Description
Jae Eun is a fictional character from the Pretty Rhythm franchise, specifically debuting in Pretty Rhythm: Dear My Future as the youngest member of the Korean idol unit PURETTY, alongside Hye-in, So-min, Shi-yoon, and Chae-kyoung. She is a 13-year-old middle school student who travels from South Korea to Japan as an international student, enrolling at Pretty Top Dance School to master the art of Prism Shows. She is also featured in ensemble idol performances within the movie Pretty Rhythm All Star Selection: Prism Show Best Ten.

Jae Eun has a distinctive appearance, with light pink hair, usually styled in braids or worn naturally wavy across her left shoulder and secured with a black barrette, and light brown eyes. She stands 161 cm tall. Her personality blends sweetness and honesty with a naturally airheaded disposition and noticeable clumsiness. She can also display selfish tendencies and is frequently portrayed as a crybaby. Jae Eun falls in love very easily, often developing instant crushes on boys she finds handsome, though these affections are typically fleeting and shift from one person to another. One of her most distinctive habits is tasting the sun while lying on grassy plains to gauge the day's atmosphere and recharge her energy, frequently using the catchphrase Paku-Paku (or Munch munch!) in her speech.

Within the story, Jae Eun's primary motivation is to grow as a Prism Star alongside her friends. She participates in Symphonia Series tournaments, where Prism Shows combine fashion, song, dance, and figure skating. Her closest relationship is with Reina Miyama from the rival unit Prizmmy, whom she considers her best friend. Their bond forms when Jae Eun invites Reina to join her in munching sunlight, but it faces tension when both develop feelings for a boy named Itsuki Harune. Jae Eun asks Reina to write a love letter to Itsuki, unaware of Reinas own feelings, leading to a conflict resolved when Jae Eun apologizes after shifting her affections to another boy she calls her Knight. She also develops crushes on Shou and later on a chef named Ken Shiotani, whom she supports in his relationship with his childhood friend Kurumi by performing in a Prism Show where he proposes.

During the Symphonia Selection: Road to Symphonia tournament, Jae Eun is grouped into a unit called Sprouts with Reina and Ayami. Though she is the only PURETTY member in the group, she enjoys collaborating with her teammates as Sprouts places fifth in the competition. In later episodes, after team shuffles end, she returns to PURETTY. Notably, Jae Eun is the only PURETTY member who never holds the center position in performances. Her narrative arc highlights a gradual maturation, evolving from a self-centered crybaby to someone who supports others relationships and team goals, even amidst her many fleeting romantic interests. In the finale of Dear My Future, she returns to Korea with her PURETTY colleagues, parting tearfully from Prizmmy at the airport before reuniting with them later while performing Prism Shows in Korea. As a Prism Star, her theme color is rose pink and her fashion type is Lovely, making her the only Lovely type owner among the main protagonists of the work.
