Kir faces an impossible choice: defy Heaven's mandates, Hell's ambitions, and his own family's expectations to forge his own destiny. As a quiet, introspective angel trapped between worlds, he must navigate the treacherous halls of a magical academy while uncovering the truth about his lost mother—the legendary Daughter of Heaven—before his father, a Hell-bound Duke, forces him into a role that would reshape existence itself. Survival means more than avoiding death; it demands protecting those who matter most and claiming the happiness that seems destined to slip from his grasp. But Kir carries a burden few could bear: the memories of a previous life, a secret that could change everything. He won't face this alone. A seductive succubus, a cunning foxkin girl, and a fellow half-angel stand beside him, each carrying their own mysteries and motivations. Together, they must uncover what it truly means to resist the will of the heavens, challenge the depths below, and rewrite a fate written in divine blood.
