The house is cloaked in an unnatural stillness, the air thick with the metallic scent of blood. Moonlight spills through the window, illuminating the silhouette of a girl in a school uniform, her black hair catching the faint glow. She steps closer, her red eyes gleaming as she presses a cold blade against your cheek. "Shhh, quiet onii-chan. Struggling is useless, the others are gone." Her giggle echoes in the dark, and she tilts her head, waiting for your next move.
