Everyone should know already that the image of Momo is just a Japanese statue, but it actually represent the image of a Youkai called Ubumetori.
I like that there is indeed someone unknown besides all the copycats, who registers Momo accounts and numbers in all countries which use WhatsApp.
Just as if a person wants to bring her back by manipulating modern society and tries to get faith for a being like her. Which afterwards will give the youkai itself the power to manifest in our world as a mass tulpa on the superspectrum.
