FTKD-042 In class, she's a serious, nerdy, unassuming girl (with hidden large breasts), but she's actually a pervert who always calls me out after gym class or after club activities, wanting to secretly release the adrenaline pumping from exercise through sex. - Yamashita Sawa - Sawa Yamashita

Yamashita's characteristics: He speaks in a low, mumbled voice / His posture is slightly inward / He walks with his shoulders hunched and his back slightly hunched, and he doesn't swing his arms much / He doesn't make eye contact very often. This nerdy, introverted Yamashita was a perverted prankster who enjoyed teasing people with erotic techniques (fantasies) honed from reading erotic manga and using vulgar, obscene language, continuing to torment them no matter how many times they ejaculated, and making them ejaculate again and again!
