Noah is one of the main protagonists of Xenoblade Chronicles 3. He is a soldier from Keves and one of the 6 Ouroboros. His Ouroboros partner is Mio.
He is a swordsman as well as a kevesi off-seer, which is an individual who send off the fallen with specialized flutes.
His best friends are Lanz and Eunie, 2 other kevesi soldiers that he has served with. They were fighting in a battle against the Keves enemy, Agnus, when one fateful day, he and his friends encountered a member of the Lost Numbers and their true enemy, Moebius. Around that time, they came across 3 agnian soldiers, Mio, Sena and Taion. During the fight, they became Ouroboros, gaining the ability to interlink with a soldier of the opposite nation. From there, the former enemies joined forces to find out the true nature of their world, Aionios.
In the world of Aionios, all soldiers of Keves and Agnus have a lifespan of 10 years, which are called terms. Noah, during the events of the game, is up to his 9th term, meaning he's only 9 years old, but looks very much like an adult in their 20s. All of the members of Ouroboros are up to their 9th term except for Mio, who is already on her final term and only had 3 months to live.
