As has already been announced, Miki's LP music is Rome and Marco Polo.
And according to the following post, the character she will portray is Cleopatra !!
I found this post by Akira Andrea in the FSU forum
" Miki Ando who is the third place of 2009 Worlds declared that she becomes completely to Cleopatra in the free skating of this season. She said, “She has the forceful image ruling a country, has the strong feelings, too, as one woman before that and falls in love also. I wish I could express the outlook on life.” As for a point in common with Cleopatra, she made everybody laugh with saying "Will it be a black hair?". "
Miki is very exotic. I think it's a great choice. Miki Cleopatra !!
