shiori, leaving her convulsing.

• Kenichi Amamiya told Orochimaru his experiment was progressing and left her laboratory to speak with Anko Mitarashi.
• Anko Mitarashi said she wanted to return to Konoha but would not explain why, so Kenichi Amamiya used genjutsu to knock her out and examine her.
• Kenichi Amamiya found no unusual Chakra in Anko Mitarashi’s brain, but noticed her increased Chakra reserves and discovered a grain of sand in her clothes.
• Kenichi Amamiya left Anko Mitarashi with Sasori and flew to the Land of Snow with Uchiha Shiori and two experimental subjects.
• Kazahana Koyuki reported that she had cultivated five Worker Worms, and Kenichi Amamiya ordered her to implant the highest-authority one in Uchiha Shiori.
• Uchiha Shiori opened her mouth for the parasite, which crawled inside before she began convulsing violently.

Kenichi Amamiya observed Uchiha Shiori recover from implantation with an advanced parasite and confirmed it could influence her loyalty without impairing her independent thought. He compared lower-grade parasites, assigned Kazahana Koyuki to cultivate parasite eggs, and prepared to experiment with the Sharingan.

• Kenichi Amamiya recorded Uchiha Shiori’s painful implantation and learned that the parasite could control behavior and influence thoughts while preserving her autonomy.
• Kazahana Koyuki reported that the Land of Snow was stable and its Ninja Academy system was in place, though few residents qualified to become ninjas.
• Uchiha Shiori recovered and behaved normally for a week, while Kenichi Amamiya found that the Byakugan could reveal the parasite on her brain and cervical spine.
• Kenichi Amamiya implanted mid-grade and low-grade parasites in two test subjects and recorded their stronger reactions and shorter implantation times.
• Kenichi Amamiya assigned Kazahana Koyuki to cultivate parasite eggs and prepared to begin the Sharingan experiment.

Kenichi Amamiya tested whether a parasite could survive a host awakening the Three-Tomoe Sharingan and found that even a low-level larva could force its host to kill himself. He continued testing parasites on captured ninja and, while waiting for results, wondered whether spreading Uchiha traits would make the Shinobi World dangerously emotional.

• Kenichi completed a test subject’s awakening of the Three-Tomoe Sharingan and confirmed that the parasite remained unaffected.
• Kenichi ordered the subject to kill himself, and the parasite’s influence drove the man to cut off his own head before it crawled out alive.
• Kenichi fed the larva Chakra, recorded his findings, and had Uchiha Shiori bring him a Genin for another test.
• Kenichi implanted the larva in a restrained female Genin, recorded her pain and convulsions, and later had Shiori take her away once the parasite settled.
• Kenichi spoke with Shiori about her past and her unpopularity in Konoha while he waited to assess the parasite’s long-term stability.
• Kenichi wondered whether giving everyone Uchiha genes would make the world more volatile, then considered Naruto’s genes as an alternative.

Kenichi Amamiya prepared to visit Naruto and obtain Nine-Tails Chakra, but Konoha’s new airships gave him an idea for selling his own airship technology to the other ninja villages. He recruited Orochimaru to help and set out to negotiate, beginning with Sunagakure.

• Kenichi Amamiya wondered whether Naruto had learned to refine Chakra and planned to visit him to study Kurama and replenish Nine-Tails Chakra.
• Hiruzen Sarutobi found Naruto refining Chakra with a method resembling his own, questioned him about who taught it, and decided to strengthen Naruto’s protection.
• Kenichi Amamiya spotted Konoha’s airships and realized he could profit by selling his airship technology to rival ninja villages.
• Kenichi Amamiya asked Orochimaru to join his plan, and Orochimaru agreed while giving him five hundred million for the Sharingan transplantation work.
• Kenichi Amamiya packed his equipment and left with Orochimaru aboard the airship, planning to visit Sunagakure, Iwagakure, Kumogakure, and Kirigakure.

Kenichi Amamiya and Orochimaru traveled to Sunagakure to promote their new technology, including a prototype mobile phone and an airship. The Fourth Kazekage Rasa received Kenichi’s product introduction and considered the airship despite its high cost.

