I'm not sure but I think he's his brother? Cousin? Yeah. From what I remember, the ml had to step down from the candidates for the emperor by the orders of the previous emperor or someone similar in power and he made him the duke so that there would be no blood shed in the palace and the ml was okey with it because he is a carefree and loose man infront of the nobles. There is also a crown/first prince, I think? Dunno but the current emperor in Yuder's previous life is also a prince or something in his second life and Yuder helped him to rise to the position he was in. I'm sorry, I also doesn't remember clearly but I think what I just mentioned is right, you're free to correct me if I'm wrong
Kishiar is the brother of the emperor, and a former prince. He was given the title of Duke of Peletta, thus no longer a prince, and Emperor Keilusa inherited the throne.
There’s a lot more to the story, and why that happened, but I won’t spoil that haha. The novel is about 1450 chapters ahead of this webtoon. Webtoon only readers are in for a longggg (but amazing!) ride lmao.
Can someone please help explain the character relationships in the royal family? Idk if i missed it or forgot but I'm getting confised how kishair is related to the emperor and who's in the royal family lol
