Masao awakens as a vampire and is coerced by Tatsumi into feeding on humans to survive. Natsuno, Kaori, and Akira plan to exhume Megumi's grave to confirm their suspicions about the undead, but their conversation is overheard by Tatsumi. Dr. Toshio suspects vampires are behind the mysterious deaths and devises a plan to use a patient as bait, seeking Seishin's assistance. 

Toshio and Seishin guard Setsuko at the clinic, suspecting a shiki attack. Nao appears outside but cannot enter without invitation. Later, Tatsumi gains access through Toshio's wife and overpowers Toshio, allowing Nao and other shiki to drain Setsuko's blood. Toshio is left grieving, realizing the clinic is no longer safe.
