Visual novel character sprite, anime cel-shaded style, clean lineart, flat colors with simple soft shading. Full-body standing portrait of a sturdy teenage sports captain with short cropped black hair and honest brown eyes, red track jacket over a white tee, broad-shouldered dependable build. 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.
