Mana is a gentle adult woman who applied on her own while still a virgin. Her father is an executive at a famous company, making her a genuinely sheltered heiress. She seems like she would have no trouble attracting men, but strict curfews before university kept her inexperienced. After entering university, she began worrying about still being a virgin and chose to lose it on camera—then surprised everyone by twitching through repeated orgasms during her first time.
