Heaven's Mandate

In the divine kingdom of Empyrea, where rulers claim the blessing of heaven itself, 16 year old orphan Kuroya Yuechen hides a forbidden power: Getsumeiton, the eclipsed moon Seiki feared even by the clan that birthed it. When the King unexpectedly arrives to select three children - ages sixteen to eighteen - to be his 17 year old son Kōmyō Amateru's fiancé, Yuechen is thrust into a world of radiant courts, sacred expectations, and a crown prince whose light is said to be heaven's own.

But Empyrea's brilliance casts long shadows.

As Yuechen's presence disrupts the kingdom's divine order, ancient prophecies stir, political tensions rise, and the truth behind Empyrea's "heaven‑given" rule begins to fracture. Bound by fate to Prince Amateru, Yuechen must decide whether he is the kingdom's salvation... or the eclipse destined to end its light.
