Because Yuma died in the war he participated in and his father found him. In order to save him he used all his trion to make a black trigger (ring) and put Yuma's body inside it, to slow down the rotting of his body. As he did that Yuma's body was replaced with a trion body making his hair turn white and not being able to age.
