Arc 16Hikari’s Return
Akaseki helped expose the Third Mizukage’s scheme in the Land of Water, then escaped the Sand Ninja with Hikari, an ancient Uchiha sealed for over three hundred years. He brought Hikari to Konoha and reported the conflict to Hiruzen Sarutobi, while the village considered its next move.
- Akaseki and Jiraiya defeated Hanzō’s forces, and Akaseki sank Amegakure before returning to Konoha.
- Akaseki enrolled Guy alongside Kakashi and Obito, then remained in Konoha to develop Swamp Release as Orochimaru took command of the campaign against Sunagakure.
- Hiruzen Sarutobi sent Akaseki, Ranwu, and Shinnosuke to help Kirigakure capture the Six-Tails, but Akaseki discovered the Third Mizukage had allied with Sunagakure against the Karatachi family.
- Akaseki fought the Third Mizukage while Ranwu and Shinnosuke helped the Karatachi faction, then held off Luo Yan, Chiyo, and Ebizo as they pursued Yagura and him.
- Akaseki fled to the former Land of Whirlpools and freed Hikari, who used her Mangekyō Sharingan and black flames to kill Luo Yan while Akaseki killed Ebizo.
- Hikari told Akaseki she wanted to explore the modern shinobi world rather than join his plan for the Uchiha, then agreed to accompany him to Konoha.
- Akaseki brought Hikari to Konoha, where Grandma Chizuru registered her as an honorary granddaughter and Hiruzen Sarutobi approved her as a Konoha Ninja.
- Akaseki reported the Mizukage’s scheme and the Sand Ninja leaders’ deaths to Hiruzen Sarutobi, then arranged for Hikari to meet Ranwu, Shinnosuke, and Minato.
