- "Vamos de fiesta!"— Elena Bello
Elena Bello (ベッロエレナ Berro Erena?) is considered the lead Cure of Festival Pretty Cure!. Elena is an outgoing girl who loves to celebrate. Since she loves painting, she isn't the best student. Her and Sofia have been best friends since they were 5. Now that they're Cures, Elena sees a different side of them. Elena's become more confident and cheerful, knowing that Sofia will always be by her side. Her alter ego is Cure Fiesta (キュアフィエスタ Kyua Fiesuta?) and her standard theme color is blue. She is represented by circles. Cure Fiesta has two form changes, the purple Grape Jazz (グレープジャズ Gurēpu Jazu?) and the green Lime Electro (ライムエレクトロ Raimu Erekutoro?).
Elena's catchphrase is Vamos de fiesta! (バモスデフィエスタ！ Bamosu de Fiesuta!?), which means Let's party! in Spanish.
