Information:
Yukionna never knew who her real family was, the one that took her in was her master of the Ice breathing. Thus named her after the demon of snow. She quickly learned the breathing technique and became strong.

The Ice breathing is known for one of the strongest breathing techniques and not everyone can use it since it takes a lot of power. So her mastering the breathing technique even from a young age is amazing.
