The world of witches has broken down geographical distances thousands of years ago, and the Witches of the East are the most mysterious group among them. They possess powerful magic power, but they remain low-key in the worlds of humans and witches. Very few humans can capture information about them.
Witches of the East have always liked to be solitary. They hide their tracks to prevent being discovered by humans or witches.
We have no way of counting how many witches of the East exist in China and City A, and no one knows. Maybe there is a master of magic—a witch—around you.
