Yu-Hon (ユホン Yuhon) was Soo-won's father and was one of the most successful generals known to Kouka Kingdom before his death. He was the first-born son of Emperor Joo-nam and was believed to become the heir to the throne, but he kept his position as head general of the army when his brother Il inherited the throne instead.
Ever since Yu-hon was young, he was courageous and intelligent. Yu-hon was a strong warrior who always led Kouka Kingdom's armies to victories in their wars, during his father, Emperor Joo-nam's reign.
Yu-hon believed priests who could threaten the emperor's power were a nuisance. Therefore, he drove priests (Ik-soo) from the castle. Yu-hon also deemed the legend of the four dragons as forbidden text, possibly due to his firm belief that emperors should have the utmost power.
