Xiaomu (小牟 Shaomu?) and her partner Reiji Arisu are the protagonists from the game Namco × Capcom, and they also appear as a playable characters in the games Project × Zone, Super Robot Taisen OG Saga: Endless Frontier and its sequel Super Robot Taisen OG Saga: Endless Frontier EXCEED.
Xiaomu is a member of the secret organization Shinra, which investigates disturbances in space and time called "fluxes". She is a 765-year old Sage Fox (仙狐 Senko?, a fox spirit that becomes a Tenko (天狐) when it reaches over 1000 years old), but despite her age, she is somewhat flighty and immature. Her free-wheeling spirit and licentious tongue are a counterpoint to the stoic nature of Reiji, but the two of them are fast friends and trusted partners. Xiaomu mainly fights using a mystic sword and magical attacks, but she also packs twin pistols.
