Namikawa Yū built a prosperous realm with Kaguya while secretly harnessing chakra to cultivate another Chakra Fruit, as the God Tree’s growth threatened the world. Hagoromo and Hamura returned with their families, and Namikawa Yū granted Indra and Asura islands to rule.
After leaving the panel world, Namikawa Yū returned to Konoha, gained a modified Karma, and became a Medical Ninja as the Third Shinobi World War escalated. He survived a dangerous mission, recruited Shanming Changjin, and became Namikaze Minato’s student, ending with a request to learn the Flying Thunder God Technique.
Namikawa Yū secured the Uchiha Clan’s support for Namikaze Minato, then began a new life as an Uchiha and rose through Konoha’s medical ranks. After Senju Tobirama and Hiruzen Sarutobi disappeared, Yū entered the contest for Hokage, leaving Shimura Danzō scrambling to counter his growing support.
Namikawa Yū became Uchiha Clan Head and Third Hokage, reorganized Konoha's education and finances, and fought the Kinkaku Brothers alongside the Third Raikage. He developed a living vessel for part of the Nine-Tails, then turned his attention to Konoha's students as Tsunade and Orochimaru excelled in their examinations.
Namikawa Yū gained Wood Release and Nine-Tails power before defending the Land of Whirlpools from Kumogakure and negotiating the Uzumaki Clan’s relocation to Konoha. As the migrants settled and Madara took an interest in Yū, the Hyuga Clan confronted how much it had fallen behind Konoha’s changes.
Namikawa Yū transformed Konoha into the center of a united Ninja Federation while strengthening his powers and deceiving Black Zetsu. The Federation brought peace and prosperity, but Uchiha Madara recommitted to the Eye of the Moon Plan, and Yū awakened his Mangekyō Sharingan in preparation for their coming clash.
Namikawa Yū stopped Uchiha Madara’s attempt to gather the Tailed Beasts, then left the Ninja World after arranging for the Federation to continue without him. Back in Konoha, he helped expose Orochimaru’s experiments and weaken Shimura Danzō’s control of Root.
