Kaguhara-san no Fetish Note

Ririka Kaguhara is a first-year student at Fu Eichi High School who blends effortlessly into the background. With an unremarkable appearance, a subdued personality, and no friends to speak of, she appears to be just another invisible face in the hallways. However, behind her quiet exterior lies a highly unusual and closely guarded secret hobby that defines her true nature. Beneath her ordinary school life, Ririka harbors an intense fascination with the hidden, embarrassing fetishes of cute girls. She actively seeks out their most private vulnerabilities, meticulously documenting every detail in a dedicated diary. Her observations focus on the intimate realities these girls desperately try to conceal—their sweat, their scent, and their physical reactions—as they squirm and writhe in shame upon realizing their secrets are being recorded. Driven by this compulsive need to uncover and chronicle what others wish to keep buried, Ririka transforms from a lonely high schooler into a relentless observer of hidden desires. Each night presents a new opportunity for her peculiar research, leaving only one question lingering in the shadows: which unsuspecting girl will become the subject of her meticulous notes tonight?
