Gyaru actress Asahina Mio is invited to Nakajima Enterprises, where the first half features affectionate foreplay and aggressive girl teasing to gradually lower her guard. The middle section shifts into a training session, with the bound gyaru girlfriend dominated using vibrators, forceful partying, and alcohol to enforce submission. In the latter half, she undergoes intense training through perverted reggae dancing and dildo deep throating on the floor. Ultimately, reduced to a compliant sex toy, she dutifully serves her master, bringing the story to a close.