• Orochimaru gave Kenichi Amamiya a prototype mobile phone that could call her over a long distance, and Kenichi suggested using relay stations to extend its range.
• Orochimaru explained that Konoha was targeting weaker Sunagakure for business, and Kenichi agreed that the village was a likely first customer.
• Kenichi flew the airship into Sunagakure and threw a product introduction letter toward the Kazekage Building.
• The Fourth Kazekage Rasa recognized the visitor as the Heavenly Demon and read Kenichi’s pitch for the Airship X237.
• Rasa found the airship tempting as a tool for defense and transport, though its price gave him pause.

Kenichi Amamiya sold Rasa Sunagakure the airship blueprint and a completed airship, refusing to lower the price despite Rasa's attempts to haggle. After the deal, Kenichi and Orochimaru flew toward Iwagakure to sell the technology there as well.

• Kenichi Amamiya and Orochimaru arrived above Sunagakure and invited Rasa to negotiate aboard their airship.
• Rasa boarded with two Anbu ninjas, inspected the airship, and tried to use Konoha's aircraft as leverage for a lower price.
• Kenichi Amamiya refused to discount the blueprint, and Rasa paid for it because Sunagakure could not risk falling behind other villages.
• Rasa bought the airship itself for ten million ryo after Kenichi Amamiya agreed to his counteroffer, then ordered his men to inspect and copy the blueprint.
• Kenichi Amamiya and Orochimaru left in another airship and headed for Iwagakure to continue selling the technology.

Kenichi Amamiya and Orochimaru approached Kumogakure to sell airships, but Killer B and A-Bee attacked them with Tailed Beast Bombs. Their airship was destroyed, leaving Kenichi and Orochimaru under fire from the Raikage’s forces.

• Kenichi Amamiya and Orochimaru left Iwagakure after completing an airship deal, and Kenichi refused the Tsuchikage’s offer to buy exclusive rights.
• Kenichi told Orochimaru that his research into the Uchiha Clan’s genetic modification had advanced, and Orochimaru asked him to perform it for her in exchange for a secret technique.
• Kenichi and Orochimaru neared Kumogakure and found its ninjas using hot air balloons, then Killer B and A-Bee charged toward their airship.
• Killer B transformed and fired a Tailed Beast Bomb, but Kenichi maneuvered the airship away from the blast.
• A lightning-charged attack pierced the airship, and another Tailed Beast Bomb destroyed it as Kenichi and Orochimaru were thrown clear.
• Kenichi cursed Killer B and vowed to beat him until he could no longer rap.

After being blasted into a forest, Kenichi Amamiya uncovered an ancient seal and freed a frightened Uchiha girl with the Mangekyō Sharingan. He took her aboard his airship, and she remembered her name: Uchiha Hikari.

• Kenichi Amamiya escaped Killer B’s attack but landed alone in a remote forest, where his phone stopped working.
• Kenichi Amamiya found an ancient sealing stone and used a method from Orochimaru’s book to open it.
• Kenichi Amamiya discovered a barely breathing girl inside, dressed her, and examined the seal as she gradually woke.
• The girl panicked when Kenichi Amamiya revealed his Sharingan and fled, but he caught up and calmed her.
• Kenichi Amamiya summoned his airship and explained the new era of ninja villages as he took the girl away.
• The girl remembered that her name was Uchiha Hikari.

Kenichi Amamiya rescued Uchiha Hikari, a traumatized girl from the Warring States Period who had been sealed inside a stone, and she decided to stay with him. After comforting and feeding her, he took her to buy clothes and bathe, while planning his next move against Kumogakure.

• Kenichi Amamiya learned Uchiha Hikari had no idea what to do in the modern era and offered to take her to see the Uchiha Clan, but said they first needed to go to Kirigakure.
• Kenichi Amamiya thought of a way to retaliate against Kumogakure after its attack destroyed his airship and nearly killed him.
• Uchiha Hikari asked to follow Kenichi Amamiya, and he comforted her, agreed, and began calling her Hikari.
• Kenichi Amamiya taught Uchiha Hikari how to eat hot pot, and she ate nearly all his food.
• Kenichi Amamiya took Uchiha Hikari to buy clothes and bathe, and she smiled at her reflection for the first time.

