She is a dragon priestess of "Kagero", one of the two major armies of the Empire. "The Ears of Dragon General" is an ability to understand all dragons' words and deliver one's own voice to dragons afar, and "Marcel" is an apprentice dragon priestess of a tribe that inherits this special ability. She is allowed to participate in actual battles at this young age because her ability is the strongest among the tribe's members. If she wishes, she can speak with dragons a hundred miles away from her. Even so, she is considered an "apprentice", because her mind and body cannot catch up with the ability---in other words, she cannot control the ability well. Since she had once used the ability recklessly, she is always accompanied by someone to watch over her. She is thankful that others are caring for her, but she feels bored... these are the mixed feelings of this young girl of her age.
