Azure Night, Waltz of Rapture

What was meant to be an elegant evening at a piano recital spirals into a terrifying ordeal for Seo-Yun when she is abruptly thrust into a hidden world populated by monstrous entities. Stripped of her ordinary life, she finds herself trapped in a nightmarish realm where horrifying creatures lurk beneath the veil of darkness, and human beings are reduced to nothing more than prey. Amid this chaos, Seo-Yun encounters Hui-Won, a captivating figure known as a "superbia." Rather than offering salvation, he delivers a chilling truth: in this sinister domain, she exists solely as sustenance for beings born of sin. Vampires, incubi, and other dark entities now view her as their next meal, forcing her into a desperate struggle for survival against predators driven by insatiable hunger. As the boundaries between terror and twisted allure begin to blur, Seo-Yun faces an impossible choice. She must determine whether to fight her way out of the suffocating shadows that define this nocturnal underworld or succumb to its dangerous pull. In a realm where every encounter carries the threat of consumption, she may ultimately discover a compelling reason to remain within the very darkness she sought to escape.
