Very closed off and private. Prefers to be alone most of the time but still somehow managed to gain friends throughout his not-cat life. A strong leader, dedicated to his friends, but due to his harsh upbringing, he has very little understanding of socially acceptable standards of violence and other harmful acts.

Yuma was born in the City, away from Not-Earth. He was separated from his litter days after he was born, by a curious little boy of a rich family. Unfortunately, the boy was ill, and only lived a couple of years after he adopted Yuma. The aftermath affected the boy's parents badly, and while they tolerated or were even kind to Yuma before, the tragedy left them broken and they projected their anger and sadness on the only thing capable of receiving it. After a couple years of mistreatment, the family finally kicked Yuma out, leaving him stranded out on the streets. Yuma would have surely died, were it not for Ethan, or the rest of his companions. He spent the following three years, slowly growing more and more adaptable and capable on the streets. He slowly gained more friends throughout the years as well, but it's still hard for him to open up to other not-cats. Despite this, when Nestor called him and his friends to their true home, it was unanimously decided that Yuma would be the leader of their village, Ephemeral.