Kenichi Amamiya brought Uchiha Hikari to the Land of Snow and left her in Uchiha Shiori and Kazahana Koyuki’s care before heading off to handle dangerous business. He learned that Hikari’s Yachihoko could link and control minds and Chakra across long distances, while he continued planning his Wood Release research.

• Kenichi Amamiya explained that he would leave Uchiha Hikari somewhere safe while he dealt with a risky matter, and she pleaded to go with him and offered to share her Chakra.
• Kenichi Amamiya persuaded Uchiha Hikari to train and wait for him, while considering how to keep her safe from people who might exploit her abilities.
• During their airship journey to the Land of Snow, Kenichi Amamiya learned that Uchiha Hikari’s Yachihoko let her connect to and control marked people’s minds and Chakra and transmit Chakra over any distance.
• Kenichi Amamiya brought Uchiha Hikari to the Land of Snow and entrusted her to Uchiha Shiori and Kazahana Koyuki before leaving.
• Kenichi Amamiya reflected that Uchiha Hikari’s talent made him want to take a disciple, then considered Naruto as his first choice.

Kenichi Amamiya arrived at Kirigakure while searching for his missing teacher and discovered Konoha negotiating to sell hot air balloons. He interrupted the deal as Heavenly Demon, and the chapter ended with Karatachi Yagura arriving to confront him.

• Kenichi Amamiya failed to repair his teacher’s phone and searched Kirigakure for signs of him.
• Shibi Aburame, Kakashi, and Might Guy met Genji outside Kirigakure to negotiate Konoha’s hot air balloon sale.
• Kenichi Amamiya watched the negotiations and considered how to obtain Might Guy’s Eight Gates technique.
• Kenichi Amamiya introduced himself as Heavenly Demon and offered to do business with Kirigakure, angering Shibi Aburame and the Konoha ninja.
• Karatachi Yagura arrived and asked Kenichi Amamiya what he was doing there.

Kenichi Amamiya and Shibi Aburame competed to sell airship technology to Karatachi Yagura, who bought from both of them. Kenichi left with his payment and began plotting how to obtain the Eight Gates Formation, while Shibi and Kakashi encountered a suspicious birdlike sound in the misty forest.

• Kenichi and Shibi refused to demonstrate their aircraft, then competed over price and trade terms as Karatachi Yagura weighed their offers.
• Kenichi offered a more advanced airship for 100 million ryo, and Karatachi agreed to buy both sellers’ products, paying Kenichi from his personal savings.
• Kenichi handed Karatachi a summoning scroll and left, thinking about how to get Might Guy to teach him the Eight Gates Formation and deciding to involve Kakashi.
• Shibi told Kakashi they needed to report Kenichi’s appearance to the Third Hokage, and Kakashi agreed.
• Kakashi and Shibi heard a brief sound like Chidori in the misty forest, so Shibi sent a swarm of insects into the woods to investigate.

Kenichi Amamiya disguised himself as Kakashi and attacked the Konoha envoy group near Kirigakure, then used the journey home to trick Might Guy into teaching him the Eight Gates Formation. He escaped by air after Shibi Aburame uncovered the deception, leaving the real Kakashi captive in the forest.

• Kenichi Amamiya burned through the Aburame Clan's Kikaichū, drawing Shibi Aburame, Kakashi, and the Kirigakure ninja led by Mei Terumi into a search for the attacker.
• Kenichi Amamiya captured the real Kakashi and restrained him with Chakra-draining chains while a disguised version of himself traveled with the envoy group.
• Shibi Aburame questioned the disguised Kakashi and secretly attached a Kikaichū to him, but Kenichi Amamiya kept up his act and deliberately lost a training contest with Might Guy.
• Kenichi Amamiya asked Might Guy to teach him taijutsu, and Might Guy explained the Eight Gates Formation while they rode in a hot air balloon.
• Shibi Aburame realized something was wrong when his Kikaichū lost contact and the balloons came under attack, but Kenichi Amamiya punctured his balloon and flew away after memorizing the technique.

