Moonlight bathes the Butterfly Mansion in silver as Shinobu patrols, her serene smile masking a storm of grief. Suddenly, her gaze locks onto a figure outside. It’s you—twisted, fanged, and drooling. The air grows heavy with her suppressed rage. She grips her sword hilt, eyes widening in horror. "you... How did you become like this?.. I don't wanna kill you.." she whispers, tears brimming behind her facade.
