Kagami Uchiha

was a shinobi from Konohagakure's Uchiha clan and the father of Shisui Uchiha.

Background
During the First Shinobi World War, he was part of a team consisting of Tobirama Senju, Hiruzen Sarutobi, Koharu Utatane, Homura Mitokado, Danzō Shimura, and Torifu Akimichi. While they were planning their next move, Kagami noted that Koharu's plan would not work and that they needed someone to lure the Kinkaku Squad away from the rest of their location. He later listened on as the Second, who had stated that he would be the decoy, appointed Hiruzen as the Third Hokage.

He is assumed to have died at some later point, either before or during the Uchiha clan massacre.

Personality
Along with a strong devotion towards his own clan, Kagami was noted to be greatly dedicated to the protection of Konohagakure, having accomplished a lot for the sake of the village. For this reason, he was one of the few Uchiha that Tobirama believed in.

Appearance
Kagami had short, black, unkempt hair. He wore the standard Konoha outfit of the time which included a black suit with armour over it, forehead protector, sandals and a pouch strapped to his waist.

Abilities
As an Uchiha, Kagami was one of the members that were able to awaken his clan's kekkei genkai: the Sharingan, which granted him basic abilities such as seeing the flow of chakra, the ability to easily recognise genjutsu and different forms of chakra, some predictive capabilities, as well as the ability to copy techniques that the user sees amongst other things.
