마준서

Visual novel character sprite, anime cel-shaded style, clean lineart, flat colors with simple soft shading. Full-body standing portrait of a Joseon military officer with black hair in a neat topknot under a gat-less formal headband, deep blue martial robe with a sword at the waist, disciplined warrior posture. 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.
