The tenth installment of the Limit Amateur series features 22-year-old Yū, a beauty with a slim figure and delicate face. Though a female college student, through a chance adventurous encounter, she forgets her usual self and steps into a new realm of instinct. Seemingly innocent, she hides a surprisingly naughty side—playful and laughing, yet letting out shy moans as she strips away her clothes. Her honest emotions heighten her erotic charm. "You know, I'm actually really naughty. What's wrong with being sexy? Everyone's naughty—Yū-chan is naughty too."
