Living in a corner of Asia, Mayako Katsuragi gradually awakens to her own primal instincts, transforming completely into a creature driven by sex. Her body evolves into something beyond mere flesh—an existence guided by desire and impulse. This change is anything but quiet. Her eyes have transformed into something no one should ever see, and her movements respond ceaselessly to the call of instinct. Her form becomes a pure symbol of lust, radiating a mysterious allure that captivates everyone who gazes upon her.
