one punch man

A bald man in a brown coat with a fur-lined hood stands with a neutral expression, his right hand clenched into a fist, then the scene cuts to a man with spiky blonde hair in a dark coat, who turns and walks away, followed by a man with spiky black hair in a purple coat who smiles and walks forward, then the scene returns to the blonde man walking away, and finally back to the bald man standing still, all against a plain white background.
