When I was watching Naruto, I thought the fictional dream world of Mugen Tsukuyomi was quite interesting, so I wrote something similar, but the story and Naruto are not actually related.
Here is an explanation of Infinite Tsukuyomi. Infinite Tsukuyomi probably allows people to fall into a false perfect world. To put it simply, it is a sweet dream.
This novel is about a few people saving the world.
For the rest, well, just read the article, I don't know how to write copy.
