Did you ever get sick for no reason when you were a child? No matter how much injections and medicines are taken, it can't be cured?
I often did this when I was a child, and then my mother took me on a bicycle to find the "God Mother" in a certain village. After being touched on the head by "God Mother" or something else (I didn't drink paper ash, absolutely not), I was fine (it seemed like promoting feudal superstition).
So, the story unfolds with this as the background!
The story of a high school girl who awakens her spiritual power and her guardian.
