Kayuu

A general for Toutaku. The equivalent of Hua Xiong.

Anime version
A brave general of the Dong army. This silver-haired beauty has absolute confidence in her fighting skills. She is also easy going as she doesn't mind if her leader Tōtaku goes visiting commoners in disguise, as she believes it will help their country's welfare if she sees their problems through her own eyes.

Visual Novel Version
She is very proud of herself, requesting to lead the fight against the three kingdoms. She is killed fairly early in the game by Kan'u. In the sequel Shin Koihime Musō, she engages against whichever faction Kazuto is part of early in the campaign, but is defeated. She survives at the end of the Gi Campaign, whereas she is killed in action in either the Shu or Go campaigns.
