After meeting Kyle Dunamis and his companions by chance, the group is astounded to discover that Harold is the Harold Berselius, the creator of the Swordians, as everyone assumed the famous historical figure was a man rather than a woman. Harold claims to have intentionally used a man's name to "fool historians", acknowledging that her birth name is different. Due to the distorted timeline in which she lives, Barbatos Goetia, who should have been dead, is alive and disrupting the plans of the Radisrol team to attack Dycroft, thus without Kyle and the other's intervention. This series of events would have instead led to the war being won by Dycroft, with Barbatos being written in history as a hero. Not at all surprised that Kyle and his companions are from the future, Harold recruits them in assisting her with the preparations of Radrisol's historically significant attack on Dycroft.
