He's coming for you (part 1)

I decided to go for a walk. It took me a few blocks before I felt it, this overwhelming sense that someone was watching me. I couldn't help but to look around, first left then right, then behind me. There was nothing there. With a sigh I just figured it was my paranoia again. I tried to ignore it as the breeze made my baggy gym shorts blow in the wind. A few cars went by before I heard something to confirm my suspicions. I could hear what sounded like footsteps not far behind me. I quickly turned around but I could find nothing there, where I swear I heard the foot steps. I didn't know what was going on though I figured it had to be all in my head. I kicked a rock half way to the convenient store. Then I heard an unmistakeably heavy breathing. I shook my head to clear it and passed it off as paranoia yet again. It wasn't long before I could feel that heavy breath down my neck. I ran to the convincing store. When I got into the store I was out of breath but the breath down my neck was finally gone. I looked at the old store owner behind the counter. I'd never been so grateful to a complete stranger. I got the milk and bread for the house that my mother asked though I wasn't ready to go back out there, alone. I just knew what ever was breathing down my neck would come back. I could never have just imagined that! Though I didn't know what to do. I couldn't stay in the store forever. So I had to talk to the clerk.
"Sir?" I asked politely. "Did you see anyone behind me when I walked in?" I asked him looking nervously out the window of the doors. The man simply gave me this wide eyed look as if saying 'yes, and you're screwed.' which was oh, so reassuring. "What did you see?" I couldn't help but ask him. After all, what ever it was, I couldn't manage to turn around fast enough to see it. 
The man simply shook his head and I gave him a look that said 'REALLY?' The man then sighed and opened his mouth to talk, he must have changed his mind for some reason, thankfully. "He... he was behind you. Breathing down your neck. He's coming for you." The man said with an accent I could not recognize. While the man was telling me this he was pointing behind me somewhere. When I looked I could see some sort of religious symbol on a shelf. On it was a what looked like an old man, who happened to be red all over with dripping fangs coming from his mouth.
Of course my question was, "Who is he?" I asked holding the little painted display. 
The man's first response was definitely in another language. One that I never so much as heard of. Then he corrected himself by translating it into English. "The god of punishment, or torment." He told me then backed away from me as if I had some kind of incurable disease. The key word being incurable. I was panicking, I didn't know what to do. Then suddenly, out the window of the continent store I could see him, he was waiting for me. I couldn't stay there forever.
