I, however do not believe this. I believe this is just another urban legend trying to take away the innocence from a character. Another legend is that Hello Kitty didn’t have mouth on purpose, that her not having a mouth would represent children who were or are abused. Because in most cases most children would say anything about being abused and keep it to themselves.
I don’t believe that Hello Kitty’s “image” is supposed to represent any of this. A lot of these rumors were created by the ones who actually worship devil, and just want to frighten everyone who is a fan of Hello Kitty. But Hello kitty is really just and cute and innocent kitten who was created by an innocent artist. A lot of people would just assume these rumors are true, just like any other rumor out there. Hello Kitty is just another innocent character from Sanrio!
