Anime version
Soso's cousin and one of her commanders. The elder twin of the Kakou Sisters, she is a strong, prideful, hotheaded person yet is understanding and loyal to her cousin whom she loves and understands her feelings.
Visual Novel Version
She is the elder sister of the Kako sisters and is also Soso's cousin and a commander of the Gi kingdom. She is strong on the battlefield, but is fairly dimwitted, shown by her lack of understanding the meanings of proverbs. Like many of Soso's subordinates, she enjoys being teased by her ruler. In the first game after becoming a captive of Shoku, she is greatly annoyed by Kazuto. In the sequel, Shin Koihime Muso, she tends to exhibit a somewhat childish behavor (like when she cried after dropping and damaging a precious object when a horseman passed too close to her), and she has an awkward view of Kazuto, with a tendency to blush while conversing with him, as if trying to hide any romantic feelings she may have towards him behind her strong steadfast front.
