Shisui Uchiha's remaining eye was entrusted to his best friend, Itachi Uchiha, and was subsequently implanted within a crow for safe-keeping.
The Fate of Shisui's Eye
Shisui Uchiha's Mangekyo Sharingan was a unique and powerful dojutsu, highly coveted for its ability to cast powerful genjutsu. Here's how his eye came to be in its current described state:
- Danzō Shimura's Pursuit: Fearing that Danzō Shimura, a high-ranking Konoha elder, would also seize his left eye after having already taken his right, Shisui made a crucial decision.
- Entrustment to Itachi: Shisui removed his remaining eye and gave it to Itachi Uchiha. He specifically asked Itachi to use it to protect Konoha, demonstrating his unwavering loyalty to his village even in his final moments.
- Safe-Keeping in a Crow: For its protection and to ensure it could be utilized for its intended purpose, the eye was implanted within a crow. This method ensured its mobility and concealed its presence, allowing Itachi to keep it secure until it was needed.
This particular eye, specifically the one given to Itachi, became a significant tool for him, stored within one of his summoned crows. Its placement within the crow was intended as a means of secure storage and deployment for future use in protecting Konoha, fulfilling Shisui's dying wish.
