Stark is a Human Warrior. After his village was attacked by Demons, he fled and joined Frieren's party as their vanguard.
Stark has spiky, black and red dual-tone hair and orange eyes. He typically wears a collared black sleeveless shirt along with black pants and a white sash around his waist, and wraps bandages around his arms. When he is out, he wears a red coat and black fingerless gloves, and straps his weapon, a large axe, to his back with a belt. He wears a silver bracelet that he received as a birthday gift from Fern on his wrist.
