Summary
Josuke heals Koichi and is relieved to find him still alive. They hear noises from upstairs, and Josuke says it must be Bad Company. Using the lighter to brighten the room, he sees what appears to be toy-like miniature troops, deducing that must be Bad Company's form and that the holes were caused by their rifles. Koichi and Josuke run away from the infantry and are about to jump out of the window when Josuke notices there are Apache assault helicopters as well. Josuke almost gets hit by a miniature tank but Koichi tells him to watch out. After Crazy Diamond deflects all the missiles Josuke suddenly realizes that Koichi is able to see Bad Company, meaning that he must now be a Stand User.