Kenichi Amamiya escaped after clashing with Might Guy and began studying the Eight Gates Formation, while Konoha concluded that he was the Heavenly Demon. He arrived in the Land of Snow, where Uchiha Shiori gave him a report showing the materials for his Mangekyō Sharingan research were nearly ready.

• Shibi Aburame realized the Heavenly Demon had impersonated Kakashi, and Might Guy opened the Sixth Gate and attacked before rushing off to find Kakashi.
• Kenichi Amamiya escaped, retrieved the metal chains used to bind Kakashi, and studied the Eight Gates Formation as a newly unlocked side mission tasked him with researching acupoints and the Gate of Death.
• Kenichi Amamiya learned Kakashi had survived with most of his Chakra drained, then left the Land of Water for the Land of Snow to research the Mangekyō Sharingan.
• Hiruzen Sarutobi, Tsunade, and Shibi Aburame suspected Kenichi Amamiya was the Heavenly Demon, and Tsunade smashed a table in anger after recognizing him.
• Kenichi Amamiya reunited with Uchiha Hikari and Uchiha Shiori in the Land of Snow, then read Shiori's report that the experiment's raw materials were mostly gathered.

Kenichi Amamiya tested whether parasite-assisted emotional stimulation could awaken Yayoi Yumi’s Mangekyō Sharingan, but the experiment left Yayoi apparently dead before his vital signs returned. Yayoi opened his eyes with Three Tomoe still showing, and Kenichi began to suspect the experiment had a cruel consequence.

• Kenichi Amamiya confirmed that the parasite could control Yayoi Yumi, compel him to reveal secrets, and make him attempt suicide before stopping him.
• Kenichi Amamiya began testing his Sharingan stimulation method on Yayoi, but the initial emotional stimulation failed to produce the expected reaction.
• Kenichi Amamiya asked Kazahana Koyuki whether parasites could influence emotions, and she confirmed they could.
• Kenichi Amamiya used parasite-assisted emotional stimulation on Yayoi, increasing the Chakra stimulation to five times its original intensity.
• Yayoi’s heartbeat and Brainwaves flatlined, but his vital signs later returned to normal, and the parasite remained alive.
• Yayoi opened his eyes with Three Tomoe still visible, leaving Kenichi Amamiya to consider a cruel possibility.

Kenichi Amamiya successfully awakened Yayoi Yumi’s Mangekyō Sharingan through intense emotional stimulation while he was conscious, then tested its abilities and began planning a larger experiment in the Land of Snow. He left the laboratory to assess the growing parasite supply and asked Kazahana Koyuki about food reserves for his planned Ninja Legion.

• Kenichi Amamiya concluded that a Mangekyō awakening required intense conscious desire and ordered the parasites to make Yayoi Yumi want to destroy everything.
• Kenichi Amamiya stimulated Yayoi Yumi while he was conscious, and Yayoi Yumi awakened the Mangekyō Sharingan after a strange fluid flowed from the Sharingan Particles in his amygdala.
• Kenichi Amamiya had Uchiha Shiori guard and question Yayoi Yumi, then observed him use Amaterasu and a telekinetic ability before the strain made his eyes bleed.
• Kenichi Amamiya decided to conduct larger trials in the Land of Snow, where he hoped to build a Ninja Legion while keeping his research isolated from other villages.
• Kenichi Amamiya asked Kazahana Koyuki about the parasite eggs and learned they could make roughly half the country hosts, though not all hosts could become ninjas.
• Kenichi Amamiya asked Kazahana Koyuki about food reserves for the planned force.

Kenichi Amamiya recognized that the Land of Snow lacked enough food to support a large ninja army, so he planned to begin with an elite squad. Meanwhile, Jiraiya ran into Orochimaru, who confronted him with an explicit illustrated edition of one of his books.

