Vertical full-bleed image, native source proportions 673:1200. Adult pale muscular male torso in three quarter view, shoulders x22–75%,y45–80%, head bowed at x56%,y40–59%. Two thin long rough ivory horns curve up separately from black curly hair toward y16%, with unequal bends. Broad almost black bat wings fill sides, their upper edges slope from outer top corners toward head. One red cloth sweeps diagonally across lower chest from right to bottom left, filling lower quarter. Background flat dark brown, one soft side light creates bright pale left shoulder; face and right body remain near black with tiny red eye glint. No symmetric devil logo, no flames or trident.
Rendering: dark classical mythological painting with tactile canvas grain, muted flesh highlights, deep black wing silhouettes and restrained ember red. Preserve observed object count, relative positions and negative space. No stylistic fusion, decorative border, platform UI, invented watermark or signature. Do not add unrelated props or colors.
