Yura is the type of cute, fresh-faced girl who would fit right into a popular idol group, and her sweet personality, respect for elders, and devotion to her family paint her as a classic good girl. Yet, perhaps as a reaction to her upright upbringing or simply due to her trusting nature, she has become the top student in her class—and also a complete sex slave, obediently submitting to older men. The training is already complete: she now cums repeatedly while spewing out shameless, depraved words that she'd never dare say in front of her father. Inside her lies a fusion of the pure, proper girl everyone sees and a deeply erotic, hidden side that craves domination.
