"A blonde-hair with blue eyes, An expert swordswoman with unparalleled beauty, Ferris, who comes from a famous Swords-Clan designated to serve as guards to the King of Roland, is the heroine of the story. She carries a typically emotionless expression, and is extremely proud of her own beauty. She is fanatic about dongo and can do almost anything for the sake of them."  

Ferris is the main female character. She is usually in any scene that has Ryner in it. Ferris is very foward with her speech, she gets straight to the point. She is around 19 I would assume. Ferris is kind of in between of loud and average noise level.
