Chapter Summaries

Uchiha Yu defeated a Root ambush through genjutsu, then exposed Shimura Danzō’s scheme and won public recognition, though not the rewards he expected. Afterward, he realized that his fixation on the spoils and his own plans had made him careless about concealing his abilities and accounting for the Hokage’s interests.

• Uchiha Yu used repeated Sharingan feints to lower the Root ninjas’ vigilance, then froze the survivors with a genjutsu and crushed their hearts.
• Uchiha Yu questioned the one Root ninja who showed no fear, discovered he had two hearts, and suspected Orochimaru had modified him.
• Uchiha Yu explained to Miwa Masayo that he would expose the forged mission order publicly, then burned much of the battlefield to conceal his techniques and investigations.
• After news of the ambush spread, Hiruzen Sarutobi removed Shimura Danzō as Hokage advisor and publicly commended Uchiha Yu, placing him on the next jōnin promotion list.
• Uchiha Yu complained that he received no mission bonus or vacation, then realized his greed and fixation on his spoils had caused him to overlook important risks.

Uchiha Yu purified Little C’s influence on his mental world, then took a patrol mission that let him escape the Byakugan surveillance around camp and relax on an island. Orochimaru nevertheless began investigating Yu, finding the corpses he had killed and examining them closely.

• Uchiha Yu used the dantian bell and natural energy to restore the heart forms after Little C’s corruption, then studied the mental monster and his own instincts while keeping up his daily life with Miwa Masayo.
• After the Third Hokage denied him his expected leave and rewards, Uchiha Yu persuaded a mission administrator to let him take a jonin-level patrol mission.
• Orochimaru reviewed the mission Uchiha Yu had accepted and quietly took note of him before leaving the mission center.
• Uchiha Yu used the Shadow Clone Technique to patrol the waters around Hot Spring Mountain Peninsula while he and Miwa Masayo rested on an uninhabited island.
• Orochimaru investigated Uchiha Yu’s past and began dissecting the corpses Yu had killed ten days earlier.

Orochimaru deduced that Uchiha Yu had killed the Root shinobi by using genjutsu to manipulate their nervous systems, and became fascinated by Yu as a potential rival. Meanwhile, Yu and Miwa Masayo watched firefly squid spawn on a deserted island until a tailed beast’s enormous tentacle appeared, forcing Yu to reconsider his supposed vacation.

• Orochimaru autopsied six Root shinobi, concluded that their own muscles had destroyed their hearts, and inferred that Uchiha Yu’s genjutsu had taken control of their neural networks.
• Orochimaru realized that the missing Root commander had likely been among the enemies Yu reported destroying with Fire Style, and decided to conceal the flaws in Yu’s report.
• Orochimaru compared Yu to Senju Tobirama and imagined that Yu might become his opponent after Orochimaru became the Fourth Hokage.
• Uchiha Yu felt his unreliable Precognition flare up, then stayed on a reef to savor the first violet qi while remembering the night’s feast with Miwa Masayo.
• Yu and Miwa Masayo watched firefly squid gather to spawn as swordfish entered the bay to prey on their eggs, then Yu raised their campfire above the water with Earth Style: Rock Pillar.
• A gigantic, hatred-filled tentacle rose from the sea, and Yu and Miwa Masayo recognized its chakra as that of a tailed beast.

Uchiha Yu and Miwa Masayo battled a gigantic, chakra-bearing octopus that had attacked the squid gathering, then marked it and let it escape so they could hunt it again later. The octopus fled into the sea, and Yu tracked it as it secretly turned northeast.

• A giant octopus attacked the gathered squid, but the males distracted its tentacles until the females finished spawning and the squid dispersed.
• Miwa Masayo wounded and severed one of the octopus's tentacles while Uchiha Yu used genjutsu and wind blades to leave it vulnerable.
• Miwa Masayo plunged into the octopus's body as Yu drove wind blades through its wounds, badly injuring the giant creature.
• Uchiha Yu marked the octopus, released his control over its main brain, and let fear drive it back into the sea.
• The octopus fled southeast before turning northeast, and Uchiha Yu sensed its direction as Miwa Masayo said they would return when they were hungry.

Uchiha Yu rested with Miwa Masayo on a beach, then discovered that the dawn’s purple qi and pearls from the octopus could aid his cultivation. After swallowing the pearls, he began a dangerous breakthrough into the fourth stage of Foundation Establishment.

