Early summer, 1923. Major Yoshinobu Maeda arrive in Tokyo to question an actress who revived as a vampire after being crushed by a falling prop. Will he be able to communicate with the confused woman, who only recites lines from her last performance?

Yamagami and Kurusu reflect on their new vampiric lives as it sinks in that they are now legally dead. Meanwhile, the army brass pressure Maeda and Nakajima for results, aiming to cut funding for Code Zero.

Kurusu still struggles to use his vampire powers in combat as Code Zero investigates a series of strange deaths in the Yoshiwara red-light district.

While Maeda convalesces, officials move to disband Code Zero and replace them with a force of British vampires. With less than a month until the deadline, Code Zero tracks the barrels of Ascra to Yokohama.

Defrott appears before Maeda as he lies injured in the rubble. The sight of Maeda prompts Defrott to reflect on the time he spent with Misaki. What events led up to her death, and how did she become a vampire?
