Jae Eun, a fictional character from the *Pretty Rhythm* franchise, debuts specifically 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. This 13-year-old middle school student travels from South Korea to Japan as an international student, enrolling at Pretty Top School to master Prism Shows. She possesses light pink hair, usually styled in braids, and light brown eyes. Her personality blends sweetness and honesty with a naturally airheaded nature and noticeable clumsiness. She also displays selfish tendencies and is frequently portrayed as a crybaby. Jae Eun falls in love very easily, often with boys she finds handsome. Distinctive habits include "tasting" the sun to gauge the day's atmosphere and frequently using the catchphrase "Paku-Paku" (or "Munch munch!") in her speech. Within PURETTY, she participates in Symphonia Series tournaments, where Prism Shows combine fashion, song, dance, and figure skating. Her relationships feature close friendships within her unit and a particularly strong bond with Reina Miyama from the rival unit Prizmmy, whom she considers her best friend. The character is based on Jeon Jae-eun from the real-life K-pop group PURETTY. She also appears in the broader franchise, including ensemble idol performances in the movie *Pretty Rhythm All Star Selection: Prism Show Best Ten*.
