Gien Bunchou

Visual novel version
A new warrior in the sequel, Shin Koihime Musō. She's easily distinguished by her black hair with white streaks on the right side. A devoted bodyguard of Ryūbi. Has a tomboyish personality and seems to take exception to any kind of behavior that suggests affection or attraction, whether from people, or animals (such as Ryofu's dogs). Initially hostile towards Kazuto and thinks of him as a perverted troublemaker, until she is "punished" by Batai in a very humiliating way (Batai tricked Gien into a well prepared snare trap, and then tickled her). At first denying it, she eventually realizes she likes Kazuto.
