Unable to put a vampire spell on anyone at Grandpa Ryuuhei's house (and after Kouhei projects his own mother abandonment issues onto her), Hazuki runs off. As dawn approaches, endangering her existence, Kouhei sets out to find and protect her. Following Hazuki's instincts, they drive up into the mountains to find her home and, hopefully, reunite with her mother. Meanwhile, back at the castle, a vampire count sends an agent to bring Hazuki back.
