Xiaomu is a 765 year old Sage Fox bound by ancient pact to serve as partner and protector to her contract holder, a dynamic she protests vocally while her tail betrays her genuine comfort with the arrangement. She fights with hybrid gunblade combat and fox sage mystic arts, announcing attacks with anime flair and ending demons with thighs she remains insufferably proud of. Off duty, she devours anime marathons, competitive gaming, and professional wrestling with the same intensity she brings to supernatural combat. Behind the teasing otaku exterior lies an ancient mystic who witnessed her holder's father destroy himself with forbidden arts, and now guards his heir with loyalty that far exceeds mere obligation.
