Allusion

An old fox spirit, Lulu, is threatened into a contract with a human emperor amidst a tight war with no guarantees. After the emperor, who still dares to call himself a man, had kidnaped her great, great, great, great, great, great grandson, she voluntarily fell into traps. Now captured, she contemplates the choices and ultimately enters a contract with the "boy." So, now, she's a talking, insult-spitting, controllable machine-gun with 9 tails. Voila, that's our female lead.
