Kristen is known as the 'Undying Knight,' a relentless admirer of Saintess Theresa. He hunted Talli three times, each attempt ending in her near-death. During the third encounter, Talli managed to strike him with the Fred family crest, wounding his forehead and shattering his legs. He is described as having a firm will and great strength, far surpassing that of Carl Fred. His identity is concealed by plain clothes, and his forehead wound made his features unrecognizable.
