Arc 7Super Amazing City and the Sharingan
Ren built up the Uchiha through new training methods and launched Super Amazing City, while Obito sent rogue ninja to provoke him. The attack on Kakashi ended with Ren defeating Sasori’s Iron Sand assault and sealing Kakashi’s Sharingan against removal.
- Tsunade became the Fifth Hokage and announced that the Uchiha would fund Super Amazing City, with Mabui overseeing the project and impressing Konoha’s officials with her plans.
- Ren gathered the Uchiha at Naka Shrine, honored their fallen, and pledged to lead the clan toward dominance before introducing the Tiger-Leopard Thunderclap Body-Tempering Technique and the Great River Qi Refinement Method.
- Ren made the first three stages of the Great River Qi Refinement Method available to qualified Uchiha and used the Contract Ghost-Faced Yama Technique to seal practitioners against revealing it.
- Pain ordered the Akatsuki not to act against Ren, but Obito maneuvered Orochimaru, Kakuzu, and Sasori into attacking Konoha to make Ren use his Mangekyo repeatedly.
- Ren replaced the original Super Amazing City plan with a five-billion-ryo reinforced-concrete project, and Mabui organized construction as workers and merchants arrived in Konoha.
- Kakashi followed Orochimaru, Sasori, and Kakuzu through Konoha, then fought Sasori’s Third Kazekage Human Puppet and was poisoned by its Iron Sand.
- Ren arrived, took control of Sasori’s Iron Sand, and used the Super Electromagnetic Cannon to blast Sasori and destroy much of the puppet.
- Ren recognized Kakashi’s Sharingan as Obito’s eye and placed a Cursed Seal on Kakashi’s brow, suppressing the eye and causing it to destroy itself if anyone tried to remove it.
