Song of the Night Walkers

Kou Yamori, a seemingly ordinary middle school student, is tired of pretending and decides to quit school. However, this decision leads to insomnia as he lacks daytime activities. To find solace, he takes walks alone at night, temporarily easing his restlessness. During one of these walks, he encounters Nazuna Nanakusa, a peculiar girl who identifies the root cause of his insomnia. She explains that he can only sleep peacefully if he embraces true freedom and lives life to the fullest. Feeling relieved, Kou follows Nazuna to her apartment, where she invites him to share her futon. Unbeknownst to her, Kou pretends to be asleep, and to his surprise, Nazuna leans over him and bites his neck.
