Sonken Chuubou

Second sister of the Son family, unlike Sonsaku, she is less ruthless, uneasy about herself, and more kind-hearted. She worries about how her sister's wars are affecting everyone while, unknown to her, her sister is doing this for her sake. Sonsaku has chosen her to be next-in-line to the throne; she knows that she will be a better ruler who will heal the wounds the nation has suffered from the wars.
