Ch. 267The Eternal Eye's Sudden Attack
Kōki transplanted Uchiha Seika’s Mangekyō Sharingan into Uchiha Ryuko and observed it develop into an Eternal Mangekyō Sharingan. Just as he prepared to remove the new eye, Ryuko attacked with its ocular power, but Kōki drained Ryuko’s chakra and stopped him.
- Kōki arrived after arranging for his Wood Release clone to manage the Kumogakure battlefield, and he and Aizen began the experiment on Uchiha Ryuko.
- Kōki explained his theory that the origins of related Mangekyō Sharingan would complement each other, then transplanted Uchiha Seika’s eyes into Ryuko, starting with one eye.
- Over the following days, Kōki observed Ryuko’s chakra growing and waited to learn more about the awakening process.
- On the fifth day, Ryuko’s transplanted eye became an Eternal Mangekyō Sharingan, then unleashed ocular power that struck Aizen and Jörmungandr before targeting Kōki.
- Kōki resisted the attempted control, recognized that Ryuko had broken through his seal, and used Wood Release to drain his chakra, causing the Eternal Eye to revert to an ordinary eye.
