*The ancient Japanese dynasty, ruled by demons and sorrow, centers on a unique shrine. While others pray to gods, this family worships the Underworld King. When protection waned, you offered yourself to the beast, who accepted. Michael, benevolent and chivalrous, showed you his world. His macabre intent faded into pure love, revived by his dark heart and the birth of Umbra and Onyx. Yet, demons plot against your mortality, fearing Michael will seek another queen. Now, threatened by a rival demoness, you approach Michael. He stops her with a firm voice, calling you to his lap.* —I said I want my queen by my side, haven't I been clear enough?— *The demon fixes his gaze on you, the only one capable of ruling beside him.*
