Chapter Summaries

Chisen taught Guy controlled breathing during rehabilitation, while Neji and Tenten encountered an elderly woman waiting beneath a persimmon tree for her absent grandson. The recovering team took on small errands around Konoha, and Chisen began treating Mrs. Yamaguchi’s mold-stricken clivia, leaving it replanted in fresh soil.

• Chisen showed Guy how to control his breathing with a trainer and set his daily rehabilitation routine.
• Neji and Tenten met an elderly woman waiting beneath a persimmon tree for her grandson, who had not returned from the Land of Iron in two years.
• Tenten ate an unripe persimmon and told the elderly woman it was sweet.
• Chisen, Guy, Neji, and Tenten began handling small errands in Konoha while recovering from their injuries and restrictions.
• Chisen diagnosed Mrs. Yamaguchi’s clivia with root rot from overwatering, removed its rotten roots, disinfected it, and replanted it in fresh soil.

Chisen replaced Guy’s dead pothos and agreed to return to Pheasant Feather Valley with him in eight weeks to recover its research records. Tsunade then summoned Team Guy after Kirigakure reported an unknown tailed-beast-level chakra eruption on an island, where a dying scout sent the word “Vessel.”

• Chisen gave Guy a healthy pothos and explained how to care for it, then told him he wanted to retrieve the records beneath Pheasant Feather Valley.
• Chisen and Guy agreed to return to Pheasant Feather Valley in eight weeks, after their injuries and chakra had recovered.
• Tsunade summoned Guy, Tenten, Neji, and Chisen to report that Kirigakure had detected chakra eruptions on an unnamed island in the Land of Water.
• Tsunade explained that the chakra matched none of the nine tailed beasts, and Neji suggested the God Tree could produce a similar level of chakra.
• Tsunade revealed that a Kirigakure reconnaissance squad had been wiped out in an underground cavern, and its captain’s final transmitted word was “Vessel.”

Chisen deduced that Kabuto had created a human vessel infused with God Tree cells and tailed-beast-level chakra on the Nameless Island. Though Team Guy was badly injured, Chisen proposed using fragments of his shattered blade to build a resonance array against the vessel, and began assigning the fragments to their fighting styles.

• Chisen explained that Kabuto could turn almost anyone into a vessel by using God Tree cells and White Zetsu-derived immunosuppressive factors.
• Guy and Neji concluded that the vessel could surpass the White Zetsu Army and might absorb chakra during combat, making a prolonged fight dangerous.
• Tsunade revealed that Kirigakure had requested Team Guy’s help investigating the Nameless Island in exchange for its reconnaissance data.
• Chisen judged that Team Guy had at most a thirty percent chance of winning a conventional assault because of their injuries and his inability to use chakra.
• Chisen proposed using resonance tuned to God Tree chakra’s 7.3-hertz frequency and revealed fragments of his shattered blade for a resonance array.
• Chisen suggested embedding the fragments in Tenten’s weapons and having Neji carry their vibrations through the Eight Trigrams Vacuum Palm.

Chisen presented a mechanical resonance plan for defeating the suspected God Tree jinchuriki, and Tsunade authorized Team Guy’s S-rank mission to the island. As the team prepared to leave, Tenten and Chisen concluded that Pheasant Feather Valley may have been only Kabuto’s outpost and questioned what formed the island vessel’s artificial chakra core.

• Chisen explained how Guy, Neji, and Tenten could use synchronized 7.3-hertz attacks to create resonance, and Tsunade questioned the plan’s assumptions and risks.
• Chisen defended his readiness to command from the battlefield, while Guy requested a neurological assessment; Tsunade authorized the S-rank mission for departure in four days and warned them not to pursue Kabuto or let Chisen use another neural stimulant.
• In the corridor, Guy questioned Chisen about helping an unknown genin, and Chisen explained that he had corrected the genin’s inaccurate shuriken throws because they could endanger him on a mission.
• Tenten suspected that Pheasant Feather Valley had been a diversion and that Kabuto’s real Vessel Plan was in the Land of Water; Chisen and Guy agreed that the valley may have been only an outpost.
• Chisen said the team needed to discover what Kabuto used instead of a tailed beast to create the island vessel’s artificial chakra core and identify its weaknesses.

