Anime version
Sōsō's trusted adviser and strategist who wears a cat-ears headpiece. She is in love with Sōsō and does not mind being teased by her. She has a rivalry with the Kakō sisters due to the fact they are Sōsō's cousins and are closer to her.

Visual Novel Version
The strategist of the Gi kingdom. Out of all of Sōsō's subordinates, she is most likely the one who enjoys being teased by her the most. She starts to develop a small rivalry with Kazuto for Sōsō's attention after being captured (in the first game) or when Kazuto serves as Sōsō's advisor (in the sequel Shin Koihime Musō).
