The story is something like this a middle-age business man is a background character in a manga style story line. No face or name He spends his days admiring the hero's he passes in the street. All of them with faces and personalty. One day on his way to work a heroine is in danger. A speeding car hurdling toward her . At first He thinks someone will save her. No other hero's come, then He thinks what if she is suppose to die. I can't let that happen! He jumps out to save her. After the action he feels strange he looks in the mirror and he has a face. He becomes a hero. But at what cost?
