Call of the Night Filler List, Watch Order & Episode to Chapter Conversion

Kou Yamori is an ordinary middle school student who finds himself unable to understand the complicated idea of love. Seeing no meaning in conforming to what is considered normal, he eventually stops attending school altogether. Troubled by sleeplessness brought on by his aimless days, Kou starts wandering the empty streets late at night.

During one of these nightly walks, Kou meets a strange girl named Nazuna Nanakusa, who claims that people stay awake at night because they are dissatisfied with how they lived their day and cannot sleep until they free themselves from their restraints. Nazuna offers to help Kou overcome his insomnia and invites him to her home, where she persuades him to lie down beside her on a futon. Uncomfortable with the situation, Kou only pretends to fall asleep—until Nazuna suddenly bites his neck, revealing that she is actually a vampire.

Although Kou initially believes the bite will immediately turn him into a vampire, the transformation proves to be more complicated. To truly change, he must be bitten by someone he genuinely loves. Determined to escape his dull human existence, Kou sets himself a new objective: to fall in love with Nazuna and become a vampire himself.
