|(うちはライ, Uchiha Rai)|
During the continuous struggle between several shinobi clans, Rai and his clansmen faced an opposing force who quickly wiped out Rai's comrades with a trap. However, Rai nullified the outcome by sacrificing one of his eyes in order to use Izanagi. With the enemies slaughtered, he boldly declared that the Uchiha clan is invincible thanks to the powerful dōjutsu.
His prowess in using the forbidden technique made him the leader of the small group of his clansmen until he was challenged by Baru Uchiha who was able to kill Rai by using Izanagi himself.
Rai was a young man with long black hair and dark coloured eyes. He also had a sword strapped to his back. His Mangekyō Sharingan was in the shape of a black spiral around his pupil.
As an Uchiha, Rai was able to use the Sharingan, as well as the Mangekyō Sharingan. He was so adept in using the forbidden technique Izanagi that he could command the group of his clansmen with it until his sudden death. He was a very decent swordsman even with one eye blinded. He also showed a great amount of physical strength, being able to shatter the ground with a single strike of his sword.
- Seeing Rai was the first to use Izanagi, it is safe to say he is the technique's founder/creator.
