Not much is known about God's Gift's sister, other than she is the older sibling and died in sacrifice of her brother and that this happened on her wedding day. Neither is it ever mentioned of who she'd marry. As for her appearance; there is for only an instant, an image of her, who is most likely the girl who appears with a red scarf. She has white/silver hair, wearing a red scarf around her neck and what appears to be a poncho, resting on her shoudlers. She wears a white jacket, similar to a labcoat, moreover, the cuff of her shirt is black-alike to the school uniform God's Gift wears. This suggests that she was in fact, wearing school uniform-and this was showing a scene before the wedding disaster.
