Mistress Youku, a reputable and well respected Mistress in Japan, well-known for her strict and grueling training of her slaves, is enjoying her day off, when out of the blue, she receives a call from one of her Mistress friends who she recently lent a slave to. Her friend explains to her that while she was initially ecstatic with her borrowed slave, though she is no happy that the slave is defective. He does not obey command and can hardly take any punishment. With this news, Mistress Youku apologizes, and ask for the slave to be sent back at once for retraining.

When the defective slave returns, Mistress Youku is furious! Clad in boxing gloves and shin guards, greets him with a ferocious kick to the nuts, immediately dropping the worthless man to his knees and gasping for breath. She orders the pathetic man to stand up straight away, he must be punished for disgracing her reputation. He is hit with a barrage of brutal blows to the face, body and head, making him once again drop to the floor, where he is maliciously kicked in the face non stop and knocked back down, every time he is commanded to get back to his feet.

The worthless slave is fiercely smacked in the face by his sadistic slave trainer before the weak man drops onto his back in submission, where he is also viciously kicked and berated for being a pitiful, pain-intolerant punching bag. She barbarically pounds at his face until he's severely swollen and bruised, before dragging and placing him against a wall where she can accurately pummel and stomp on the useless man.

Is this rigorous training going to be enough this time?
