Giselle

Who Is Giselle? aespa’s Multilingual Main Rapper

Giselle is the main rapper and sub-vocalist of aespa, and she’s one of the most unique idols in K-pop simply because of how fast she got here. Born Uchinaga Aeri on October 30, 2000, to a Korean mother and a Japanese father, Giselle grew up mostly in Tokyo, attending the prestigious International School of the Sacred Heart. She only trained at SM Entertainment for about 11 months before debuting — one of the shortest trainee periods in the company’s history.

A Fast Track to Debut

Giselle actually auditioned for SM Entertainment four times before she was accepted through the company’s tough Saturday open audition. Once she got in, things moved quickly. On November 17, 2020, she debuted as the fourth and final revealed member of aespa with the digital single “Black Mamba,” bringing sharp rap delivery and a distinctive, husky tone that instantly stood out.

The Group’s Language Bridge

Because she grew up fluent in Japanese, Korean, and English, Giselle often steps in as an informal translator during international interviews, helping aespa connect with fans around the world. She’s also known for writing her own rap lyrics — she even performed self-written verses during her SM audition, long before she was a trainee.

Going Solo

In October 2024, Giselle released her first solo track, “Dopamine,” as part of aespa’s special single SYNK: Parallel Line. The song let her show off her songwriting chops and rap ability outside the group format, further building her identity as an individual artist.

Personality and Fun Facts

Off stage, Giselle is known for her quick wit, sarcastic humor, and being the group’s self-described “mood maker.” She was in her school choir for four years as an alto, can play the guitar, and has openly shared that she has ADHD. Fans often compare her look to f(x)’s Krystal, and she’s become a favorite for brands like Loewe, which named her a brand ambassador in 2024.

From growing up between two countries to becoming one of aespa’s most versatile performers, Giselle represents exactly what makes fourth-generation K-pop so global — she’s proof that a multilingual idol with a short trainee period and a lot of talent can still make it to the very top.
