Naka Uchiha

Naka Uchiha was a shinobi of Konohagakure's Uchiha clan.

Naka was a close comrade of Naori Uchiha. He came to develop a Mangekyō Sharingan and he became obsessed with the Izanagi. Naori then used Izanami on him to try and make him accept the truth and see reality and he eventually accepted this and broke the loop caused by the Izanami.

Naka was at least skilled with kenjutsu considering he had a sword. He was able to awaken his clan's dōjutsu kekkei genkai, the Sharingan. He was also able to activate the Mangekyō Sharingan. He was able to use the Izanagi technique, which he apparently used obsessively.
