During her childhood, she understood the Fourth Holy Grail War about as much as Shirou understands the Fifth, seemingly understanding while not actually comprehending it. She saw her father as a great magus who must be respected and loved, but failed to understand the negative aspect of his personality, the coldheartedness that accompanied such an ideal. If he had lived until Rin could actually understand his personality, it is likely that it would have greatly affected the development of her own personality. It is unknown if she would have opposed such inhumanity and left the path of a magus, or if she would have become a “perfect and coldhearted” magus like her father. Either fate for Rin would have been one far away from happiness.[6] Due to Tokiomi's early and untimely death, she was not aware of the original goal of the Holy Grail War to open a “hole” beyond the World.[7]
