Clay S. Anderson hails from the noble family of the Knight Troop of the Ronza Kingdom and leads a group of adventurers. His grandfather was the legendary Blue Knight, and Clay embodies a similar legacy of honor, responsibility, and strong morals. He wields a gleaming longsword inherited from his ancestors, which he cherishes above all but his own life, maintaining it in flawless condition.

Though driven by a powerful sense of justice, Clay is not an aggressive combatant. His courage and loyalty are vital to the group's achievements. He shares a childhood bond with fellow adventurer Trapp, who comes from a bandit lineage. Clay's leadership and unwavering principles steer the group through diverse trials, from treasure hunts and riddle-solving to locating the missing.