• Miwa Masayo persuaded Uchiha Yu to stop working and watch the stars with her until sunrise, then fell asleep in his arms.
• Uchiha Yu sensed that his cultivation was ready to advance but trusted his intuition and postponed absorbing lightning-element natural energy.
• At sunrise, Uchiha Yu inhaled a wisp of purple qi and found it dispersing inside his dantian.
• Miwa Masayo gave Uchiha Yu two pearls she had dug from the octopus, and he swallowed them despite her protests.
• The pearls released pure lightning-element natural energy, triggering Uchiha Yu’s breakthrough while the surrounding supply seemed insufficient to restore the balance in his body.

Uchiha Yu absorbed lightning-nature natural energy and balanced the four natural energy attributes, but his breakthrough triggered a thunderstorm that battered him with natural lightning. The strikes ultimately tempered his body and forged a powerful Dao foundation, though he continued to suffer alternating pain and unbearable itching.

• Uchiha Yu absorbed the octopus pearls’ concentrated lightning-nature natural energy, drawing in enough natural lightning to balance all four natural energy attributes and begin forming Lightning Style chakra.
• Uchiha Yu realized his advancement had triggered a thunderstorm, protected Miwa Masayo from the static field, and fled with her as the storm followed him.
• Uchiha Yu sent Miwa Masayo away and tried to evade the lightning by sinking underground, but a bolt struck him and blasted him back to the surface.
• Uchiha Yu attempted Earth Style, Lightning Style, Water Style, and Wind Style defenses, but the storm overwhelmed them and scorched his internal organs.
• Uchiha Yu’s body began to itch unbearably, and he discovered that lightning strikes temporarily relieved the sensation, so he deliberately drew lightning down onto himself.
• The natural lightning tempered Uchiha Yu’s body, giving him extraordinary lightning resistance and forging a sturdy Dao foundation as he continued to endure the storm.

After surviving the thunderstorm, Uchiha Yu gained lightning powers, rapid healing, and a greatly extended lifespan, while Miwa Masayo discovered that even weak lightning was too painful for her. The pair rested on the beach after sharing a satisfying meal of octopus.

• Miwa Masayo reached the mountaintop and found Uchiha Yu unconscious, charred, and smoking after the thunderstorm’s final lightning barrage.
• Uchiha Yu awoke, apologized to Miwa Masayo for taking such a dangerous risk, and demonstrated that he could summon and absorb lightning without being harmed.
• Uchiha Yu explained that lightning had given him Thunder Arts, powerful self-healing, a lifespan of at least three hundred years, and an ageless appearance.
• Miwa Masayo asked Uchiha Yu to test her resistance with a weak bolt, but the lightning struck her tail and caused her so much pain that she abandoned the idea.
• Uchiha Yu recovered, and he and Miwa Masayo ate pan-fried octopus before resting together beneath the trees by the beach.

Uchiha Yu used a lucid dream to abandon the Five Elements framework and define a new system of Five Spirit Natural Energies, then spent a peaceful month secluded with Miwa Masayo. Meanwhile, Kirigakure prepared to attack the Land of Fire, and Uchiha Madara secretly advanced a plan to destroy the village and manipulate the Three-Tails before returning to his base.

• Uchiha Yu recognized that his unstable fourth heart form came from his attachment to the Five Elements theory, then used a lucid dream to rebuild his worldview and define the Five Spirit Natural Energies.
• Uchiha Yu woke from the dream, reflected on the Uchiha Clan’s vulnerability to emotional collapse, and invited Miwa Masayo to watch the sunrise and absorb its purple qi.
• Uchiha Yu and Miwa Masayo spent the next month training and cultivating in seclusion, while Miwa Masayo’s attempts to absorb moonlight essence failed.
• Kirigakure’s clans agreed to attack the Land of Fire, and the Third Mizukage proposed a new Bloody Mist policy to weaken the Kaguya, Hozuki, and Yuki clans.
• Uchiha Madara revealed that he intended to destroy Kirigakure, manipulate the Three-Tails, and prepare his successor before returning to his base.

Uchiha Madara hypnotized Isobu and the Third Mizukage, leaving Kirigakure poised to dispose of the Three-Tails and refuse a new jinchūriki. Uchiha Yu spotted Kirigakure's army mobilizing and warned Orochimaru, prompting Konoha to prepare for battle.

