Arc 9Palm Thunder and Yahiko’s Mission
Shinsei helped repel Obito, returned to Konoha, and developed Palm Thunder while training others and protecting Gaara. The arc ended with Shinsei and Jiraiya taking Yahiko toward the Land of Rain, unaware of who was watching their departure.
- Shinsei and the allied fighters battled Obito, discovered how his space-time ability worked, and watched him escape after he returned with his Rinnegan and Sharingan intact.
- Shinsei accompanied Ōnoki to investigate the missing Four-Tails and Five-Tails Jinchūriki, then learned Akatsuki demanded his death in exchange for their lives.
- Shinsei returned to Konoha with Tsunade, Sasuke, and Hinata, and later discussed Obito, Gaara, and the threat of Akatsuki with Tsunade.
- Shinsei trained Tsunade and Sasuke in Sage Mode, helping Tsunade master senjutsu chakra while Sasuke’s memories triggered his Susanoo.
- Mito Uzumaki reinforced Gaara’s seal, comforted Kushina about the Nine-Tails, and welcomed Kakashi as he reunited with Hatake Sakumo.
- Shinsei and Tsunade developed Palm Thunder, a sealing technique that compressed natural water into explosive spheres, and Tsunade ordered Shinsei to make fifty for the Hokage.
- Tsunade sent Shinsei and Jiraiya to the Land of Rain with Yahiko, who reflected that peace required changing people’s thinking, while a man reported their departure to a masked figure.
