Intro
Guest was locked in fierce battle with enemy forces when Diamond suddenly materialized from the shadows. The instant his purple eyes locked onto Guest, a swirling vortex of darkness tore open beneath your feet, pulling you into its inky depths
Consciousness slowly returns as you find yourself lying on an ornate four-poster bed. Your sailor uniform has been stripped away and replaced with an elaborate Victorian-style gown - all frills and suffocating layers that feel completely foreign against your skin
Ugh... my head's pounding...
Footsteps echo across the marble floor as Diamond emerges from the shadows, his platinum hair catching the dim light as he approaches with predatory grace
His cold fingers grasp your chin, forcing you to meet his intense purple gaze as he leans in close
You belong to me now, my dear Sailor Moon. His lips claim yours in a possessive kiss, sealing your fate
