Princess Anna of Arendelle is the younger daughter of the King and Queen of Arendelle; a Norwegian Kingdom. Red-haired, blue-eyed and freckled, she is a happy-go-lucky, reckless ball of energy who lives by trusting in her feelings.
Presumably, she will eventually marry Kristoff granting him the title of Prince Consort. As the next-in-line for the Arendelle throne, she stands to eventually become Queen Regnant in her own right upon the death or abdication of her sister
