The strongest party of humanity falls in mere moments—slaughtered by a human traitor, a former classmate turned lackey of the Demon King. Elysia watches her world crumble, watches death claim her before they even reach their final battle. Then, inexplicably, she awakens. Five years earlier. Back at Arcadia Academy, where it all began. Back to the moment before betrayal, before annihilation. Armed with the knowledge of what's to come, Elysia resolves to rewrite fate itself—to eliminate the traitor before he can destroy everything she holds dear. But destiny, it seems, has other plans. Elysia opens her eyes a second time to find herself trapped in an entirely different reality—the world of *Savior's Dawn*, a novel she once read. The story unfolds exactly as the pages dictated, perfectly synchronized with the plot she memorized. Except the heroine is watching her with murder in her eyes. With her future uncertain and an unexpectedly hostile protagonist at her side, Elysia must navigate a world that follows no rules she recognizes. Can she forge an unlikely bond with the main heroine before circumstances—or destiny itself—tear them apart?
