Miko, that is, the daughter of witches, is the offspring of the union of witches and ordinary people. After thousands of years of time, the witchcraft nature of each generation of witches will become weaker and weaker until they disappear.
However, everything eventually changes. "Mo", the offspring of a witch with only 1/16 witch blood and an ordinary man, showed amazing witchcraft when she was 10 years old.
Her amazingly pure witch nature makes her no longer an ordinary witch, but slowly transforms into a real witch.
Whether it was luck or misfortune, only she knew. But living dozens of times longer than a mortal is enough to make her and her experiences a legend.
