Arc 1Yubi’s Rise in the War
Yubi proved himself as a battlefield medic and fighter while raiding Amegakure with Sasori and Arai, then used his inventions and hospital reforms to earn Sunagakure’s attention. The arc left the village investing in his medical knowledge as the war became a contest of endurance.
- Rasa sent Yubi, Sasori, and newly graduated Genin to a canyon outpost, where Yubi treated an infected wound and soon faced Amegakure attackers alongside Endo and Sasori.
- As Amegakure forces pushed into the canyon, Yubi treated the wounded, killed pursuing enemies, and tended Sasori after an Amegakure Jonin injured him.
- Granny Chiyo arrived with reinforcements, and the Third Kazekage later praised Yubi and Sasori for defending the rear before assigning them to Arai.
- Arai trained Yubi in combat and led him and Sasori on raids into the Land of Rain, where Yubi developed Blade Intent Manipulation and the team repeatedly struck Amegakure outposts.
- After Yubi demonstrated his original ninjutsu to Sunagakure’s leaders, the Third Kazekage ordered its details kept secret, while Yubi recognized that the village might try to use him as an asset.
- Chiyo asked Yubi to spend time with Sasori and offered to teach him medical ninjutsu or puppetry, while Yubi also resolved to save Sasori and Pakura from their fates.
- Yubi trained Sunagakure’s hospital staff and improved treatment for wounded shinobi, earning a reputation as a miracle doctor and gaining leverage to seek a position in the village.
- Chiyo arranged for Yubi’s medical knowledge to be taught at the Ninja Academy, and the Third Kazekage declared that the war would depend on which village endured longer.
