He probably should have stayed inside. The chaos and fighting that was going on was far different from the chaos he had seen just before the arrival of Nyx. But, Junpei had run out of sodas, junk food, and there was a new video game he wanted to get. He saw no harm in making a trip to the stores that were a mile away. Slipping on his earphones he begin the 1 mile walk to the store. He left his evolker at home, because he saw no reason to use it. After all, surely he wouldn't be killed.
He continued his trek making sure to avoid anyone that looked like they wanted to kill for no reason whatsoever. It started to get to the point that Junpei was wishing that he'd brought his evolker, just in case someone wanted to actually kill him for some reason. He bemoaned his stupid decision, but continued walking.
