User blog:Ryurider 76/Parallel Universe

A parallel universe, also known as a parallel dimension, alternate universe or alternate reality, is a hypothetical self-contained plane of existence, co-existing with one's own. The sum of all potential parallel universes that constitute reality is often called a “multiverse". While the three terms are generally synonymous and can be used interchangeably in most cases, there is sometimes an additional connotation implied with the term "alternate universe/reality" which implies that the reality is a variant of our own, with some overlap with the similarly-named alternate history. The term "parallel universe" is more general, without implying a relationship, or lack of relationship, with our own universe. A universe where the very laws of nature are different – for example, one in which there are no Laws of Motion – would in general count as a parallel universe but not an alternative reality and a concept between both fantasy world and earth.

Wouldn't it be really cool if there were Parallel Universe's shown/seen in Kagerou Daze series and that there was some kind of way to travel between them somehow? Because I think that would be so cool and awesome and if it happens the Mekakushi Dan should do that somehow for some reason maybe even meet alternate versions of themselves from alternate universe's.
