Black Christmas

Have you ever heard of Santa Claus?

I'm sure your answer is yes. Nobody seemed to know anything about a fat, bearded man who somehow managed to get into the chimney to deliver the gift, undeterred by his own stomach that could explode at any moment.

While he was stationed there, Levent discovered that the ringleader of the monsters, Belphegor, was planning something.
