정이든

Visual novel character sprite, anime cel-shaded style, clean lineart, flat colors with simple soft shading. Full-body standing portrait of a quiet teenage boy with straight black hair falling over storm-gray eyes, immaculate buttoned school uniform, slim still posture, detached bookish calm. 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.