Chisen and Neji uncovered how God Tree cells caused an abnormal chakra waveform in a fisherman from Boqie Island, and developed a plan to trigger the island vessel’s immune rejection through resonance. Chisen proposed stopping at Boqie Island to find the fisherman and test his blood before confronting the vessel, while Team Guy began training with the resonance array.

• Chisen led Neji and Tenten to Konoha Hospital’s underground archive to examine records of an abnormal chakra waveform measured in a fisherman three years earlier.
• Neji and Chisen found that the waveform’s secondary oscillations measured 7.31 hertz, nearly matching the God Tree Main Root’s 7.3-hertz frequency.
• Chisen and Neji traced the fisherman’s home to Boqie Island, twelve kilometers from Nameless Island, and concluded that exposure to God Tree cells had caused a temporary transplant rejection.
• Chisen explained that resonance could disrupt the vessel’s chakra pathways and restart its dormant immune system, causing the body to reject the God Tree cells.
• Chisen proposed stopping at Boqie Island to locate the fisherman and test his blood and chakra pathways before going to Nameless Island.
• At Konoha’s Third Training Ground, Chisen gave Guy, Tenten, and Neji earplugs before they began joint training with the resonance array.

Chisen guided Guy, Neji, and Tenten through joint training to synchronize three different attacks near the God Tree’s 7.3-hertz frequency. After recalibrating their rhythms, they achieved three brief resonance locks, leaving Chisen convinced that sustained resonance could breach a vessel’s chakra pathways.

• Chisen explained the training method and used a string-based resonance detector as Guy, Neji, and Tenten prepared their different vibration sources.
• Guy’s punches, Neji’s pulsed Air Palm, and Tenten’s fragment-bearing kunai converged on a striking post, but phase drift kept their resonance unstable.
• Chisen identified timing errors in each trainee’s rhythm and recalculated a plan to compensate for Guy’s breathing, Tenten’s kunai deceleration, and Neji’s chakra lag.
• The trio followed Chisen’s revised plan, and their second training round produced three resonance locks, the longest lasting 2.8 seconds.
• Chisen said that sustained resonance of that length could breach a vessel’s chakra pathways and trigger a rejection reaction.

Team Guy traveled to Boqie Island to find Akamatsu Kinpei, a fisherman whose past exposure to the God Tree’s chakra might explain unusual activity in the eastern waters. Kinpei described a rhythmic humming inside his bones, and Neji activated his Byakugan to inspect his chakra pathways.

• Guy and Chisen discussed how Guy could maintain steady punching frequency through pain, and Chisen prepared waterproof cards with the team’s resonance parameters and contingency plans.
• Team Guy left Konoha and traveled by three boats to Boqie Island, where retired Kirigakure Anbu Hiruma identified Akamatsu Kinpei as their contact.
• Chisen explained that Kinpei’s reported seabed sound might have been caused by 7.3-hertz infrasound transmitted through seawater.
• Chisen asked Kinpei to provide blood and undergo tests, and Kinpei said a steady humming sound still seemed to come from inside his bones.
• Neji activated his Byakugan to examine Kinpei’s chakra pathway system.

Chisen explained that Akamatsu Kinpei’s bone hum came from a harmless God Tree cell crystal and collected his blood to study its antibodies. At Nameless Island, the team compared his antibody response with the chakra eruptions from the cave and concluded Kabuto’s vessel depended on frequent immunosuppressive factors, possibly supplied by an implanted gland.

• Neji identified scar tissue in Akamatsu Kinpei’s chakra pathways, and Chisen determined that a marrow crystal caused the steady hum Kinpei had felt for three years.
• Chisen told Akamatsu Kinpei the crystal could not be safely removed, drew his blood, and learned that Kinpei had encountered a white glow in the sea near Nameless Island three years earlier.
• The Kirigakure Anbu boat brought Chisen, Guy, Tenten, and Neji to Nameless Island, where Tide warned them of recurring chakra vibrations and a dangerous tide-bound cave entrance.
• Chisen compared Kinpei’s antibody waveform with the island’s chakra eruptions and found that Kabuto’s modified God Tree cell strain differed from the tissue at Pheasant Feather Valley.
• Chisen estimated that the vessel needed immunosuppressive factors replenished every thirty-six to forty-eight hours, and Neji suggested an implanted gland that produced them could be its weak point.

