Arc 15Sage Mode and Salamander War
Akaseki and Orochimaru mastered Ryūchi Cave’s Sage Mode before leaving to strike the giant salamanders guarding Amegakure. Their assault drew Hanzō into battle, where Akaseki and Garaga confronted him as the snakes and salamanders fought around them.
- Akaseki transplanted Uchiha Nanfeng’s blind eye, visited Jiraiya’s group in the Land of Rain, and later returned to Konoha with Nonō, Orochimaru, and Tsunade.
- Akaseki helped push Konoha to train more battlefield medical ninja, while Orochimaru and the Uchiha pressured the Hyuga and Yamanaka clans to contribute.
- Akaseki and Tsunade rescued Dan Katō after Sunagakure’s ambush, but his injuries left him unable to return to battle.
- Akaseki and Orochimaru entered Ryūchi Cave, where Akaseki survived its final Sage Mode trial through an Immersion scenario and Orochimaru completed his transformation with the Heavenly Cloud Sword.
- The White Snake Sage made Akaseki a Ryūchi Cave elder and gave him a scale to summon giant snakes before new orders sent him and Orochimaru toward the Land of Wind.
- Akaseki reunited with Jiraiya and planned an assault on Amegakure’s giant salamanders, leaving Yahiko, Nagato, and Konan behind with supplies and instructions.
- Akaseki used the White Snake Sage’s Scale to unleash snakes on Amegakure, and the Great Salamander King summoned Hanzō back to the village.
- Garaga confronted Hanzō, who wounded him, while Akaseki struck Hanzō with Susanoo’s Thunderflame Greatsword and tried to draw his anger as the battle continued.
