Long ago, spirits and mortals coexisted, but greed and betrayal led to the rise of the Mad King, Azazel. Sealed away in a final battle, his reign of terror faded into legend—along with the Artifact that once defied him. Now, whispers of its return stir the world once more… In a quiet orphanage, Yuko dreams of adventure, captivated by the legends of lost Artifacts. She and her best friend, Yuudai, train for years alongside their companions, Sumiye and Daisuke, yearning to see the world beyond their small village. When a cult begins attacking the kingdom, seeking to resurrect Azazel, fate offers them a chance to leave—an opportunity wrapped in danger, mystery, and the promise of discovery. With the world on the brink of chaos, Yuko and Yuudai set out on a journey that will lead them to ancient ruins, forgotten secrets, and the truth behind the Artifact that once shaped history.
