Ch. 621A Reason He Couldn't Refuse
Shamu visited Kimimaro, promised to help him evolve his eyes with Shamu’s genes, and said he would soon leave on a journey. At Orochimaru’s lab, the group resurrected Madara and asked him to guard the Shinobi World; when Madara refused, Shamu offered to revive Izuna.
- Shamu found Kimimaro training in the Rainbow Crystal Barrier and agreed to have Orochimaru test whether Shamu’s eye genes and ocular power could help Kimimaro’s eyes evolve.
- Shamu told Kimimaro he would leave soon to seek a breakthrough, while Kimimaro and Haku would stay behind and continue training.
- Orochimaru used Impure World Reincarnation to bring Madara back, and Madara reacted with anger and surprise at seeing Hashirama, Shamu, and Nagato.
- Hashirama explained that two and a half years had passed, peace had come to the Shinobi World, and Shamu wanted Madara to serve as its guardian while he was away.
- Madara refused the role, and Hashirama’s appeal to fight together failed to overcome Madara’s reluctance over Tobirama; Shamu then offered to revive Izuna.
