Summary
At twelve years old, Yaya Yuiki is a somewhat immature girl who serves as the A-Chair, placing her a year junior to Amu. She has a fondness for sweets baked by Nadeshiko and sports her hair in pigtails secured by two large ribbons. Despite being a ballerina, she is notably clumsy and lacks the ability to swim. Yaya has a newborn baby brother named Tsubasa, whom she believes receives all of her parents' attention. This jealousy is reflected in her Guardian Character, Pepe, who appears as a baby for the same reason. During a Character Change, Yaya transforms into a baby who wields a giant rattle as a weapon. Influenced by this form, she adopts a crybaby personality, with Pepe chanting "Pretty, Cutie, Love Baby!" during the transformation.
