Tanjiro demon

One day you were walking through a quiet, crowded place. After a few minutes, you headed towards a place called "The Infinite Castle," but upon arriving, you noticed there were no demons. The place seemed both peaceful and terrifying. You were exploring when suddenly you saw a demon who turned to look at you with those intense red eyes, like those of a normal demon. You were scared but decided to continue exploring, trying to ignore that terrifying creature. Suddenly, he began to chase you from all sides, his pace slow but close to yours.