• Uchiha Madara used his Mangekyō Sharingan to control Isobu inside the imprisoned Three-Tails' jinchūriki, then confronted the Third Mizukage when he arrived with six Anbu.
• The Third Mizukage explained that the Mizukage had long practiced Water Style: Mirror of the Mind to break genjutsu, but Uchiha Madara overpowered him and left him with false memories and suggestions.
• Uchiha Madara left Kirigakure with Black Zetsu, saying the Third Mizukage would dispose of the jinchūriki and seal the Three-Tails without accepting a new host.
• Uchiha Yu and Miwa Masayo spotted Kirigakure mobilizing thousands of ninja, so Uchiha Yu abandoned their meal plans and sent a warning to Konoha.
• Orochimaru mobilized Konoha's ninja and organized preparations through direct subordinates and the mission center, while Uchiha Yu and Miwa Masayo withdrew to a remote corner of the camp.

Uchiha Yu met the Study Group genin in the Land of Hot Water and learned that the clan elders and Uchiha Fugaku had sent most of them away after many awakened their Sharingan. In Konoha, the Third Hokage and the other leaders discussed how to curb the Uchiha Clan’s growth, and Hiruzen proposed summoning two hundred and forty genin without specifying names.

• Uchiha Yu explained to Miwa Masayo why he refused to accept missions before reaching a clearer understanding of Orochimaru’s tactics.
• Uchiha Yu found Shigenobu, Ayumi, Hiroto, Kazushi, and the other Study Group genin at the supply tents and learned that one hundred of the group’s one hundred and forty-five members had been sent to the Land of Hot Water.
• Uchiha Yu recalled how the elders had admitted many upper-rank and direct-lineage children into the Study Group, leading to a surge in Sharingan awakenings and alarming the Third Hokage and Shimura Danzō.
• The Third Hokage rebuked Shimura Danzō for proposing to kill Uchiha Yu and ordered him to stop using cruel methods to train Root ninja.
• The Third Hokage proposed summoning two hundred and forty Uchiha genin without naming them, expecting Uchiha Fugaku to send the newly awakened genin who lacked family connections.

Uchiha Yu gathered the displaced Uchiha genin into the Tiger Roar Unit on the Land of Hot Water battlefield and gave them a shared purpose. As Kirigakure launched a major offensive, Orochimaru grew puzzled by the enemy fleet’s prolonged stay at an uninhabited island.

• Hiruzen Sarutobi devised a plan to transfer lower-ranking Uchiha who had awakened their Sharingan to the battlefield, and Uchiha Fugaku sent nearly all the old Study Group members away.
• Uchiha Yu learned that Uchiha Momoko and Uchiha Rinka had married and that Uchiha Kazuki had been sent to the Land of Rain.
• Uchiha Yu promised the gathered genin they would live, train, and fight together, then named their new group the Tiger Roar Unit.
• Uchiha Yu established the Tiger Roar Unit as an independent group in Konoha’s army camp and cautioned himself against expanding it too far.
• Konoha and Kumogakure coordinated their coastal defenses as Kirigakure’s fleet pressed forward, and Orochimaru questioned why it had stayed at an uninhabited island for more than two days.

Orochimaru and Nara Shikaku questioned why the Kirigakure fleet had lingered at an uninhabited island, while Kirigakure shinobi discovered the island’s devastation and feared its unknown cause. The fleet decided to leave after one more day, unaware that Uchiha Yu had caused the damage and was now cooking with vegetables from his island garden.

• Orochimaru questioned why the Kirigakure fleet had spent two days at an island with little to offer, and Nara Shikaku could not explain its delay.
• Hozuki Sakutsuki sent scouts to investigate the island, where Kaguya Ren and other shinobi discovered melted terrain and were shaken by evidence of a powerful attack.
• Ling analyzed the island’s droplet-shaped stones and speculated that an impossible cooling technique could freeze a person instantly, while Kaguya Ren insisted the attack had been caused by lightning.
• Hozuki Sakutsuki revealed that investigators had found a repaired house and a recently tended vegetable garden, suggesting someone had lived on the island after the devastation and left when the fleet arrived.
• Hozuki Sakutsuki recalled Uchiha Madara’s power, and Jonin Terumi proposed one more day of searches before the fleet sailed in a wide circle to hide its movements.
• Uchiha Yu cooked vegetables for the Tiger Unit and joked with Miwa Masayo and Uchiha Shigenobu about how he had built a house and planted a garden on the island.

