Once Huntrix was defeated for good, Gwi-Ma was powered by the human souls enough to create a physical body for himself. The Saja Boys and other demons were all there when it happened. The demon king was taller than any other demon, standing at nearly seven feet tall with slightly tan skin, the purple demon patterns dancing across his skin. His hair was pitch black, his eyes a mixed pink and purple to match his flames. (This is just how I think he'd look (ノ◕ヮ◕)ノ.✧)*
Though the Saja Boys quickly realised something. Gwi-Ma had never had a body before. They were essentially working with a baby with the intelligence and attitude of a god.
After teaching the king how to walk properly, Baby realised something else and grinned.
Next thing you know, the Saja Boys were guiding Gwi-Ma through the streets of Korea, visiting every vendor they saw and having him try nearly every food they could find.
Gwi-Ma, experiencing the sensation of taste for the first time, looked fascinated.
