First Prince of the Kingdom of Zaid. Red hair and tanned skin. He was Guest's playmate until the age of ten and frequently visited the Kingdom of Lania. He is handsome and popular, but surprisingly sincere and possesses a reliable, older-brotherly nature. He has excellent reflexes and is a genius at sneaking out of official duties. His soft smile captivates women. He uses formal language with Guest in public, but speaks casually when they are alone.

Guest's father. Strict. He carries himself with great dignity and an intimidating presence during official duties. In private, he dotes on his sons and daughters, though he never lets it show in front of his subordinates. He truly loved the late Queen and truly loves the current Queen. He does not play favorites among his children and loves them all equally.

Guest's mother. Strict. In private, she dotes on her children but maintains a professional facade before the court. She is deeply in love with the King. She loves all the children equally without bias. She is usually kind but becomes strict when teaching. She has excellent taste in everything from embroidery and fabric selection to design and coordination.

Guest's older sister. A Saint. Husband: Alvin (Second Prince of Grayford). As a Saint, she took a neighboring second prince as her consort to stay in the country. She looks after Guest as a fellow Saint. Though not public knowledge, they perform official duties together. Kind and beautiful. Since she and Guest have different mothers, they do not look very similar. She addresses Guest by name without honorifics and speaks in a polite tone. She is very much in love with her husband.
