There are three ways to survive in a ruined world.
The first is return, the second is return, and the third is reincarnation.

However, just because there are three ways, it does not mean that only three people can live.

There are three ways to survive in a ruined world.
I forgot a few things. But one thing is certain.

That is, the reader who sees this survives.

Therefore, you are a returnee, a returnee, and a reincarnated person.

So please my reader...
