|Japanese name:||八頭司 颯姫|
Even though being usually cold and emotionless, she develops feelings for Yūto.
In Tsubasa Reservoir Chronicle: SpoilerIn Tokyo, she's one of the seven fighters of the City Hall action. Unlike in X, she studies medicine and is more no-nonsense than apathetic or heartless. She initially receives Syaoran's group with suspicion, but later treats their wounds.
