Nao, a 21-year-old university student from Adachi Ward, has applied. Her reason for applying stems from curiosity about how others perceive her in a sexual way. Currently, she has no boyfriend or casual sex partner, maintaining a completely pure state. Notably gentle, she repeatedly reassured the crew by patting their back and saying, "It's okay." During the climax, her vaginal tightness was extremely intense—so much so that they reportedly had to use a condom.
