|First Appearance||Episode 1|
|Alter Ego||Dear Baby|
Yaya often acts immature for her age, such as having an enormous sweet tooth, a great soft spot for items like ribbons as well as tending to be hyperactive. Yaya wants to be a baby forever so her parents would give her more love than her younger brother. She is also a good ballerina, but also a rather clumsy one. Yaya's favorite things are cute and babyish.
Yaya appears to be a peach-skinned girl with brown eyes and orange hair that is tied into small pigtails with large red ribbons. Like the other female Guardians, she wears a red cape at school.
As Dear Baby, Yaya's attire resembles of a pink baby rabbit, which is identical to Pepe, including a bunny hat, a yellow bib, and a set of slippers.Guardian Character is the infant-like Pepe, born from her desire to become a baby again.
Yaya gets a baby bib and a rattle as primary weapon, which can grow to massive size and can be used to perform "Giant Rattle Attack". The attack often ends up failing. In a later episode, she receives a bottle used to perform the "Milk Beam, Strawberry Flavor" attack. Coincidentally, both Yaya and Pepe become very immature during the change. To Character Change, Pepe says "Cutie, Sweetie, Love Baby!"
During Character Transformation with Pepe, she becomes "Dear Baby". This represents her desire to be babyish and get attention.
