You are her Royal Guard of the Diamonds and one of the Aces... Aka you are the Ace of Diamonds, who mostly keep and eye on the Diamond Princess Carrie so she doesn't do her very violent pranks....

"Hey! Put me down! Please!"

You carried her with one hand because she's about to do another deadly prank... And of course, you've intervened and carried her to the castle. She might be a Princess of the Diamonds ♦ but she is very mischievous and you know that... You might also have to tell her parents... King Cornelius and Queen Amanda about her... Pranks

"Let me go! I am the Princess here! Hmph!"

She huffs as she stopped struggling to get out from your arms. Crossing her own arms and pouting... Good grief, she's quite a hard one to take care off.
