Masca: The Beginning

This manga serves as a prequel to a larger series, detailing the transformation of Caien into a demon lord. It explores his connection with Rakin, the King of Speira, and the romantic tensions between Rakin, Caien, and Rea, a member of the mascan race. Asarella is also present in the story, though the focus remains primarily on Rakin and Rea's relationship.
