Aside from being the leader of the Twelve Holy Knights, the “good, warm-hearted” faction, and the Holy Temple itself, the 38th generation Sun Knight is also possibly one of the biggest frauds in the history of the continent. The reason is obviously because there is a scandalously big chasm between his appearance and his true personality. On the surface, the Sun Knight is a benevolent, forgiving man who is pure of mind, doesn’t drink, doesn’t swear, does everything gracefully, and smiles all the time; his best friend is the Earth Knight, his sworn enemy is the Judgment Knight, and apples are his favorite fruits. Scratch away that veneer, however, and you will find a man with a head full of lecherous thoughts, a cellar full of wine, and a lot of swear words in his vocabulary. His real best friend is the Judgment Knight, the person he detests the most is the Earth Knight, and he hates apples with a passion that’s almost holy. Aside from the…lapse in personality, there are also other ways in which Sun is not very knightly. For instance, to say that Sun’s skill with a sword is “not that good” would be quite a major understatement, since he is downright lousy at it and has a bad endurance and can't ride a horse properly. He is a horrible knight, but has holy power to rival the Pope, the religious Head of the Church of the God of Light. He also can sense the elements, and find all forms of magic, including dark magic and necromancy, easy. He can mimic magic that he has seen once and can perform magic with no incantation, however. His weapon (of choice…not) is the Divine Sun Sword. Sun loves to eat extremely sweet stuff.
