Chapter Summaries

Jiraiya told Kenichi Amamiya that a rumor claiming Orochimaru was a woman had inspired him to write a book, and Kenichi worried about how his teacher would react. The chapter left Kenichi face-to-face with Orochimaru, struggling to hide that he had just read a story depicting her seductively.

• Jiraiya told Kenichi Amamiya that a bounty hunter had spread a rumor that Orochimaru was a woman after seeing her face revealed in battle.

• Kenichi brought a man to the base and found Orochimaru there, causing scenes from Jiraiya's book to come back to mind.
• Kenichi looked at Orochimaru's face and golden hair and wondered whether he should confess that he had read the book.

Kenichi Amamiya summoned Hashirama Senju with Impure World Reincarnation, hoping to use his Wood Release to help research faster-growing crops. He tricked Hashirama with a story about Konoha’s food crisis, but Hashirama instead fixated on learning that Minato Namikaze had died.

• Kenichi Amamiya told Orochimaru he planned to use Shadow Clones to research hybrid crops while he focused on the Thermobaric Bomb.
• Orochimaru warned that souls strongly preferred the Pure Land, though Kenichi Amamiya thought Hashirama Senju might agree to help.
• Kenichi Amamiya used Impure World Reincarnation to summon Hashirama Senju.
• Kenichi Amamiya falsely described Konoha as facing destruction and food shortages to persuade Hashirama to use Wood Release for crop research.
• Hashirama Senju reacted in disbelief when Kenichi Amamiya confirmed that Minato Namikaze had died after the Nine-Tails attack.

Kenichi Amamiya summoned Hashirama Senju to ask whether Wood Release could accelerate crop growth, then studied the First Hokage’s techniques and recorded how Chakra output related to their power. He left the data for his Shadow Clones to organize and returned his attention to researching Thermobaric Bombs.

• Hashirama Senju told Kenichi Amamiya that Wood Release could not ripen crops and that he had simply known how to use it.

• Hashirama Senju’s Impure World Reincarnation ran out of Chakra, and Kenichi Amamiya dispelled it.
• Kenichi Amamiya ordered his Shadow Clones to file the collected data and continued researching Thermobaric Bombs.

Kenichi Amamiya gave up on using Wood Release to improve crop growth and asked Orochimaru to build him a laboratory for his research. As Kenichi returned to refining Thermobaric Explosives, Orochimaru dealt with discomfort from his current body and received a summons from Nagato to come to Amegakure.

• Kenichi Amamiya confirmed that Wood Release could not stimulate crop growth, and Orochimaru said that result was expected.
• Kenichi asked Orochimaru to establish a laboratory and invested all but one hundred million of his savings in it.
• Orochimaru asked whether Kenichi wanted to become a village Kage, but Kenichi rejected the idea because it would interfere with his research.
• Kenichi returned to work on Thermobaric Explosive ratios while Orochimaru relieved the pain caused by his body.
• Nagato contacted Orochimaru and told him to come to Amegakure to conduct research.

Kenichi Amamiya tested how different Chakra natures affected thermobaric explosives and found that Senjutsu Chakra made Fire, Wind, and Lightning Release especially effective. He left the valley with a plan to combine those Chakra types using containers or Explosive Tags, but still needed to find a way to hold the Chakra.

• Kenichi Amamiya found Orochimaru gone and took his thermobaric explosives to a deserted valley to test them.
• Kenichi tested ordinary Lightning, Fire, Water, Earth, Yang, and Wind Release Chakra, discovering that Lightning and Fire triggered blasts, Water and Earth were ineffective, Yang had no observable effect, and Wind accelerated the blast.
• Kenichi entered Sage Mode and found that Senjutsu Chakra greatly amplified the effects of Lightning, Fire, and Wind Release; Fire-powered explosives even pierced Rashomon's gate.
• Kenichi concluded that combining Fire, Wind, and Lightning might produce the strongest effect, but recognized that fusing the Chakra types would be difficult.
• Kenichi considered placing Chakra in containers inside the explosives or using Explosive Tags, then packed up his supplies while seeking a suitable way to store Chakra.

Kenichi Amamiya’s attempt to contain Sage Art Chakra in Explosive Tag paper failed, so he considered using costly Chakra-conducting metal and went to inspect a site for his new laboratory. Meanwhile, Obito noticed something unusual about Kakashi’s Sharingan and left to investigate, while Black Zetsu discussed waiting for dissatisfaction with the Fourth Mizukage’s Bloody Mist Policy to grow.

• Kenichi Amamiya reasoned that special Explosive Tag paper might hold Sage Art Chakra, then went to his teacher’s laboratory to test the idea.
• Kakashi visited Obito and Rin Nohara’s graves, while the hidden Obito sensed something was wrong with Kakashi’s Sharingan.
• Black Zetsu told Obito that they could wait for opposition to the Fourth Mizukage’s Bloody Mist Policy to build, and Obito left after deciding to investigate Kakashi’s eye.
• Kenichi Amamiya’s Explosive Tag experiment failed when the paper exploded as soon as it received Sage Art Chakra.
• Kenichi Amamiya decided to consider Chakra-conducting metal and went to meet the construction team assigned to build his laboratory.

Kenichi Amamiya began building a hidden laboratory and tried to develop a Chakra Storage device for a stronger thermobaric bomb, but discovered Sage Art Chakra caused its container to explode. After deciding to seek a weaponsmith’s expertise, he returned to the Black Market and encountered Jiraiya being chased by angry women.

