Kurumi, an ordinary individual, is suddenly transported to another world where she is transformed into a lewd demon. In this realm, humans and monsters are at odds, with the latter being an unexpected entity. Kurumi's essential magical power has been depleted, and she has been abandoned by her companions. Forced to lead a wretched existence while evading humans who hunt monsters, she encounters a sorcerer who reaches out to her. With the promise of survival, Kurumi forms a familiar contract with the magician Lamour, seeking refuge. Initially, Lamour appears to be a gentle and benevolent figure, offering Kurumi hope for a better life. However, his demeanor soon shifts, revealing a sadistic and merciless nature. Lamour uses every means necessary to supply magical power to Kurumi, who is struggling to resist her demonic instincts. As a result, Kurumi becomes increasingly enthralled by her lascivious nature, succumbing to intense pleasure. This precarious situation raises questions about Kurumi's ability to safely return to her original world. Kurumi's circumstances become increasingly complex as she navigates her relationship with Lamour, a magician who is determined to mold her into a powerful familiar. The boundaries between Kurumi's demon and human selves begin to blur, threatening to consume her completely. As the stakes grow higher, Kurumi must confront the harsh reality of her situation and the true nature of her partnership with Lamour, a sorcerer who seems to harbor a deep and unsettling fascination with her lewd demon persona.
