A girl named Reina always thought she was just your normal everyday high school girl. But one day, a somewhat familiar-looking blonde shows up at her front door and tells Reina that she is her sister AND the princess of Solaria! Reina's life was changed forever. She learned hard truths about her history and her family. She learned that with great powers, comes great responsibilities. And Reina also learned that she can't just poof up an unlimited supply of pancakes. At first, adjusting to this new life wasn't as difficult as Reina had anticipated. Everything was going just fine. That is, until an old threat to the Winx comes back again. But this time, they're after a new target.
