... i really suck at analyzing the story. Is the shadow world just like a game world where its not real or theyre really going to real places where these people cam actually go with them.

From what I understand the shadow world is a parallel universe that opens in the world, kinda like a mirage of the past that went wrong and converges with the present through the shadows that eats away the world so that's why is such a dangerous thing leave it like that, I'm not to sure why but they appear like persons in that world, is kinda like a simulation world where they need to solve the problems in order to make the history go right, but is just a simulation so is not like they change the past
This is adorable
