Arc 2The Hundred-Clan Nation Rises
Uchiha Mu expanded his nation, drew the tailed beasts and Madara into his orbit, and built ties with the Uzumaki while challenging Konoha and the other villages. After a tense Five Kage Summit, he brought a small group of Uchiha civilians to his nation, while Black Zetsu prepared to exploit the future wars.
- Uchiha Mu defeated Matatabi, brought her to meet Chōmei, and persuaded her to stay in his village.
- Madara Uchiha reconsidered the Eye of the Moon Plan after Mu warned him about its risks and urged him to learn the tailed beasts’ history.
- Mu helped Uzumaki Shana and Uzumaki Men win support to reform their clan, then escorted Uzumaki clansmen home and formed a marriage alliance with Keiko Uzumaki.
- Mu monitored Black Zetsu, whose conversations with Madara deepened Madara’s doubts, while Mu’s nation grew through trade and welcomed children from other clans.
- Mu returned to Konoha, confronted Uchiha clansmen, taught shinobi medical ninjutsu and chakra transformation, and helped Hyuga Lingnai free Hyuga Rei from the Hyuga Clan Compound.
- At the Five Kage Summit, Mu secured a film-business agreement as Hashirama Senju distributed the tailed beasts and the villages signed a peace agreement.
- Mu invited Uchiha civilians to join his nation, and fewer than fifty left with him through his Flying Thunder God technique.
- Black Zetsu concluded that Madara doubted the Eye of the Moon Plan and planned to provoke wars after Hashirama died.
