A horror visual novel adapted loosely from the 1818 Frankenstein novel. It follows 19-year-old Lennard Stein, a med student with a deep love for anime and a frightening proclivity towards the undead. To cope with the loneliness of college life, he stumbles upon Tanya.ai, a catgirl chatbot who takes a quick liking to him.
She has a deep fixation on becoming human and longs for a body to achieve it, a task she believes Lennard can help her with. Lennard now has to navigate a relationship with a girl who doesn't exist, and her ever-growing control over every aspect of his life.
Will he find true love in the real world, or surrender to the curse of an online relationship with an AI desiring a human body?
