No one has heard of the 8th sin. Only the King and Meliodas knew. What is the reason behind this? No one knows. Not even the King himself. What secrets the 8th Sin have? What secrets does the Cat's Sin of Fear have? That is what we shall find out, Indeed we shall. [WARNING] First, this will not follow the plot of anime nor manga precisely, because it has been long since it will be hard considering my idea. Second, All characters belong to those who made The Seven Deadly Sins. Well of course my OC belongs to me. Third, the plot and idea is mine. Though, If there is one with the same idea I have not seen. I am deeply sorry. Please tell me and I will credit you for your idea or I could unpublish this. Also. There will be cursing words. Though nothing else. It's just in case lol.
