[Original Manga](https://booklive.jp/product/index/title_id/1792267/vol_no/001)
The contents are, first of all, "Possessed spirits", then the familiar "Mechanism of the invisible world" (with a nude illustration of a woman showing the body, aura, astral body, and spiritual body), and of course, next comes the excitement of "In the near future, the spiritual world and the material world will become one, and great changes will occur", and the last is "The work of fire". I thought I had absorbed some knowledge from the manga, but from the fourth chapter, which deals with "the mechanism of the invisible world", there were many sentences that were difficult to understand, and I was completely confused. I feel embarrassed because I didn't study hard enough.
