The Parent refers to the player in Tales of Phantasia: Narikiri Dungeon. In the game's remake, Tales of Phantasia: Narikiri Dungeon X, the Parent is replaced by Etos, who was given the twins by Norn prior to the events of the story.
The game's story begins with what appears to be a shooting star landing in the mountains. A narrator describes the player in second-person, having found twin babies, a boy and a girl, at the site of star's landing and becoming their adoptive parent. Their default names become Dio and Mell, while the Parent's name is never mentioned. The game's central plot begins thirteen years after this event, with Dio and Mell having developed their own unique personalities: Dio is energetic, while Mell is more level-headed.
