Arc 1Uka Awakens Wood Release
Uka Senju’s experiments with the Gene System gave him Wood Release, while Root’s surveillance of the Senju escalated into an attempt to abduct him. After Uka killed two Root operatives to protect himself and Senju Harumi, the clan concealed his ability and began investigating its origins.
- Uka Senju was detained after blasting a Sarutobi shinobi unconscious while fishing, but the Senju Second Elder secured his release and warned Hiruzen Sarutobi against interfering with the clan.
- Uka used the Gene System to create a Wood Release bloodline enhancement, then developed a wooden Battle Armor Technique and continued training at the Ninja Academy.
- Chiharu explained that the Relief Home generation opposed the Senju’s seclusion, and Uka realized the clan’s future no longer depended only on its elders.
- Shimura Danzō established Root, ordered it to monitor the Senju, and later learned that the clan had tightened security and recalled more than a hundred people.
- At school, Uka and his friends fought Sarutobi students, while their teacher announced an exam that offered rewards and privileges to top-ranking students.
- Danzō ordered Root operatives to bring Uka in quietly, but Uka refused their demand in an alley and sent Senju Harumi to get help.
- Uka killed two Root operatives with Wood Release spikes, and Senju patrol members arrived to treat Harumi and recover the bodies.
- Senju Toka called off the clan’s planned attack and ordered Uka’s Wood Release kept secret, while Mito Uzumaki and the elders began discussing how to investigate his awakening.
