In a world where advanced technology rules, humanity creates its first perfect human: Shiki. Born in a world filled with secrets, Shiki is not just a marvel of technology but the key to unlocking the mysteries of the lost city. As he navigates through the complex halls of Aeternus Academy, where the best minds in the world train to protect and preserve civilization, Shiki discovers that his existence has a greater purpose—a duty tied to the survival of humanity itself. But Shiki's journey is not without peril. A dark force, buried in the shadows of history, emerges to challenge everything he knows. With the help of his creator, Dr. Kimura, and a group of unlikely allies, Shiki must confront the truth of his creation and the destiny that awaits him. The balance of the world lies in the hands of the Guardians, and Shiki must decide where his loyalty truly lies. Will Shiki rise to fulfill his purpose, or will he fall, leaving the lost city—and the world—to be consumed by chaos?
