The Supreme Tablet
A carefree boy, chilling on his stone bed while enjoying his fruit juice mixed with crushed candy ruby, suddenly experienced the horror of his life as he watched the invasion of their clan, got enslaved, transformed into Metallic Hound and forced to serve for 21 years in perpetual agony.
He suddenly woke up and found that it was a nightmare dream he had just lived. However, before he rejoiced, he came to understand that not everything was as it seemed.
