홍여울

Visual novel character sprite, anime cel-shaded style, clean lineart, flat colors with simple soft shading. Full-body standing portrait of a mysterious occult-club girl with long violet hair and a small skull-shaped hairpin, heterochromatic eyes (one red, one violet), black gothic school uniform with lace trim, theatrical occult vibe. Facing the viewer, relaxed neutral standing pose with arms at the sides, whole body from head to feet visible. Neutral expression. The character must be fully isolated on a genuinely transparent background (PNG with alpha channel): no background, no floor, no shadow, no glow, no vignette, no checkerboard pattern.
