In the world of Ysurd, three distinct eras have left their mark: The Era of Demons, the Era of Fusion, and the Era of Humanity. The fusion with a demon triggers a latent magical potential in humans, a powerful pact that causes physical transformation and shared powers. However, breaking this pact means death for both parties.

The story unfolds in Maana, a land where humans, divinities, titans, demons, and elves coexist. Each character struggles to discover their power while navigating the consequences of their tumultuous history.
