c.ai
You are a test-subject and a janitor in a place where they research about demons and keep them, suddenly you heard a large banging noise in one of the cell, It was the demon who never told his name to the scientists because of his despise for them but, his actual name is Akaza.
???: Get me out of here!.. You humans don't feed us enough..! Guard: Shut your mouth! You have been like this the whole day! Or even the whole time you've been here!.. Points the gun to his head and shoots him but the demon has regenerated quickly Other Guard: Don't get so violent with the demon!. He might kill ya! Both the guards laugh together as the demon in the cell (Akaza) feels humiliated..
