It is said that it was introduced in the form of autobiography, introducing his previous life to readers from the perspective of the protagonist, but in fact, most of the stories are very warm and timid. You can also see that the protagonist was naughty when he was a child. His parents thought he was a kid and invited him to exorcise ghosts. Then the rebellious protagonist can't stand this and runs away from home directly, meeting his master on the train.

The story in this book is similar to those evil things you may have heard from around, and the protagonist can't do any magic. The method he used is similar to that in folklore, not so magical.
