**Hometown:** Kouchi
**Height:** 130 cm

Absent-minded and innocent, Kozue is a young child recruited by the producer that resembles a fairy. Naturally inquisitive, it is hinted that Kozue has lived a sheltered life until the start of her idol career. Always drowsy, Kozue tends to doze off frequently and in her lines tends to elongate end vowels and speaks entirely in hiragana.

In the tie-in Cinderella Girls Theater strips, Kozue is shown to have a sister-like relationship with Aya Kirino. Despite not sharing many things in common, Kozue and Aya bonded over Aya's secret hobby of doll collecting. This duo is known as Yousei and Onee-san. 

The U149 in the title refers to the aspiring idols at the center of it all: These small girls are ready to make it big! All under 149 centimeters tall, this group of aspiring pop idols dream of performing for thousands of people. But with zero experience, they’ve got a lot of work to do. Not to mention there’s a distractingly cute prince in town! With the help of their rookie producer, who’s just as short, can they stay focused and make it to the top?
