Okay, in the first episode of Mahou Tsukai, Yuki Kanoko, Mirai's grandmother, looked away when her daughter asked where the pendant that had Mirai's Linkle Stone Dia in it came from, almost like she knew, but didn't want to answer.

And in episode three, after she heard Mirai's story, she simply agreed. I'm pretty sure most people from No Magic World would have responded with something like, "Wait, what did you just say?"

So basically, I think she might originally have come from Magic World. That would certainly explain a lot!
