Kirigakure.
Obito was handling official business in the Mizukage's Office, enjoying the status of Mizukage while helping build Kirigakure.
Ever since he'd used his Mangekyō Sharingan to control Fourth Mizukage Karatachi Yagura, he'd been impersonating the Mizukage for several years. During that time, he'd enacted numerous policies targeting the Kekkei Genkai Families, successfully plunging Kirigakure into a prolonged Civil War.

Pulling his wandering thoughts back, Obito took out the roster of Mist Hidden Anbu and began looking for
