Ari has jet hair in a ponytail and hazel colored eyes. Before becoming a soldier he wore a brown outfit with ash gray colored sleeves, a black colored belt, ash gray pants, and brown shoes. He later would wear a red scarf, chainmail outfit, and helmet.
Ari showed deep resentment towards a person who caused his brother to become disabled by cutting off his left leg. Otherwise, he’s an ambitious warrior and is infatuated with Ylva.
