Two Sides of the Door

"A red outfit, is he the owner of this building?"

Inside this blood red city, the buildings were the most dangerous because no one knew what was hiding inside them. Each building was an unknown. The man in the doctor's coat was very strong, but even as strong as he was, he did not dare to step into these buildings willy-nilly. The most extreme red was still a Red Specter, but the man knew that hiding in a corner of this city was a presence greater than a Red Specter.

He did not know how to describe it because he had not seen it before, but he could sense its presence. It was an overwhelming presence; every vein in his body felt like exploding, and his hair stood on end. At that moment, he even forgot that he had become a ghost. Before such a presence, human, ghost, Red Specter… there was no difference.
