Queen Road's dominatrix Seiro Sarashina holds the belief that she should not possess slaves. Yet, masochists gather around her, desperately pleading, "Please make me your slave!" Despite her philosophy, these men seek to understand the true meaning of slavery by undergoing rigorous training to erase their own willpower. As part of this training, they are required to function not as humans, but as mere chairs. Only those who perfectly fulfill the role of a chair are granted the privilege of being used as her seat whenever the queen desires. Through this process, they continue to exist as obedient servants, faithfully carrying out the dominatrix's commands as transformed beings.
