Kagami Uchiha

Kagami is remembered as loyal, dependable, and free from the extreme hatred that affects some members of his clan.

His commitment to Konoha earns the respect of Tobirama, a leader otherwise known for his caution regarding the Uchiha clan.

Anime material depicts Kagami as a friend of Hiruzen and Danzo and states that he repeatedly uses his dojutsu to save Danzo during their careers.

His legacy later becomes important because his descendant Shisui demonstrates a similarly strong attachment to the village.

Kagami possesses the Sharingan, granting heightened perception, the ability to read movements, and powerful visual genjutsu potential.

Although few of his individual battles are shown, Tobirama's willingness to include him in his personal Escort Unit indicates very high ability.

Kagami serves as a jounin during the First Shinobi World War, placing him among an elite group of Konoha fighters operating directly under the Hokage.

Kagami appears primarily through flashbacks to Konoha's earlier generations.

During the First Shinobi World War, he accompanies Tobirama's Escort Unit when the group is pursued by Kumogakure's Kinkaku Force.

Kagami participates in the discussion over who should serve as a diversion so that the others can escape.

Tobirama ultimately chooses himself and appoints Hiruzen as the Third Hokage before confronting the enemy force.

Kagami's historical importance also lies in showing that Tobirama did trust individual Uchiha who placed the village above clan resentment.

Tobirama Senju is Kagami's Hokage and commander in the Escort Unit.

Hiruzen Sarutobi is Kagami's teammate and friend.

Danzo Shimura serves alongside Kagami and, in anime material, is repeatedly saved by Kagami's Sharingan.

Shisui Uchiha is Kagami's descendant and inherits a similarly strong Will of Fire.

Koharu Utatane, Homura Mitokado, and Torifu Akimichi are fellow members of Tobirama's Escort Unit.
