Arc 8The Arsenal and Obito
Naruto reshaped the Land of Hot Water, expanded Konoha’s weapons program, and entered three years of seclusion as his allies took charge. After Sasuke defended the Second Arsenal from Deidara and a masked attacker, Naruto connected the man’s abilities to Kakashi’s Sharingan and concluded that he was Obito Uchiha.
- Naruto used Jingwan, Kana, Zabuza, and the Eye of Order to defeat the Noble Alliance, seize its supplies, and force the nobles to surrender their wealth and power.
- Naruto established reforms and a Schola Progenium in the Land of Hot Water, then defended the arrangement to the Fourth Raikage and sold Kumogakure Thunderclap bolters.
- Naruto delegated his authority to the Core Committee and began three years of seclusion, while Hinata joined Schola Progenium and Sasuke trained under Kakashi.
- Konoha’s weapons trade drew interest from Ōnoki and Gaara, while Deidara and Obito attacked the Second Arsenal and Sasuke defeated Deidara’s clay weapons.
- Obito used Kamui to save Deidara from his own C0 explosion, escaped Sasuke, and returned with Deidara to Amegakure.
- Sasuke told Kakashi that the masked man’s eye resembled Kakashi’s, leading Kakashi to suspect that Obito had survived.
- At the Lantern Festival, Sasuke reported the Arsenal attack to Naruto, who connected the masked man’s Kamui, the Nine-Tails Rebellion, and the paired Sharingan to identify him as Obito Uchiha.
