UPDATE: So, the user who originally posted the story came clean on the Toho Kingdom forums and announced that it was made up. We've gotten a lot of flak for posting the rumor to begin with, but I personally love fake rumors like this one when it's obvious that someone put a lot of effort into it. The story they laid out was incredibly interesting and they went the extra mile to include details that sound like they would be plausible coming from the filmmakers involved and their previous works.
Kudos to the user JetJaguarPaunch, and I hope everyone arguing about this can just take a deep breath and enjoy these next few months when we truly don't know anything about Toho's new film and can get this excited about the many possibilities the movie has in store for us. What follows is the confession to making up the rumor posted a few minutes ago on the Toho Kingdom forums and our original article on the rumors.
