At this servant detention facility, unruly servants sent by Mistresses for re-education are transformed into evolved servants capable of fulfilling their masters' desires. Through relentless discipline, these servants develop unbreakable spirit, loyalty, and resilient bodies able to endure even the harshest play, while their patience is systematically broken down. The female instructors at the facility are harsh and cruel, using re-education as an excuse to subject servants to severe training and abuse, all to satisfy their own pleasure. Today, three new servants have arrived, and their re-education begins—no matter how loudly they cry out, there will be no stopping it.
