Background / History

Arthur is the heir of the borderlands’ Sun Family, a Grand Duke’s house with a long military tradition. His father, Grand Duke Annan Sunny, is the borderlands’ sole Seventh-tier Knight and a Demigod. Arthur was given the divine title Radiant Lion Cub on the day of his birth and was raised to fulfill the family’s hope of producing a Radiant Holy See Pope. 33 34 37

Although trained in Holy Light knowledge, Arthur favors direct combat and the image of a knight wielding a large blade. His natural physique and martial instincts are considered genius-level; even Ashley Xien can reproduce his knightly movements after using a body-experience card. 34 43

Arthur travels to the Imperial Capital for the Saint Trial alongside Ansu Morningstar and Liszt Moon. After initially submitting a blank written exam, he earns a perfect score in a later examination by defeating the magic prodigy Ashley in a physical duel. 40 42 55

Appearance

Arthur is a tall, muscular young man with long brilliant-gold hair, golden eyes, and the imposing bearing of a highborn knight. He is commonly associated with golden robes, armor, sun-patterned alchemical trousers, and a large golden staff. 33 41 173

• Long, brilliant golden hair. 33
• Brilliant gold pupils. 173
• Strong, well-built physique and exceptional martial presence. 40 259
• Wears noble or high-grade magic robes with golden armor elements. 33 41
• His awakened Sun’s Fire creates fiery patterns across his torso and can manifest as “Little Yoko.” 313

Personality

Arthur is forthright, proud, and intensely confident in his identity as a Sun Knight. He values courage, resolve, honor, and loyalty to his companions, often declaring that borderlanders are never cowards. 41 59

His confidence is paired with unconventional judgment. He routinely interprets Holy Light, knightly honor, and practical magic in ways that embarrass allies and provoke officials, but his bizarre methods are usually rooted in a sincere desire to fight effectively or protect his friends. 55 142 259

Arthur fears his stern father more than any enemy. This fear becomes a personal obstacle, yet Annan later recognizes Arthur’s successful inheritance of the Sun Family bloodline and Ansu’s positive influence on him. 178 313