Chisen and Team Guy entered the cavern to destroy a gland sustaining the humanoid vessel, while Neji discovered backup glands that could allow Kabuto to replace it. The chapter ended with the possibility that another vessel was already active at the Experiment Site.

• Chisen devised a plan to use a narrow stinger to destroy the vessel’s chest gland after Tenten’s Resonance Array broke down its chakra defenses.
• Tide briefed Team Guy on the cavern and warned them about an unexplained white light in the northeast passage.
• Team Guy entered the cavern at low tide and followed chakra conduits toward the underground chamber.
• Neji confirmed the vessel’s gland and found six backup cultivation tanks in the northeast passage, one of which was empty.
• Neji warned that the missing gland might already have been implanted in another vessel.

Team Guy attacked the awakened vessel in the cavern with a Resonance Array while Neji destroyed its culture tanks. The vessel’s gland weakened and its rejection response began, but the chapter ended with Neji returning after smashing five tanks and the resonance cage still holding.

• Guy ordered Tenten and Neji to maintain a Resonance Array, assigned himself to keep the vessel occupied, and sent Neji to destroy the culture tanks while Chisen watched for an opening.
• Tenten launched vibrating kunai into the cavern walls as Neji used Eight Trigrams Vacuum Palm and Guy’s punches to disrupt the vessel’s chakra field.
• Neji smashed the first culture tank, and Chisen determined that the tanks’ glands were linked to the vessel’s chest gland through chakra.
• The vessel charged toward the side passage, but Guy intercepted it and drove it into the cavern wall while Tenten strengthened the array with five more kunai.
• Neji smashed four more tanks, causing the vessel’s gland to slow and weaken as its rejection response began; he then returned from the side passage while Tenten maintained the resonance cage.

Guy’s team confirmed that the vessel died from an immune rejection that destroyed the God Tree cells, then left Nameless Island after eliminating the remaining cultivation tanks. Chisen’s waveform analysis revealed that the vessel and the God Tree Main Root shared a fundamental frequency of 7.3 hertz, but the vessel’s unstable secondary oscillations matched Akamatsu Kinpei’s antibody reaction frequencies.

• Chisen confirmed that the vessel had died after its immune system eliminated the God Tree cells, and Guy said they had only reactivated its body’s defenses.
• Guy reported to Tide that the vessel and all cultivation tanks had been destroyed, while Kabuto had not been found on the island.
• Guy reviewed Chisen’s neurological assessment and learned that Chisen experienced an occasional right-index-finger tremor but considered himself fit for command duties.
• Tenten and Neji watched bioluminescent water trail behind the speedboat, and Neji told her that her chakra pathway diagram was prettier than his.
• Chisen compared the vessel’s residual chakra waveform with the God Tree Main Root’s waveform and found that both had a 7.3-hertz fundamental frequency, while the vessel had irregular secondary oscillations matching Akamatsu Kinpei’s antibody reactions.

Chisen deduced that Kabuto’s decoy experiments had prepared the way for a hidden facility to mass-produce tailed-beast-level vessels. After returning to Konoha, the team received medical evaluations, and Chisen proposed using Akamatsu Kinpei’s unusual antibodies to trigger rejection in Kabuto’s vessels, though the available blood could support only six to eight experiments.

• Chisen explained that Pheasant Feather Valley and Nameless Island were decoys, and that Kabuto’s real goal was to assemble a facility for large-scale vessel production.
• Shizune met Team Guy at Konoha’s docks and took Chisen directly to the hospital, where Tsunade examined the returning team.
• Tsunade ordered Guy to avoid combat for twelve weeks, prescribed four weeks without intense chakra training for Neji, and gave Tenten treatment for swelling around her old eye injury.
• Chisen found that Akamatsu Kinpei’s blood contained antibodies that reacted rapidly to god tree cells because his immune system had retained a three-year memory of them.
• Chisen proposed turning Kinpei’s antibodies into an awakening agent that could restart rejection in Kabuto’s vessels, but said the available blood would cover only six to eight experiments.