• Kenichi Amamiya hired fifty workers from the Covert Construction Company to hollow out a mountain near his teacher’s laboratory and left two Shadow Clones to supervise them.
• Kenichi Amamiya began developing Thermobaric Bomb Type II and found that Sage Art Chakra made the storage container erupt and explode.
• Kenichi Amamiya decided to consult a professional weaponsmith because he lacked expertise in materials science.
• After more than a week, Kenichi Amamiya returned to the Black Market and saw Jiraiya fleeing from a group of angry women.
• Jiraiya noticed Kenichi Amamiya, who smiled because he had changed his face and expected not to be recognized.

Jiraiya exposed Kenichi Amamiya’s disguise, then asked him whether Orochimaru was a woman. Kenichi dodged the question, accepted Jiraiya’s new book about his teacher, and prepared to leave for the Black Market.

• Jiraiya escaped after passing Kenichi Amamiya a Sealing Scroll and leaving him surrounded by angry women, but Kenichi used the Substitution Technique to get away.

Kenichi Amamiya asked Jiraiya for Mount Myōboku’s Toad Oil to test with Chakra Metal, but Jiraiya refused. Kenichi then visited the Black Market and bought a piece of chakra-absorbing meteorite to investigate as a possible material for his Thermobaric Bomb.

• Kenichi asked Jiraiya whether he could buy Toad Oil, but Jiraiya refused and left after warning him that Sage Mode was dangerous.
• Kenichi disguised himself and entered the Black Market to ask a weapon shop owner about metal that could withstand Sage Art Chakra.
• Kenichi demonstrated that even good Chakra Metal exploded when he infused it with a small amount of Sage Art Chakra.
• The shop owner showed Kenichi a meteorite that absorbed Chakra without exploding when tested with Sage Art Chakra.
• After hearing the meteorite cost one hundred million ryo, Kenichi bought a piece for ten million ryo to test its usefulness.

Kenichi Amamiya examined a meteorite-derived sphere that absorbed Sage Art Chakra, then encountered Orochimaru with the restored Hajun Shin and learned that Orochimaru’s cloning research had advanced. Orochimaru left Kenichi with an experiment log on the Demonic Statue of the Outer Path, which Kenichi began reading with great interest.

• Kenichi Amamiya smelted a meteorite into a quail-egg-sized sphere that absorbed large amounts of Chakra and planned to test its limits outside the laboratory.
• Orochimaru arrived with Hajun Shin, whose arms had been restored, and Kenichi asked whether Orochimaru’s cloning research had advanced.
• Orochimaru confirmed that his research had made progress and handed Kenichi an Experiment Log before leaving with Hajun Shin.
• Kenichi opened the log and discovered it recorded Orochimaru’s research on the Demonic Statue of the Outer Path.

Kenichi tested whether Superconductive Metal could store Sage Art Chakra and amplify a Thermobaric Explosive, successfully creating an entry-level Chakra Thermobaric Bomb. Back at the Lab Base, he found Orochimaru experimenting on Hajun Shin, whose right arm had grown three Sharingan, and learned that he would join his teacher on a mission.

• Kenichi used Sage Art Wind Style Chakra on a Superconductive Metal sphere and found that it released a powerful blast before becoming ordinary, disposable metal.
• Kenichi combined another sphere with a Thermobaric Explosive and Sage Art Fire Release Chakra, producing a stronger explosion and confirming his Chakra Thermobaric Bomb concept worked.
• Kenichi decided to buy more meteorites from the Black Market and test the bomb on a future mission.
• Kenichi returned to the Lab Base and saw Orochimaru testing three Sharingan that had grown on Hajun Shin's right arm.
• Orochimaru told Kenichi that Root's cooperation involved a mission, and Kenichi agreed to go with him.

Kenichi Amamiya accompanied Orochimaru to the Land of Fire’s capital to administer an anti-aging treatment to the Daimyo, whose fear of death and political position made the job unusually sensitive.

Kenichi Amamiya accompanied Orochimaru to the Land of Fire’s capital, where they exchanged documents with Danzo’s Root and met the Daimyo. Orochimaru began explaining the possible side effects of a serum before its injection, while Kenichi suspected Danzo was preparing to target the Uchiha Clan.

• Kenichi Amamiya and Orochimaru entered the capital and met a Root shinobi, who gave Orochimaru a Sealing Scroll from Danzo.

• After dismissing the Guardian Ninja and servants, the Daimyo began serious discussions with Orochimaru, who started explaining the serum’s possible side effects before injection.

Kenichi Amamiya encountered Asuma Sarutobi among the Guardian Ninja and learned that Asuma had left Konoha. As Orochimaru departed, Asuma fumbled and dropped a book Tsunade had left with him at Orochimaru’s feet.

• Kenichi Amamiya spotted Kazuma and the other Guardian Ninja outside after helping his teacher with a performance.

• Asuma recognized Orochimaru’s name and considered attacking Kenichi, but held back because he knew Orochimaru was too strong.
• Asuma remembered Tsunade’s gambling debts and searched for the book she had left as collateral.
• As Orochimaru came out, Asuma tried to hide the book, fumbled, and dropped it at Orochimaru’s feet.

At the Daimyo’s Estate, Asuma Sarutobi accidentally exposed Jiraiya’s book about Orochimaru to Orochimaru himself. Orochimaru learned that Tsunade was at the Golden Rose Casino and left with Kenichi Amamiya to confront her, while hinting that Jiraiya would be next.
