Not her, but her boyfriend who is to be summoned as a "hero" 200 years later. She and Rudeus were just caught in by accident because the miko of time, the one responsible for the summoning, lost control in her despair and they were in the vicinity of the hero at the time of the transportation. Rudeus was already dead and his only his soul was dragged in, that is also the best theory for him having arrived first, since he was only a soul with no body.
