Also referred to as Emperor Dayan, he is the ruler of Dayan Kingdom. He ascended the throne at age 12, took power at 18, and eliminated the regent at 25. He is 28 years old and known for his composure, but the series of supernatural thefts and the loss of his private treasury caused him to faint from shock. He was tricked by the Prime Minister into marrying the wrong daughter and discovered his half-brother King Yu colluded with enemy troops.
