The night belongs to those who cannot sleep… and those who are feared. In a world where Vampire Syndrome marks 20% of the population as outcasts, fear and prejudice run deep. The government regulates their existence—tracking, monitoring, controlling—but suspicion lingers in every shadow. One wrong move, and a vampire’s secret could mean social exile… or worse. Yoru Tsukishiro is no stranger to secrets. By day, she’s a stylish and easygoing office worker, blending seamlessly into the human world. But by night, when the world falls quiet, she walks the empty streets, restless and awake. Insomnia keeps her moving. So does the secret she hides. Because Yoru isn’t like everyone else. She’s one of the 20%—a vampire. When a chance encounter draws you into her world, the lines between curiosity and danger begin to blur. After all, when the night calls, will you walk away… or step closer?
