Kagami Uchiha

Kagami was a fair-skinned man with short, black, tousled hair which fell over around his forehead protector, framing his face. The anime actually depicts Kagami's hair a bit more kept. During the First Shinobi World War, he wore the standard Konoha outfit of the time which consisted of a black suit with grey armour covering the chest, thighs, and shoulders, arm guards, a forehead protector, a kunai holster on his right upper leg, a pair of chainmail armor on his lower legs, sandals, and a pouch strapped to his lower back with bandages. At other times, his attire was that typical to the Uchiha clan and included a high-collared, dark-coloured shirt. In the anime when he was a child during the village's founding, he was seen wearing a typical high collared black Uchiha shirt with a clan symbol on the back, grey pants, bandages around his arms and legs, and black shinobi sandals.

In the anime, Kagami was amongst the first few hundred of students to attend and graduate the Academy. Having become friends with Danzō Shimura and Hiruzen Sarutobi, he saved the former many times with his dōjutsu. During the First Shinobi World War, he and his teammates from the Escort Unit accompanied the Second Hokage on a mission. Pursued and ultimately surrounded by Kumogakure's Kinkaku Squad, the group discussed their options, where Kagami noted that Koharu's plan of an ambush wouldn't work and that instead, a diversion was needed to lure the enemy away. He then listened as the Second Hokage, who had nominated himself as the decoy, appointed Hiruzen as the Third Hokage. At some point, Kagami became a father, and at the age of 25 died. His only known direct descendant Shisui would go on to inherit his Will of Fire rather than the Uchiha's Curse of Hatred.
