Ch. 821A Backup Plan
Senyo had Orochimaru replace Hanabi's stolen Byakugan with another pair and discussed the progress and risks of the Uchiha eye experiments. In the Kamui Dimension, Obito and Black Zetsu regrouped after Itachi nearly defeated them, while Black Zetsu prepared to take the Byakugan to the moon.
- Senyo brought Hanabi to Orochimaru, who replaced her injured eyes with Byakugan from the Hyuga Main Family and assured Senyo that his backup plan would remain undetected.
- Orochimaru told Senyo that Itachi's eye fusion was nearly complete and Fugaku's ocular power had recovered, but Senyo decided Sasuke's body could not yet withstand the Eternal Mangekyo Sharingan.
- Senyo left Orochimaru to care for Hanabi and warned him not to reveal anything if Hinata visited.
- Obito and Black Zetsu returned to the Kamui Dimension after Itachi's strength and taijutsu had nearly beaten them, and Black Zetsu identified the Eight Inner Gates as the likely source of Itachi's power.
- Black Zetsu stored the Byakugan in a container and planned to go to the moon, while Obito explained that Naruto was a powerful, perfect Nine-Tails Jinchuriki.
