Perfect for you if...

You love dark romance with supernatural tension and aren't bothered by manga's stylised art style.
You want a slow-burn connection between two characters where the physical danger mirrors the emotional stakes.
You're after something shorter and punchier than a novel but with genuine relationship complexity.

Maybe not for you if...

You prefer Western comics or graphic novels over manga's visual language and panel flow.
You need a complete story arc in one volume rather than a serial that builds across multiple books.
You're looking for action-heavy plots where the romance is secondary, not intertwined with every scene.

About this book

Tsukasa, a college student, is rescued from an attack by a devil—a vampire capable of passing as human. Her rescuer, Anzai, is a half-devil who uses his supernatural abilities as a member of a covert police task force in Tokyo that investigates devil-related crimes. As Anzai takes on the role of Tsukasa's protector, the two develop a tentative connection. Anzai worries that this growing bond may challenge his strict personal rule against drinking human blood.
