Under the strict guidance of Dominatrix Kira, a male masochist seeking to become a true devoted servant comes to her. Using even ○-prohibited servants, she repeatedly subjects this man to brainwashing and rigorous training to transform him into a genuine, authentic servant, forging both unbreakable mental fortitude and a body capable of enduring extreme torment. For anal stretching, three types of oversized dildos and double fisting are employed, while diverse restraints include being bound into a human chair with duct tape and plastic wrap. Further torment includes anal stretching using boots and feet, penis bondage fisting on a guillotine rack, high-pressure enema devices forcing piss drinking, and electric torture via penile urethral electrodes—each session merging extreme pain with perverse pleasure. Additionally, various torture devices are utilized: duct tape chastity belts, spread-eagle punishment on a triangle bench, suspended human swing, human horseback riding, massive candle wax torture, sack bondage, anal stretching with an oversized speculum, and final purification rituals involving holy water.
