Description
Jae Eun is a 13-year-old South Korean student at Japan's Pretty Top Dance School. She has light pink, medium-length wavy hair, often styled across her left shoulder and secured with a black barrette, light brown eyes, and stands 161 cm tall. As the youngest member of her study abroad group, she debuts in the Prism Star group PURETTY and later participates in the unit Sprouts during team shuffles.

Her personality is sweet, honest, and naturally airheaded, marked by notable clumsiness. She frequently uses the catchphrase "Paku-paku" while pretending to eat sunlight to "recharge" her energy and assess her daily mood based on the sun's colors. Possessing a wide imagination, she falls in and out of love easily, often developing instant crushes on boys she finds handsome.

Her story begins when she meets Reina Miyama while lying on grass and "munching" sunlight in Episode 5. They quickly become friends, but their relationship faces tension when both develop feelings for Itsuki Harune. Jae Eun asks Reina to write a love letter to Itsuki, unaware of Reina's own feelings, leading to a conflict resolved when Jae Eun apologizes after shifting her affections to another boy she calls her "Knight."

She joins PURETTY's debut after a training camp. Her affections shift again to Shou in Episode 20. She participates in group activities like a scavenger hunt on a cruise ship and helps revive a restaurant after developing a crush on its chef, Ken Shiotani, in Episode 33. Upon learning he loves his childhood friend Kurumi, she supports him by performing in a Prism Show where he proposes to Kurumi.

During team reshuffles, she is grouped into Sprouts with Reina and Ayami for the Symphonia Selection: Road to Symphonia tournament. Sprouts places fifth; Jae Eun enjoys collaborating with them despite being PURETTY's only member in the unit. Her professional journey includes performances in coordinated outfits like the PURETTY Prism Show coord, Sprouts' butler-themed attire, and seasonal event wear such as a Halloween witch costume.

Jae Eun is the only PURETTY member never to hold the center position in performances. Her narrative arc highlights her gradual maturation, evolving from a self-centered crybaby to someone who supports others' relationships and team goals, even amidst fleeting romantic interests.
