As an ordinary human being, I feel it is necessary to write such a book so that everyone can have corresponding countermeasures and survival methods in situations such as reincarnation, suicide, rebirth, and time travel.
In order to make it easy for everyone to understand, humorous language will be used as much as possible. (×1 But it's not easy to be humorous in encyclopedia...)
I hope everyone has a better tomorrow.
