What Are You Doing Here, Evil God?

Behind him, Shabu, who was lying on the ground, had already lost his initial arrogance. With his face covered in blood and flesh, he tried his best to speak. "Devil..." "You are the devil..." Hearing this, Lonaya paused. Then, he turned back and said with a smile: "Devil?" "No, no, you shouldn't call me that. I'm not that kind of trash." "I actually..." "It's an evil god." "So, I don't quite understand your human feelings." The corners of his mouth raised slightly, and he stepped on it again. … What are you doing here, evil god? This is a detective story. At the end of the journey, will he become the evil god who destroys the world, or will he become a passer-by who disappears among the crowd?
