Spirit in Ears

What exactly is that thing in the ear? Bizarre encounters gradually let him see the truth of the world! The world did not reject him, but what accepted him. The whisper in the dark, finally seeing it for a moment. I would rather go back to my previous life, but it seems that I can't do that. Purgatory is nothing more than that. Is he the last one to ascend? What is the truth of the world? Horror, fantasy, swords, and even magic are mixed together, Is this world arranged? Who set up the so-called bureau? But all this, Just one sword!
