Chapter Summaries

Uchiha Yū led Hyuga Reiko and Nawaki on their first mission to eliminate a bandit stronghold, planning a nighttime assault after Reiko used her Byakugan to scout the fifty bandits. After the team killed the patrol and attacked a group sleeping in the eastern house, the noise alerted the rest of the stronghold, and Uchiha Yū used a Great Fireball Technique to set a house ablaze.

• Uchiha Yū assigned Reiko to scout the bandit stronghold, and she counted fifty people, including women and children.
• Uchiha Yū planned a nighttime attack, with Reiko and Nawaki handling the front while he carried out assassinations.
• Uchiha Yū, Reiko, and Nawaki killed the five-man patrol, though Nawaki's mistake nearly let one bandit signal for help.
• The team entered the eastern house and killed its sleeping occupants, but the commotion alerted the remaining bandits.
• Uchiha Yū struck the bandits in nearby houses with a Great Fireball Technique, setting one house ablaze.

Uchiha Yū, Nawaki, and Reiko burned down a bandit stronghold and killed everyone there to complete Orochimaru's mission, then faced his praise and criticism. On the return to the village, Orochimaru revealed that he had eliminated Hidden Cloud Village ninjas who had overlapped with their mission, and he planned to report the incident to the Hokage.

• Uchiha Yū and his teammates defeated the bandits and set the stronghold ablaze, then killed the bandits' families to complete Orochimaru's mission.
• Orochimaru congratulated the three on becoming qualified ninjas, criticized Nawaki and Reiko for hesitating and Uchiha Yū for failing to plan a more effective attack, and told them to wash and rest.
• After the team slept, Orochimaru led them back to the village while a group of pythons devoured several corpses from the Hidden Cloud Village.
• Orochimaru observed the three's chakra control on the journey and resolved to report the Hidden Cloud ninjas' presence to the Hokage.

Uchiha Yū and his teammates returned from their first C-rank mission as Konoha prepared for a possible war after discovering Cloud Shinobi reconnaissance and a leak about reserve warehouses. As Yū trained his radiation abilities, Kushina arrived with news of Tsunade’s medical training class.

• Kushina envied Uchiha Yū, Nawaki, and their teammate for completing a C-rank mission while she continued doing D-rank tasks.
• The team turned in the mission, received fifty thousand ryō, and split the remainder after giving half to Orochimaru.
• Orochimaru reported Cloud Shinobi traces and a map of Konoha’s reserve warehouses to the Third, who ordered Danzō to investigate a suspected traitor discreetly.

• Kushina told Uchiha Yū that Tsunade was opening a medical training class to assess shinobi for medical aptitude.

Tsunade launched a medical class to prepare Konoha for a possible war and introduced the Healing Technique to select students. Uchiha Yū wagered that he could learn it despite lacking Yang Release, then spent days experimenting and found that his version healed rabbits but produced unexpected problems.

• Tsunade explained that the medical class would select candidates who could master the Healing Technique and teach first aid to the rest.
• Uchiha Yū challenged Tsunade to a wager: if he learned the technique within seven days, she would teach him the Monstrous Strength Fist’s force application; if he failed, he would praise her strength to Orochimaru.
• Tsunade accepted the wager, while Orochimaru and Uchiha He doubted that Uchiha Yū could learn the technique.
• Uchiha Yū trained alone, using wounded rabbits to test the Healing Technique and gradually developing his own version.
• Uchiha Yū noticed that the rabbits healed visibly, but his technique differed from Tsunade’s recorded method and caused problems.

Uchiha Yū perfected a healing technique that could mend wounds, though his experiments also revealed its radioactive side effects. After demonstrating his success to Tsunade, he secured her promise to teach him the Monstrous Strength Fist, while she planned to persuade Orochimaru to have him study medical ninjutsu.

• Uchiha Yū discovered that his healing technique caused severe mutations and death when its radioactive effects were too strong, then spent several days adjusting its power.

Uchiha Yū practiced Tsunade’s Monstrous Strength Fist and joined Orochimaru, Nawaki, and Hyuga Reiko on a mission to escort Sand Village ninja from the Land of Rivers to Konoha. After a strenuous journey, the team rested for the night, with the prospect of encountering enemies still ahead.

• Uchiha Yū practiced the Monstrous Strength Fist, discovered its recoil could injure him, and declined Orochimaru’s offer to learn a snake-based ninjutsu.
• Orochimaru gathered Uchiha Yū, Nawaki, and Hyuga Reiko for a B-rank mission to escort Sand Village ninja from the Land of Rivers to Konoha.
• Orochimaru explained that the escort was intended to ensure Konoha could not be blamed if trouble arose in Sand Village, then led the team on a rapid journey to the Land of Rivers.

• Nawaki took guard duty while Uchiha Yū warned Hyuga Reiko not to hesitate if they encountered enemies.

• Orochimaru, Uchiha Yū, Nawaki, and Hyuga Reiko arrived in Hot Springs Village early and went to its mixed-gender hot spring.

• Musashi recognized Uchiha Yū and warned his teammates not to look into his eyes, but Kanno Koji dismissed the young Uchiha and attacked with Water Release.
• Uchiha Yū dropped his iron weights, evaded Koji’s Water Turbulence, and struck him with a powerful kick before countering his kunai with the Sharingan.
• Koji unleashed Water Release: Rushing Torrent, but Uchiha Yū split the current with the Monstrous Strength Fist and trapped him with Front Lotus.
• Uchiha Yū and Koji plunged into the hot spring, where Yū killed Koji; he then emerged and broke Musashi’s arm before killing him.
• Nawaki and Reiko stared in shock as Uchiha Yū asked why they were making such stunned faces.

