character: sakurai_ruka, A medium shot from a low angle captures Ruka, a pale girl, crouching low against a cold tiled wall in a derelict hospital corridor at night. Ruka has long wavy black hair and pale lavender-gray eyes, wearing a black Victorian high-neck long dress; she presses one gloved hand tightly over her mouth to silence her breathing while her other hand clutches a flashlight against her chest, her wide eyes filled with tense fear. Far down the long, dark corridor behind her, a swaying surgical lamp and a vague white silhouette of a ghostly nurse suggest a looming presence. The environment is filled with cold clinical shadows and derelict hospital debris, broken only by faint, flickering red emergency lights overhead. The atmosphere is one of pure survival horror and cinematic tension, featuring high-contrast lighting where only Ruka's pale face and the distant white uniform catch the dim light, creating a suffocating sense of dread.