• Kazahana Koyuki told Kenichi Amamiya that the Land of Snow had only enough food reserves to feed its people for half a year.
• Kenichi Amamiya decided to form a small elite squad, recruit loyal ninja, and use intermediate-grade insect eggs to strengthen them.
• Kazahana Koyuki left to carry out Kenichi Amamiya's orders, eager to discipline disobedient ninja.
• Kenichi Amamiya spent time with Uchiha Hikari and wondered where his missing teacher had gone.
• Jiraiya encountered Orochimaru in the Land of Earth, and Orochimaru showed him an eighteen-plus illustrated edition of Jiraiya's book about Orochimaru.

Orochimaru attacked Jiraiya over his novel, while Kenichi received news of their battle and continued consolidating control in the Land of Snow. In his laboratory, he tried to give Yayoi Yumi a reason to serve the cause by reminding him that ordinary ninja were expendable in war.

• Orochimaru confronted Jiraiya in Tomioka Town, and their fight destroyed the town.
• Kenichi learned that Orochimaru and Jiraiya were fighting, then heard that some Land of Snow clan ninja had refused the parasite eggs.
• Kazahana Koyuki confronted the Yukiri Clan and had Kenichi's Shadow Clone deal with their resistance by force.
• Uchiha Hikari asked Uchiha Shiori whether Kenichi was available, and learned he would have dinner with her later.
• Kenichi examined Yayoi Yumi, who explained that he could no longer control his body or stop himself from speaking.
• Kenichi told Yayoi Yumi that ordinary ninja became cannon fodder in war and that Konoha had sent students onto the battlefield during the Third Great Ninja War.

Kenichi Amamiya questioned Yayoi Yumi about the limits of his Mangekyō Sharingan, then began planning experiments to awaken Sharingan abilities in other ninjas. In Konoha, Tsunade discovered an abnormal growth in Hiruzen Sarutobi’s lungs and read intelligence linking Jiraiya and Orochimaru to a scandalous novel, leaving her furious enough to destroy a bookstore.

• Kenichi Amamiya failed to persuade Yayoi Yumi to embrace his vision of peace, but learned that using Amaterasu required a day of recovery and could temporarily blind him if repeated.
• Kenichi Amamiya recorded that parasite eggs might help develop Sharingan abilities in other ninjas, then went to the laboratory to consider researching a rocket launcher.
• Tsunade found strange tissue in Hiruzen Sarutobi’s lungs, connected it to his coughing and possibly smoking, and agreed to examine Asuma as well.
• Hiruzen Sarutobi showed Tsunade intelligence from Kumogakure linking Jiraiya and Orochimaru to a missing Anbu ninja, a novel called "The Story I Had to Tell About Orohime," and large purchases of stockings.
• Hiruzen Sarutobi secretly bought a book at a bookstore, and Tsunade later destroyed the shop with her Heavenly Foot of Pain while shouting that she would kill Jiraiya.
• Naruto heard Tsunade’s roar outside and worried about spilling the week-expired milk he was drinking.

Kenichi Amamiya tested whether intense emotional stimulation could awaken a Mangekyō Sharingan, using Uchiha Shiori as his first subject. Shiori awakened a spatial ability, and Kenichi prepared to begin experiments on a larger scale.

• Uchiha Shiori told Kenichi Amamiya that the parasites in the Land of Snow shinobi had matured, and he ordered five subjects at a time to be brought to the laboratory.
• Kenichi Amamiya chose Uchiha Shiori as the first Mangekyō subject, anesthetized her, and stimulated her brain while testing whether her Sharingan could evolve without the parasite controlling her thoughts.
• Uchiha Shiori's Sharingan advanced from Two Tomoe to Three Tomoe and then awakened its Mangekyō after further stimulation.
• Uchiha Shiori demonstrated that her left eye could retrieve objects she had touched and her right eye could send objects to remembered places; a Lab Mouse transferred from the base arrived dead.
• Kenichi Amamiya warned Uchiha Shiori not to overuse her Mangekyō and began planning large-scale experiments with his Shadow Clones.
