Shirayuki

POLAR BEAR PRINCESS

She pulled the impossible sword from the stone, however its massive height and weight otherwise are a little too much for her to hold. 

With meager magic she manages to float it as she travels along, but due to her inability to take it very far, she winds up crying a lot out of frustration. 

Her goal is to be a warrior -- a knight, in particular -- but her family has other plans.
