Yui Yashiya 椰子谷唯

Holding Rank 1 in the Onishima Alliance and is the strongest member of its alliance after Douji. She has an interest in strong men, but she shows her feelings through acts of sadism, reveling in breaking their spirits. Under Rokudou's power, she sees him as an exaggeratedly strong man that progressively intensifies during their fight. Rokudou "defeats" her after rescuing her from falling out a window, causing his power to exaggerate his appearance so much that she faints in bliss. In the aftermath of the fight between the Onishima Alliance and Amori High, she leaves the Onishima Alliance. Part of her surname, Yashi, means Palm Tree.
