Shorinji Kawasaki, who was active in erotic activities on social media, met a dental hygienist at a NicoNico video offline event and developed an intimate relationship, resulting in the leak of their gonzo sex recordings. Among these, particular attention was drawn to Wakana, a 20-year-old from Kansai living in Yokohama. Though she has only had three partners, her sexual enthusiasm is extremely high, and she diligently responded to every erotic demand made by Kawasaki. The video features a variety of scenes including thrilling moans in confined spaces, teasing endurance acts, masturbation to climax from 130 meters above ground, erotic martial arts play using her specialty in karate, and wet, messy, extreme perverted acts. It also captures Wakana screaming in ecstasy during creampie sex that nearly crossed legal boundaries.