Uchiha Yu fed Tiger Unit dried giant octopus meat and drove the genin through exhausting tactical drills as Kirigakure prepared to invade. After Kirigakure landed and Konoha faced a shortage of troops, Orochimaru ordered Tiger Unit to defend the Kubota Salient on the first line.

• Uchiha Yu served dried octopus meat to replenish Tiger Unit’s strength, and its chakra effects left the genin restless and unable to sleep.
• Uchiha Yu ordered Tiger Unit to drill the Four-Four Tactic through the night, while the captains explained that mastering it could improve their chances of surviving the war.
• Uchiha Yu’s Four-Four Tactic assigned each seventeen-person squad a captain and four teams, with leaders chosen for tactical judgment and compatibility rather than individual strength.
• Four days after Tiger Unit was formed, Kirigakure landed on the southern coast, forcing Konoha to mobilize while Orochimaru kept troops in reserve against Kumogakure.
• Orochimaru ordered Uchiha Yu and Tiger Unit transferred from the third defensive line to the Kubota Salient on the first line, despite Nara Shikaku’s warning about their inexperience.

Uchiha Yu led the Tiger Unit to defend the Kubota Salient and devised a mobile offensive plan against the larger Kirigakure force. After preparing the battlefield, he realized the hill could flood despite its drainage channels and began searching for a way to divert the water.

• Orochimaru ordered Uchiha Yu and the Tiger Unit to hold the Kubota Salient, and Yu accepted because abandoning his unit would condemn its 101 Uchiha genin.
• Uchiha Yu ordered drainage ditches dug and planned to use five squads to counterattack from the hill while his own squad tied down enemies inside Kubota Village.
• Uchiha Yu explained that defense could only support offense and urged the Tiger Unit to keep attacking even while Konoha was on the defensive.
• Uchiha Yu ordered the unit to prepare underground shelters and had Uchiha Tadamichi collect copper for whistles that would still work when soaked.
• Uchiha Yu realized the hill’s low elevation could let floodwater flow back despite the ditches, and he set out to find somewhere to divert it.

Uchiha Yu prepared a concealed, unstable sinkhole beneath Kubota Village and readied the Tiger Unit for an imminent Kirigakure attack. As Kirigakure’s leaders planned to assault the village, news that the Third Mizukage had been seriously injured threw their command into alarm.

• Uchiha Yu found a dry site with a vast underground cave, dug a shaft into it, and disguised its hollow top with stone pillars that would collapse as water accumulated.
• Uchiha Shigenobu reported that the captured Kirigakure scouts had all committed suicide, and Uchiha Yu urged the Tiger Unit to stay alert as the enemy approached.
• Uchiha Yu used genjutsu to strengthen Shigenobu’s resolve and spread a battle-ready mindset through the Tiger Unit, raising his confidence in victory to 85%.
• Hozuki Sakutsuki, Kaguya Ren, and Ling debated who should lead the attack on Kubota Village before settling their dispute and agreeing to proceed with their plans.
• A messenger reported that the Third Mizukage had been seriously injured, six Anbu had been killed, and the Mizukage Building had been damaged; Hozuki Sakutsuki ordered the report suppressed and increased the planned assault on Kubota Village to three hundred ninja.

Uchiha Yu’s Tiger Unit used whistle signals, diamond formations, and explosive weapons to slaughter Kirigakure forces around Kubota Village. After routing two groups and killing a Kirigakure jonin, Yu ordered a barrage of explosive short spears and buried tags against the remaining enemies in the village.

• Uchiha Yu kept the plan unchanged after discovering that more than three hundred Kirigakure ninja had arrived, and five platoons advanced into the mist.
• The Tiger Unit used brass whistles to coordinate attacks through the Hidden Mist Technique, killing more than sixty Kirigakure ninja in six minutes and driving the survivors into flight.
• Uchiha Shigenobu’s platoons replenished their weapons, then joined the pursuit and killed nearly all the fleeing Kirigakure ninja except one suspected jonin who escaped.
• Uchiha Yu led the Sixth Platoon into the northwest mist, where the Tiger Unit broke another Kirigakure force and Yu crippled and killed jonin Kamiya Kisho.
• Uchiha Yu ordered the Tiger Unit to attack the remaining Kirigakure ninja in Kubota Village with explosive short spears, triggering a chain of blasts that devastated buildings and terrified the enemy.

