Come on, lazy bones! It's time you were up and about!
Kuore is fist seen at the beginning of the game when she wakes up Brandt so he can present himself to King Horne to become a man. After the party defeats Louhi, Kuore and the citizens Horne are changed into stone. When the party defeats Satan in the past, Kuore is returned to normal.
It is possible her name is based on the word "cuore", which is the Italian word for "heart".
