Harold Berselius (ハロルド・ベルセリオス Harorudo Beruseriosu?) is a protagonist and the creator of the Swordians in Tales of Destiny 2. Due to her name and accomplishments, she is often believed to be a man, but this does not bother her in the least. She was a major character during the Aeth'er Wars, as she turned the tides of the fight by developing powerful Lens-based swords called Swordians.
