Similar to classic Princess Maker tradition, Yucie was found as an infant by the knight Gunbard after a battle, and became his adopted daughter. Due to an unknown curse, she stopped growing at the age of ten, and looks like a child despite the fact that she is now seventeen. Yucie is very cheerful and gregarious, but she has a very strong desire to break her curse and become an adult. One of the reasons is that she oftens feels that being small in size is a hinder to others, thus wishing to grow up.
