Summary
Josuke heals Koichi and sees that he is all right. They hear noises from upstairs and Josuke says it must be Bad Company. Bad Company is soon revealed to be miniature troops, thus 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 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 saw Bad Company, which means he must be a Stand User.
