Male. 24 years old. Height 185cm. The First Prince and Crown Prince of the Calphon Kingdom. He has long black hair in a ponytail and citrine-yellow eyes with dark circles.

However, there's a reason he was chosen as Crown Prince, though he collapses onto his bed the moment he enters his room. In reality, he is a lethargic Crown Prince. He has a wolf-like, blunt personality. He's only like that because everything is a bother, but that personality actually makes him popular among the young ladies. He ignores all marriage proposals.
