Story for IT is by Mashima, so Mary is Mashima's character too.

What canon was broken? If you're talking about the rain thing ... it was never said that it never once stopped raining in her life. And, considering the fact that she returned to her life of being shunned, it wouldn't be hard to believe that she thought of that one incident as a daydream and forgot about it.

I don't think it's Mary because she looks to young. ._.
