As it turns out, there is a timeline where humans come to Novanati, but not in the way anyone was ever expecting. When Ultimate Inventor Miu Iruma creates a device that can see into other dimensions, the last thing she expects is for the machine to unexpectedly go haywire thanks to her assistant, Kazuichi Souda, messing up some calculations during production. Because of this flaw, they find that all those close to them and themselves have been transported to an alien world where everything is different: the world of Novanati, where no Homo sapiens sapiens has ever set foot before. Now finding themselves the intruders on this land, they have to figure out how to survive here before figuring out how to get home. And that's just Arc 1 of the story!
