Although he comes from an esteemed lineage, Ryosonuke himself is nothing remarkable. He was banished from his household and now makes a living as a tradesman. One day, his senior gives him a vampire doll, and when Ryosonuke's divided blood touches it, the doll awakens. He also gains a carnivorous girl after his senior's death. These two females assist Ryosonuke in managing the monster within him as he is targeted by different individuals for different purposes.
