Arc 1Kōki’s First Battles
Kōki Itō entered the Ninja Academy, earned early graduation, and joined Team Uehara as war with Sunagakure approached. After growing into a capable teammate, he faced a deadly ambush that left Mei and Kazushi dead and brought him into combat with the remaining Sand ninja.
- Hiruzen Sarutobi rescued Kōki Itō from a laboratory, discovered his Wood Release, and arranged for him to live in Konoha while Danzō planned to claim him for Root.
- Kōki enrolled in the Ninja Academy, defeated Obito Uchiha in an assessment, and persuaded Hiruzen to let him take an early graduation exam, which he passed against Kakashi Hatake.
- Hiruzen assigned Kōki to Mamoru Uehara’s team, where Kōki passed Mamoru’s test and joined Yui Fujiwara and Masato Yoshino on a bandit-clearing mission that rescued captives and destroyed the stronghold.
- Kōki pursued medical training and sought instruction from Yūhi Shinku while Team Uehara completed an escort mission to the Land of Rice Fields.
- After three months of training, Kōki and Team Uehara went to support Anbu carrying intelligence from Sunagakure and were ambushed by Sand ninja.
- Kōki, Katsuto, and Yui worked together to kill Kira, but Mei died, and Kazushi was killed after Sunagakure poison paralyzed him.
- Kōki treated the injured Katsuto and Yui, then joined Mamoru’s fight and incapacitated Jun with the Heavenly Foot of Pain before telling Taku that Kira was dead.
