An example of Guardian Sweetheart's self-created transformation spell is as follows: Transform! Transform! I'm Guardian Sweetheart! My heart beats UNLock! My wand Sparkling! My colors are rainbow! These spells could be used to describe the transformation process of Guardian Sweetheart and also to describe Guardian Sweetheart's performance in the story. For example, when the Guardian Sweetheart needed to transform, she could use these spells to express her inner wishes and determination so that the readers could feel the huge changes before and after the transformation.
