The Crystal Princess is Prince Lionheart’s sister. But she is not just a purely decorative princess. The Crystal Princess is amongst the kingdom’s most talented fencers. In fact, she is so talented that she had her own sword and shield made. If there is fencing training in the castle courtyard or a knights’ tournament in the forest, you can be sure that the Crystal Princess is there. If there isn’t anything going on around the Crystal Princess, then she always makes sure to get things started.
