She started life as an egg carried under her sister’s arm until finally she hatched.
HIIAKA used to run errands for her big sister and one day was sent off to fetch a handsome prince for matrimonial purposes. The prince seemed willing enough to accompany her, but on the journey back they came under deadly demon attack.
The prince, being mortal, kept being killed and had to be re-constituted after each affray, with HIIAKA having to run around and catch his soul which kept turning into a butterfly, or smoke, or perfume. It was a very versatile soul and made the most of its freedom.
Meanwhile PELE fretted with impatience, and then jealousy, which finally erupted when the wayward couple appeared. She swamped them with volcanic lava which proved fatal to the prince.
HIIAKA reconstituted him for the last time, and decided they could not go on meeting like this. The prince, having experienced PELE in action, agreed. So they did a runner because they realized love was just around the corner. Or maybe a bit further, because PELE never found them.
