Uchiha Yu taught Yuki about the Yuki Clan’s future and gave her a month of freedom to investigate Kirigakure, then explored the Naka River with Miwa Masayo under an unusually powerful full moon.

• Miwa Masayo developed a craving for Uchiha Yu’s blood under the brightest moonlight of the year, so he cut his wrist and let her drink a drop.
• The drop of blood filled Miwa Masayo’s rising vitality and ignited her bloodline.

Uchiha Yu supplied Natural Energy to help Miwa Masayo survive a dangerous bloodline breakthrough, which gave her a second tail and powerful Wind and Fire abilities. Her uncontrolled flames ignited the Naka River, and the chapter ended with Orochimaru identifying the phenomenon and the Third Hokage extinguishing it with Earth Style.

• Uchiha Yu fed Miwa Masayo Natural Energy and killed a White Zetsu spy that witnessed her breakthrough.

Miwa Masayo struggled to control her new tails and learned she might eventually grow nine, while Orochimaru told Hiruzen Sarutobi that Natural Energy had caused the Naka River fire. The Hokage faction discussed how to find the mysterious Natural Energy user and manage Orochimaru, leaving Hiruzen wary of his former student despite their apparent reconciliation.

• After Orochimaru left, Hiruzen Sarutobi told Mitokado Homura and Utatane Koharu that he still feared Orochimaru’s political influence and believed Konoha needed Orochimaru’s cooperation.

Uchiha Yu agreed to serve as Orochimaru’s bodyguard during a trip to the Land of Rain in exchange for access to Konoha’s barrier weaknesses and confidential mission forms. He trained the younger Uchiha before leaving and received a report on Uchiha Obito that described his poor judgment and credited Shinichi with keeping him safe.

• Orochimaru admitted he had deliberately reconciled with the Third Hokage as a political tactic, then asked Uchiha Yu to guard his special clone while he handled private business in the Land of Rain.

Uchiha Yu explained the Mangekyō Sharingan to Uchiha Bushi and revealed why he considered Uchiha Obito and Uchiha Shisui likely candidates to awaken it. By the end of Konoha’s forty-fourth year, Yu had begun treating disabled ninja for mission rewards while concealing that his limb-regeneration method used Wood Style.

• Yu told Bushi that Obito had exceptional Mangekyō potential, then used a genjutsu lesson to explain the Sharingan’s history, the Mangekyō’s powers and blindness drawback, and Madara’s Eternal Mangekyō.
• Bushi asked Yu to teach him the true cultivation method, and Yu agreed on the condition that he keep the teachings secret.

As they left the village to find her, Tobirama learned about Konoha’s compromised barrier and Shimura Danzō’s Root, and approved of Yu killing Danzō.

• Senju Tobirama recognized Uchiha Yu’s Wood Style crystal as similar to one that had once emerged from Hashirama’s body and agreed to study it.
• Uchiha Yu explained that Tsunade had left Konoha after her brother Nawaki and lover Dan Katō died under suspicious circumstances, enraging Senju Tobirama.

• Uchiha Yu and Senju Tobirama reached Tanzaku Town and learned that Tsunade had lost all her money gambling and was staying at an inn.

• Tsunade shattered the ground with a Chakra Enhanced Strength punch, but the genjutsu left her curled up and trembling.
• Uchiha Yu told Senju Tobirama that Tsunade’s hemophobia stemmed from Dan Katō’s death and that her psychological illness had no known treatment.

• Uchiha Yu suppressed Tsunade’s fear with genjutsu, and Tsunade woke briefly before falling asleep in Senju Tobirama’s arms.
• Uchiha Yu explained that he could make Tsunade perceive blood as fireworks and flowers, and Senju Tobirama approved the temporary treatment.
• Tsunade woke in Tanzaku Town, mistook Senju Tobirama for a dream, then recognized his Impure World Reincarnation and became wary of Uchiha Yu.
• Uchiha Yu cut his wrist to demonstrate the genjutsu, and Tsunade saw fireworks and flowers instead of blood, though she still cried and punched him through the floor.
• Senju Tobirama demanded an apology, and Tsunade apologized to Uchiha Yu after realizing she had attacked someone stronger who had tried to help her.
• Uchiha Yu repaired the damaged floor with growing branches, and Tsunade recognized his Wood Style.

• Senju Tobirama told Tsunade that her brother had asked whether she was doing well, and Tsunade claimed she was happier than ever despite her grief.
• Senju Tobirama gave Uchiha Yu a Wood Style Crystal, and the two returned to Konoha while Tsunade considered whether she might pursue the Hokage position.
• Days later, Senju Tobirama revealed that experiments with Wood Style Crystals had damaged his Edo Tensei body, and Uchiha Yu explained that he had eaten one.
• Senju Tobirama examined Uchiha Yu by having him consume a small amount of crystal and tracking the changes in his chakra over several days.
• Senju Tobirama concluded that Uchiha Yu’s body rivaled Senju Hashirama’s and Uchiha Madara’s, and predicted that Yu would surpass them.