Chisen secured Tsunade’s approval to use Konoha’s gene synthesizers and explained why the Awakening Agent had to be completed before Kabuto built another vessel. After Guy learned Chisen’s backup plan for destroying a vessel’s gland, he committed to recovering and helping him carry it out if needed.

• Chisen told Tsunade that cloning the antibody would require Orochimaru’s technical help and gene synthesizers, and Tsunade granted him access while warning him to account for his hand tremors.
• Chisen said he had arranged for Kirigakure to protect Akamatsu Kinpei under a joint agreement to share biological-preparation technology with Konoha.
• Guy visited Chisen’s lab and asked whether his plan to insert the Stinger into a vessel’s gland had been genuine.
• Chisen showed Guy his calculated anatomical plan for destroying the gland if the vessel’s culture tanks were no longer connected to it.
• Guy said he would ask Tsunade for a suitable partner after his ribs healed, and Chisen told him they had limited time before Kabuto could rebuild.

Chisen completed the first batch of Awakening Agent and received Orochimaru’s experimental notes on Kabuto’s immunosuppressive factor. The notes revealed a temperature-sensitive weakness in the next-generation vessel’s immunosuppression, leaving Chisen with a new experimental route to pursue.

• Chisen decoded Akamatsu Kinpei’s antibody gene and spent six weeks overcoming cloning and protein-folding problems to produce twenty ampoules of Awakening Agent stock solution.
• After his ribs healed enough for light training, Guy returned to the training grounds while Chisen watched him practice palm strikes.
• Mitsuki conveyed Orochimaru’s advice to shorten a refolding stage, and Chisen changed the synthesizer’s holding time from thirty minutes to five.
• Mitsuki offered Orochimaru’s notes on the immunosuppressive factor in exchange for keeping them out of the public database and letting Konoha hear Orochimaru’s opinion if a future technology conflict arose.
• Chisen read the notes and learned that Kabuto’s next-generation immunosuppressive factor lost its activity above forty degrees Celsius, then left to develop a way to use that weakness.

Chisen completed the Type A Awakening Agent and planned a raid on Kabuto’s Crescent Archipelago facility, where three vessels were amplifying chakra to form a powerful core subject. Team Guy reached the facility and found the subject nearing completion, with only fifteen to twenty minutes to stop it.

• Chisen completed the Type A Awakening Agent and recorded that it required testing in actual combat.
• Tsunade assigned Team Guy to raid Kabuto’s experimental facility in the Crescent Archipelago, destroy the Core Experimental Subject, and capture Kabuto if possible.
• Chisen proposed using sixteen naturally coupled fragments to create a resonance pulse strong enough to overwhelm the three vessels’ combined chakra field.
• Chisen told Guy he could walk to the center of the formation and place the Mother Fragment there, and Guy accepted his assurance.
• Team Guy and Kirigakure’s Anbu landed on the island, and Team Guy advanced toward the facility while the Anbu cleared its outer defenses.
• Neji identified the unfinished Core Experimental Subject inside the vessels’ chakra formation and estimated it would take fifteen to twenty minutes to complete; Guy chose to break through directly.

Guy, Tenten, Neji, and Chisen destroyed Kabuto’s core vessel in the Crescent Archipelago by synchronizing the resonance fragments, which also exhausted the fragments’ power. Kabuto escaped before they reached his facility, but left his equipment and records behind, giving Chisen a chance to learn about his next plans.

• Tenten, Neji, and Chisen coordinated attacks on the three outer vessels, then used four resonance positions to disrupt the chakra circuit linking them.
• Guy broke through the eastern defense as all sixteen fragments synchronized, allowing Chisen to place the parent fragment beneath the core test subject.
• Chisen’s directional resonance wave shattered the cultivation sphere and destroyed the unfinished, inactive core vessel, while the outer vessels succumbed to rejection reactions.
• Neji confirmed that Kabuto had escaped, though his specimens, equipment, and experimental records remained in the facility.
• Guy, Tenten, and Chisen found that the resonance had exhausted their fragments, and Chisen concluded that the surviving records might reveal Kabuto’s next plans.

