She is able to perceive and see things that others kids, around her, can not. She's a very gentle, docile and honest child, one could say almost carefree, since sometimes she seems to have trouble understanding other people's emotions, especially when they are aimed at her.
Sometimes she has visions, and they may or may not happen. Other times these visuals may scare her tremendously, which she needs to make extra mental effort to chase them away from her mind.
Her name seems to be a play of words with her peculiar ears(Mimi) and being loved by all around her, like a "princess"(Hime).
