Ch. 1619Tsunade, You Wouldn't Want...
Madara Uchiha's reappearance shook the Allied Forces, while Sasuke and Kakashi continued fighting Obito. With Mizuki Ember facing Madara, Nagato, and the Ten-Tails, Orochimaru proposed using the Impure World Reincarnation Jutsu to summon Hashirama Senju, leaving Tsunade to confront the idea of her grandfather's soul being used in battle.
- The Konoha ninjas recognized the armored man as Madara Uchiha and began questioning Obito's identity, weakening the Allied Forces' morale.
- Sasuke grew enraged at Obito, attacked him with Susanoo, and ignored Kakashi's warning while Obito taunted him.
- Tsunade and Jiraiya worried that Mizuki Ember could not defeat Nagato, the Ten-Tails, and Madara Uchiha, but Orochimaru said they could not safely join that battle.
- Orochimaru proposed using the Impure World Reincarnation Jutsu to summon Hashirama Senju as a rival for Madara Uchiha.
- Tsunade objected that reanimating her grandfather would desecrate the dead, and Orochimaru urged her to consider the Ninja World's survival.