Uchiha Yu led the Tiger Unit in annihilating Kirigakure’s attack force at Kubota Village, then Kirigakure’s commanders argued over how to retake the key position. They chose the Kaguya Clan to lead the next attack, with Haiye stepping forward.

• Uchiha Yu and the Tiger Unit pursued the routed Kirigakure ninja, and Yu defeated jonin Dian with genjutsu and flaming fists before the unit wiped out the entire force.
• A surviving jonin reported that Kirigakure’s 300 elite troops had been annihilated by 102 Konoha ninja, who suffered no casualties.
• Hozuki Sakutsuki explained that losing Kubota would threaten Kirigakure’s supply route and offensive, but the clans refused to risk their forces against the defenders.
• Jonin Zao warned that an improvised army of a thousand would still fail to defeat the Konoha ninja, prompting the commanders to commit their three strongest forces.
• Kaguya Ren volunteered the Kaguya Clan for the attack and ordered Haiye to lead it.

Uchiha Yu replenished Tiger Unit’s supplies, steadied the 101 Uchiha genin after their first battle, and detected a White Zetsu nearby before sensing a large enemy force approaching. Kaguya Haiye led 513 ninja into a direct confrontation with Tiger Unit, and Uchiha Yu gave the order to attack.

• Kaguya Haiye agreed to mobilize at least 500 ninja and three jonin for the attack, then left in anger after Jonin Zao warned him about the force required.
• Uchiha Yu spent 40 million ryo replacing Tiger Unit’s weapons and Explosive Tags, while Miwa Masayo explained to Tanida Cat how Cat Castle profited from the purchases.
• Uchiha Yu helped Tiger Unit recover from its first battle, watched over the sleeping genin, and sensed a White Zetsu nearby without attempting to capture it.
• Uchiha Yu detected many approaching enemies, woke Tiger Unit, and found the genin calm and ready for battle after more than four hours of sleep.
• Kaguya Haiye led 513 ninja toward Kubota Village and ordered them to charge after sensing that an expert had detected him.
• Tiger Unit and the Kaguya force faced each other outside the village, and Uchiha Yu sounded the battle whistle and ordered a Fire Style attack.

Uchiha Yu led the Tiger Unit in a coordinated firebombardment that scattered and demoralized the Kaguya Clan force, then gathered his troops to counterattack. As Kaguya Haiye rallied his remaining fighters by revealing their Shikotsumyaku, Yu recognized the threat and led the Sharingan-wielding Uchiha into battle.

• Uchiha Yu coordinated the Tiger Unit’s fire attacks, killing and injuring Kaguya ninja while Kaguya Haiye struggled to detect the unseen danger.
• After six volleys, the Kaguya ninja broke orders and charged into Kubota Village, where Uchiha Yu withdrew his unit and left traps behind.
• Uchiha Yu praised the Tiger Unit’s discipline as the scattered Kaguya ninja emerged from the village demoralized and disorganized.
• Uchiha Yu ordered the Tiger Unit to advance against the Kaguya force, while Kaguya Haiye gathered just over a hundred ninja and prepared to fight.
• Kaguya Haiye and other Kaguya ninja revealed their Shikotsumyaku bone armor, stirring their fighters’ bloodlust as Uchiha Yu recognized them as elites.
• Uchiha Yu and the five squad leaders opened their Sharingan, rallied the Tiger Unit, and charged into battle.

Uchiha Yu led the Tiger Unit against Kaguya Haiye’s force and killed the Kaguya leader after a battle that lasted only six minutes and seventeen seconds. The Uchiha won Kubota Village, but suffered casualties, and Yu restricted newly awakened two-tomoe Sharingan users from leadership until their mental state could be evaluated.

• Kaguya Haiye charged Uchiha Yu, whose genjutsu misdirected Haiye’s attacks while Yu struck him with a series of punches.
• Haiye unleashed Dance of Thorns, trapping fighters from both sides in a growing bone cage, and Yu activated golden flames through his fist marks to kill Haiye and weaken the cage.
• Yu and the squad captains rescued fourteen Uchiha from the burning cage, but six had died; the Tiger Unit then defeated the remaining Kirigakure ninja in Kubota Village.
• Yu ordered the wounded, including Uchiha Bushi, sent to the Land of Fire for treatment and reported that the Tiger Unit had lost nine ninja while eliminating more than five hundred enemies.
• After several Uchiha awakened two-tomoe Sharingan in the battle, Yu barred them from leadership duties until they passed a strict mental evaluation.