Uchiha Yū, Nawaki, and Hyuga Reiko survived an ambush by Rain Village ninjas, then joined Orochimaru to meet Sand Village’s delegation led by Ebizo. As the group traveled toward Konoha, the Third Hokage received intelligence that the Land of Earth and the Land of Lightning might be preparing an alliance.

• Uchiha Yū’s display of strength left Hyuga Reiko and Nawaki discouraged, and he urged them to train harder.

• The Third Hokage told Mitokado Homura to have the ANBU watch developments, and Mitokado Homura reported signs that the Land of Earth and the Land of Lightning might form an alliance.

Danzō warned Konoha’s leaders that the Sand Village might turn against them, while Konoha secretly prepared to guard the border. After arriving in Konoha, Ebizo ordered Sand ninja to investigate promising young shinobi, even as Uchiha Yū, Hyuga Reiko, and Nawaki relaxed over an expensive barbecue meal.

• Danzō cautioned Konoha’s leaders that the Sand Village might side with their enemies, and they arranged for Sakumo Hatake to guard the border.
• Uchiha Yū, Hyuga Reiko, and Nawaki reached Konoha and discussed the Sand Village’s harsh conditions and dangerous ninja techniques over barbecue.
• Ebizo told the Sand ninja to investigate Konoha’s talented young shinobi, and he had already sent people to watch Uchiha Yū.
• Nawaki asked Uchiha Yū how he had grown so strong, and Uchiha Yū pretended that ordinary hard training was the secret.
• Nawaki agreed to pay for the meal, then stared in dismay at the bill as Reiko apologized for eating so much.

Uchiha Yū returned to the clan compound after dinner with Nawaki and learned that Sand Village ninjas had been following him. Fugaku protected him, advised him to train and awaken his Sharingan, and reported the intruders to the Hokage, where Danzō opposed an alliance.

• Hyuga Reiko left for the Hyuga compound with two branch-family ninjas, and Nawaki and Uchiha Yū parted ways after dinner.

Konoha prepared for possible war after Sand ninja investigated the village’s prodigies, and Hiruzen Sarutobi negotiated with Ebizo over an alliance and material aid. Ebizo rejected the clans’ marriage demands and revealed that Hanzō had met with the Third Kazekage, leaving Konoha to consider the threat from Rain Village.

Uchiha Yū watched Konoha and the Sand Village reach an agreement that gave the Sand Village territory in the Land of Rain, and he worried that the coming war would bring danger to the Uchiha Clan. As Uchiha Fugaku helped him obtain trained ninja crows and warned him to prepare for dangerous missions, Yū resolved to grow stronger while carefully developing the uranium inside his body.

• The Third Hokage agreed to the Sand Village's demand for territory in the Land of Rain and approved its requests for supplies.
• Uchiha Yū watched the Sand Village group leave Konoha, then went to the clan training grounds as Uchiha Fugaku taught younger shinobi.
• Fugaku told Yū that ninja crows needed specialized training and offered to help him obtain some; Shuiyun watched from afar and vowed revenge on Yū.

Uchiha Yū was forced to attend Tsunade’s medical ninjutsu classes, then became the subject of her investigation into his ability to handle extreme weights. After Tsunade found no unusual cause, Yū asked to use her laboratory to study the Healing Technique.

• Tsunade confronted Uchiha Yū for neglecting her research and made him join a group training session for medical ninjas.
• Uchiha Yū spent the day reviewing medical ninjutsu with Tsunade and the five trainees, then asked why he had to stay after the others left.
• Tsunade told Uchiha Yū to remove his upper-body clothes so she could examine him, suspecting his body could withstand heavy weights because of an unknown substance.
• Tsunade tested weighted equipment on Uchiha Yū and confirmed he could walk normally under weights that had overwhelmed Nawaki.
• Uchiha Yū told Tsunade about Might Duy, a taijutsu prodigy, and then asked to borrow her laboratory to test the Healing Technique on cells.
• Tsunade questioned why Uchiha Yū needed her laboratory when Orochimaru had experimental equipment of his own.

Uchiha Yū tested his unusual resistance to radiation and tried to develop the Healing Technique in Tsunade’s laboratory, but his experiments killed all her rabbits and cost him his mission earnings. Tsunade then assigned him to a medical mission escorting supplies to Sand Village, leaving him wary of the danger but interested in the reward.

• Uchiha Yū compared his blood and cells with Uchiha Clan samples, recorded that his cells absorbed radiation without mutating, and kept the findings secret.

• Uchiha Yū spotted Uchiha Shuiyun among the Konoha chunin, while Shuiyun watched him with hostility.

Uchiha Yū’s joint supply convoy left Konoha under the protection of Aburame Hanfeng and Sand Village ninja, while Uchiha Shuiyun secretly joined forces with Rain Village attackers. The Rain ninja ambushed the convoy in a mist-filled forest, and the two sides prepared to fight.

• Aburame Hanfeng assigned two tracking insects to Uchiha Yū and promised to protect him as the convoy departed Konoha.
