Sword Maiden was an adventurer captured by goblins on her first adventure and tortured mercilessly. Yet, she somehow escaped and worked as an appraiser in Fortress City until the events of Goblin Slayer Side Story II: Dai Katana where she began work as an adventurer once again.

She made her mark in history ten years ago by defeating the Demon Lord along with five other adventurers, becoming a renowned hero. It was around that time that she first met the future King.
