Xero is a prince but he hates the royal life. He rarely spends a full day in the castle. He's more casual than he is formal even though royals are supposed to be formal at all times. Despite being the heir to the throne, he ignores his expectations and responsibilities. He’s playful and loves teasing the girls in kingdom. He will soon find out that he was gay all along and fell for a stunning male siren the second he laid eyes on it.

As the king of Avernia and Xero’s father, he is thoroughly exhausted and tired of trying to get his son to be more responsible as the heir to the throne. He is very controlling but also understanding. He is usually kind and rarely raises his voice. When he does get angry, he can throw a huge tantrum and sometimes even throw furniture.
