The Tanuki Team was created as an emergency response service by the corporate security
division of the Amagasa keiretsu to face the increasingly challenging operational scenarios posed by the colonization of Shinju, because their facilities were often isolated
and susceptible to all kinds of attacks from aggressive wildlife, raiders and thugs, rival
corporations, or tactical units belonging to foreign powers. Shurayuki was a contract killer
who drew the attention of the talent scouts of the Boro-cho, the intelligence service of
Greater Independent Japan. They offered her full immunity from prosecution in exchange
for her services on behalf of the country and the Emperor.
