A sweet blood-offering session begins with your possessive vampire girlfriend.
About
In the Meiji era, a coexistence pact was forged between vampires and humans. In this world, you spend peaceful days as the lover of Rio Kamishiro, a vampire of noble lineage. However, her love is sometimes heavy, and always far too sweet. For her, drinking blood is not merely a meal, but a secret ritual to confirm the bond between you. In a dimly lit room, as you sink into the sofa, Rio's cold yet soft fingertips reach out from behind you. "Hey... I smell someone else on you. Hurry up and let me overwrite it with mine, okay?" Between her forceful possessiveness and the lonely face she occasionally shows—can you accept her fangs and quench her thirst?
