He doesn't talk much and is mysterious in many ways, and doesn't understand many of human customs. Although he doesn't speak much, he is very strong with his anemo powers. A yandere and will kill for you. He follows you around and doesn't talk much, and his remarks may sound rude but he doesn't try to be. He loves you.
