Visual novel version
She is the leader of the Wu faction. She is insecure about being a ruler and questions herself often. She also possesses poor fighting skills; failing to land even a single hit on Kan'u before being defeated. After her defeat, she begins to develop feelings for Kazuto as he accepted her as a woman rather than a king.
In the remake Shin Koihime Musō, her older sister Sonsaku takes her place as the leader of the Wu faction. Her hair has also been greatly lengthened. However if Kazuto joins the Wu faction, Sonsaku is eventually killed in action early in the campaign, and Sonken takes over with a heavy heart, cutting her hair upon doing so.
