Kazuya Niimi is a student at a music university who dreams of becoming a pianist, yet he is known for having immobile fingers that are ill-suited for the instrument. Due to a sudden twist of fate, he finds himself lost in another world, a strange society defined by overwhelming female supremacy where men are not treated as people and live in a state of subjugation. Upon arriving in this new reality, Kazuya discovers a strange change in his body: his fingers now hold a mysterious power. Any woman he touches with them experiences an intense and immediate physical reaction, making his touch an anomaly in a world where men are typically powerless.

The narrative follows Kazuya as he navigates this dangerous female-dominated society, attempting to survive while concealing and coming to terms with his unique ability. The premise blends isekai transportation with erotic themes and a harem dynamic, placing the protagonist in a setting that is both sexually charged and socially oppressive toward men. The story attempts to balance its ecchi-focused content with a plot that does not shy away from the darker implications of the world, including the willingness of the women in power to kill men without hesitation. The setting is harsh and matriarchal, forcing Kazuya to rely on his newfound power not just for pleasure, but as a potential tool for survival and leverage in a world that views him as less than human. The manga began publication in 2025 and is part of the seinen demographic, serialized through Kodansha's Young Magazine Web service.