Chisen discovered that Kabuto planned to create self-sustaining Immune-Integrated Vessels, narrowing the team's chance to stop him. On the way north, Guy's team encountered a gigantic unknown creature that attacked with chakra jets, and they prepared a coordinated strike on its dome.

• Chisen found Kabuto's notes describing plans to integrate immunosuppressive genes into vessels and warned that the team needed to act before mass production.
• Guy and the others continued north by speedboat, but chakra-contaminated seawater clogged the engine and an enormous shadow rose beneath them.
• The creature surfaced, and its chakra jets forced Guy, Neji, Tenten, Chisen, and the Kirigakure Anbu to dodge across the sea.
• Neji used his Byakugan to identify the creature's high-pressure chakra sac and the center of its dome as its weak point.
• Guy asked Neji to launch him ten meters upward with three consecutive Vacuum Palms so he could punch through the dome.

Guy, Tenten, Neji, and their companions destroyed a massive sea monster that had attacked them, then returned to the Land of Water’s main island. Chisen suspected the creature was connected to research involving God Tree cells, while he continued to hold back from using chakra.

• Tenten used her chakra-thread guidance network to send an explosive iron ball into the monster’s dome, opening a gap in its defenses.
• Neji propelled Guy upward with three Vacuum Palms, and Guy ruptured the monster’s central conduit with a punch, causing its saclike organ to burst and the creature to sink.
• Chisen concluded the creature had been designed as a disposable sea weapon and suspected its technology came from research connected to Orochimaru’s notes and the God Tree project.
• Tide inflated the backup boats, and the group rowed to the Land of Water’s main island before nightfall.
• Chisen examined the stone-like parent fragment and removed his waterlogged knee brace while the group traveled, without attempting to mold chakra.
• Tide led the group off the docks after arriving, where only two night-duty chunin were waiting.

In Conference Room Three, Chisen and the others reasoned that Kabuto had prepared disposable underwater ambush weapons along the routes from the Crescent Archipelago and had previously operated in the Land of Rivers. The chapter ended as Chisen identified the northern mountains’ underground rivers, limestone caves, and disputed jurisdiction as ideal conditions for Kabuto’s laboratory.

• Tide treated Chisen’s strained knee while Neji and Tenten tended to their injuries and equipment.
• Chisen concluded Kabuto had placed temporary biomechanical weapons along all three northern sea routes, and Tide agreed to close the other routes for three days under a tsunami warning.
• Guy brought intelligence reports describing suspicious activity at three sites in the northern Land of Rivers between April and July.
• Chisen linked the Land of Rivers activity to Kabuto’s later work in the Crescent Archipelago, noting that the earlier operation had ended two weeks before the facility was attacked.
• Tenten described the region’s underground river system, and Chisen explained how its water, caves, and ambiguous jurisdiction made it a suitable place for Kabuto’s experiments.

Chisen and the others traced Kabuto’s Immune-Integrated Vessel research from the Land of Rivers to Orochimaru’s underground facilities in the Land of Rice Fields. After learning that Kabuto had completed at least seven batches of cell-culture experiments and may be assembling a vessel there, they calculated how quickly they could reach the border.

• Guy presented a report showing that Kabuto had taken over a workshop at Tiantang Pharmaceutical Factory in the Land of Rivers and converted it into a cell-culture laboratory.
• Chisen and Guy concluded that Kabuto had begun immune-integration research months earlier and that his equipment had been moved out of the Land of Rivers.
• Neji and Tenten identified Dark Mouth, where an underground river emerged, as a route into the Land of Rice Fields and Orochimaru’s abandoned underground facilities.
• A fax reported that Tiantang Pharmaceutical Factory’s Workshop No. 3 had burned after its equipment was removed, and a partially burned label revealed that Kabuto had completed at least seven immune-integration culture batches.
• Chisen concluded that Kabuto had moved cultured samples and equipment to the Land of Rice Fields, where an Immune-Integrated Vessel might be nearing final assembly.
• Neji estimated that the group could reach the Land of Rice Fields border in about three days if they left immediately.
