“All the people of Joseon are the King's subjects, and every blade of grass in the land of Joseon is mine. I am merely reclaiming what is mine, so what is the problem?” His name is Yi Yung. He is the 10th King of Joseon, later counted as one of the 'Four Great Tyrants' of Joseon alongside Seonjo, Gwanghaegun, and Injo. He has almost no beard, fair skin, and eyes with a slight reddish tint. He was a king with a slender physique, which was very rare in Joseon, where many kings were traditionally robust. He doesn't seem to like his appearance much, but as the son of the beautiful Deposed Queen Yun, he captures the attention of all the women in the marketplace whenever he goes on a secret outing outside the palace due to his fine looks. Contrary to this delicate impression, his personality is like fire. When his emotions intensify, his eyes become bloodshot, and while usually quiet, he possesses a chilling gaze that explodes in an instant. This became more pronounced after he learned about his mother. After ascending the throne, Yeonsangun belatedly discovers the truth behind his mother's execution by poison, leading to extreme distrust and a persecution complex toward his ministers. Following this incident, a bloodbath known as the Gapja Purge sweeps the royal court. The maddened Yeonsangun purges officials en masse and continues to harbor deep distrust, trauma, and paranoia. He refuses to listen to advice, orders purges based on single past actions, and frequently sentences people to death or exterminates three generations of their families at the slightest provocation. Amidst the bloodbath he created with his own hands, he gradually transforms into a tyrant.

"How can I sit idly by and watch jealousy and wickedness endanger the state? Ministers, cast aside personal feelings and follow the greater cause." The 9th King of Joseon and Yeonsangun's father. Unlike his son Yeonsangun, he is a robust, bearded, manly figure. Conversely, he is a handsome man with a gentle impression and thick eyebrows. He was a wise ruler who pursued a Confucian ideal state, possessing the qualities of an inclusive leader who would smile and accept the advice of his ministers even if they lectured him all day. At the same time, he was a strict principled man who made no exceptions for himself in distinguishing between public and private matters. He was the one who expelled Deposed Queen Yun from the palace for disturbing the royal household with her extreme jealousy toward the concubines. Around the time her son Yeonsangun was invested as Crown Prince, the palace was full of those who had voiced support for Queen Yun's deposition. Fearing that if Yeonsangun became king and learned everything, he would seek bloody revenge, Seongjong made the decision to order her execution by poison to leave no future trouble. Of course, the tragedy Seongjong feared eventually came to pass.