Uchiha Yu learned that his chakra and Senju Hashirama’s chakra seemed to belong to themselves rather than a shared source, then prepared for a dangerous Foundation Establishment breakthrough on the winter solstice. Yuki arrived with the Yuki Clan’s surviving children in danger, and Yu decided he had to honor his promise to protect them.

• Senju Tobirama asked Uchiha Yu to protect Konoha, shared his research on Wood Style Crystal, and discovered that Yu’s chakra reacted like Senju Hashirama’s.
• Senju Tobirama’s Impure World body expired, and Uchiha Yu decided not to reincarnate him again before the winter-solstice breakthrough.
• Uchiha Yu spent the following days investigating the chakra-erasure process, then suspended his research on December 14 to prepare for the breakthrough alone.
• Yuki reported that Kirigakure had attacked the Yuki Clan and that she had led its women and children away, but four women exposed their hidden sanctuary and the survivors remained hunted.
• Yuki begged Uchiha Yu for help after Kirigakure used tools made from Yuki Clan bones to track the survivors, and Yu asked where she had hidden the children.

Uchiha Yu helped Yuki reunite with the surviving Yuki Clan children and learned that Karatachi Yagura was leading Kirigakure pursuers toward them. Recognizing Yagura as the start of his human tribulation, Yu sent the children toward a desert oasis and prepared to face the enemy under the identity Zhurong.

• Yuki told Uchiha Yu that she had led the Yuki Clan children across several countries to the Land of Wind using icebergs, while Kirigakure tracked them with a blood-tracing tool that required a Yuki Clan member's blood.
• Uchiha Yu used Flying Thunder God to reach the fishing village and reunited with more than a hundred surviving children, after Yuki revealed that only a fraction of the three hundred she had taken from Kirigakure remained.
• Yuki described her plan to move the children to a buried oasis in the Land of Wind, and Uchiha Yu sensed that Karatachi Yagura and the pursuers were approaching.
• Uchiha Yu recognized Karatachi Yagura as the source of a human tribulation and decided to confront him rather than avoid the conflict.
• Yuki sent the children toward the oasis with supplies and a route map, then returned to Uchiha Yu, who disguised himself as Zhurong, the Fire God.

Yuki froze the sea and stopped the Fourth Mizukage’s tsunami with a newly developed Sage Art, after which Uchiha Yu unleashed fire drawn from an undersea volcano against the Kirigakure forces. Karatachi Yagura survived the bombardment with his Water Mirror and sent replicas of Uchiha Yu and Yuki to attack, but both replicas quickly vanished.

• Yuki used Sage Art: Ice Style: Glacier to freeze the beach and sea, stopping Karatachi Yagura’s tsunami and scattering the Kirigakure ninja.
• Uchiha Yu praised Yuki’s technique and then summoned a sky full of fireballs by drawing natural energy from a nearby undersea volcano.
• Karatachi Yagura rallied the Kirigakure ninja and led them across the ice, but Uchiha Yu’s fireballs struck the field in a deafening barrage.
• Yuki realized the bombardment’s roar had drowned out all other sound, while Uchiha Yu wrote “Great sound is nearly silent” in the sand.
• Karatachi Yagura emerged unharmed behind his Water Mirror and used it to create water replicas of Uchiha Yu and Yuki, which soon disappeared.

Uchiha Yu and Yuki fought off Karatachi Yagura and the Kirigakure ninja, but Yu realized that using an undersea volcano’s natural energy had triggered an earth tribulation. As the volcano threatened the Capital of the River, Yu stayed behind to protect its civilians while Yuki went to find the Yuki Clan’s children.

• Yuki attacked Karatachi Yagura and drew him into Uchiha Yu’s fireball-covered battlefield, while Yu disguised himself among the Kirigakure ninja and provoked them into killing one another.
• Karatachi Yagura fled after most of his forces died, and Yu sensed that his human tribulation had passed.
• Yu and Yuki concluded that Karatachi Yagura had become stronger but acted mechanically when faced with unexpected decisions, while the Hozuki and Kaguya clans benefited from his campaign against the Yuki Clan.
• Yu realized that borrowing energy from an undersea volcano had triggered his earth tribulation and that the eruption could threaten the Capital of the River.
• Yu sent Yuki toward the Yuki Clan’s children and headed across the exploding ice field, gathering senjutsu chakra to confront the danger to the city.
