Not all of the rituals demanded a sacrifice as large as the one Ash had to make for the sake of gaining what she did.
Ash had to sacrifice those of her bloodline, but there were no real specifics mentioned about what the limit was to how much she would have to sacrifice.
It was just written that she had to sacrifice those of her closest bloodline and sever her familial bonds for good.
She had done that by sacrificing the family that was connected to her by blood, but those who were sacrificed were her auntie, uncle and any others who were a part of her family who she had known to be remaining during that time.
The ritual had worked, but if it had demanded more of her, then it would probably not end with just that.
It seemed to work by severing the bloodline of her cousins, auntie, uncle and anyone else who was in the household, but not all of them were connected by blood to her, so it was doubtful if their involvement had contributed to the ritual in any way.
