Arc 8The Masked Man and the Akatsuki
Zou Hyuga and Oto Uchiha survived Obito’s attack, and Oto awakened her Mangekyō Sharingan while Zou concealed Moryo’s influence. Zou then protected the Tailed Beast Merchant Association, clashed with Akatsuki members, trained Haku, and returned to Konoha, where he brought Oto to the Valley of the End to test an idea.
- Cat Granny revealed that Moryo’s evil chakra was inside Zou Hyuga, while Oto Uchiha and Zou grew distant on their return to the Shinobi Village.
- Obito abducted Zou and attacked Oto, but Shisui arrived to help her fight him, and Zou struck Obito from inside the Kamui Dimension.
- Moryo took control of Zou and tried to force Oto to surrender her body, but Oto awakened her Mangekyō Sharingan and defeated him.
- Zou and Oto concealed Moryo’s chakra and Oto’s Mangekyō from the village, then reported the Masked Man’s return to the Third Hokage.
- Zou visited Kisame’s mountain base, took Haku with him, and learned that Akatsuki members were hunting Taro Utada for a bounty.
- Zou fought Kakuzu and two Kirigakure missing-nin while Haku used Ice Release to protect Utada and the guards, then Zou forced the Akatsuki to pay four million ryō to leave.
- Zou experimented with natural chakra and Haku’s Ice Release, returned to Konoha, and told Oto about his encounter with Akatsuki.
- Zou suggested that Obito might be the Masked Man, then led Oto to the Valley of the End and took her hand so she could focus on what she felt.
