Early Life and Background
Rei was born Naoi Rei on February 3, 2004, in Japan. She joined Starship Entertainment as a trainee ahead of IVE’s formation, becoming one of the members revealed to the public during the group’s staggered pre-debut reveal period in November 2021.
Career Highlights
Debut and IVE’s Formation Rei officially debuted as rapper and vocalist of IVE on December 1, 2021, with the single album Eleven. The title track’s music video drew 45 million views within days of release, and IVE earned their first music show win just seven days after debut — an extraordinarily fast start for a rookie group.
A String of Genre-Defining Hits Rei’s rap verses became a defining feature of IVE’s rapid string of hits, including “Love Dive” (April 2022), which won Song of the Year at both the 2022 MAMA Awards and Melon Music Awards, and “After Like” (August 2022), which sold 1.7 million albums overall.
She continued contributing to the group’s subsequent releases, including I’ve Mine (2023), Ive Switch (2024), Alive (2024), Be Alright (2025), and Ive Secret (2025), led by the single “XOXZ.”
Growing Individual Recognition Rei’s individual profile expanded considerably through 2025. On May 29, she served as a host at the Asia Star Entertainer Awards, marking the first time she’d hosted a major awards ceremony.
On October 5, she attended the Valentino Spring/Summer 2026 fashion show during Paris Fashion Week alongside fellow IVE member Liz. Just ten days later, on October 15, she won the “Best Trend Leader” award at the TikTok Awards Korea 2025, recognition tied to her participation in a viral TikTok challenge promoting IVE’s song “Attitude.”
In November 2025, she released a cover of the song “Baby Powder,” filmed in Paris during the same European schedule that included her Valentino fashion show appearance.
Continued Group Activities IVE performed at Lollapalooza in 2024 and embarked on their first world tour that same year, with Rei’s individual profile continuing to grow alongside the group’s collective momentum.
In late February 2026, IVE returned with a highly anticipated full-length album comeback that Korean media described as “the return of K-pop queens.”
Personality and Public Image
Rei has developed a reputation as one of IVE’s most fashion-forward and trend-savvy members, reflected in her rapid rise across hosting, high fashion, and viral social media recognition through 2025.
During lighter press moments, she’s shown a playful, self-care-conscious side, joking about wanting a Vaseline face mask treatment — a trending skincare method in South Korea — during interviews discussing the group’s self-care routines.
Her growing individual visibility, particularly her Paris Fashion Week appearances and her TikTok trend recognition, reflects a rising public profile that’s developed alongside her core role in IVE.
That rapid string of milestones within a single year — from her first hosting gig in May to a major European fashion show in October and a viral trend award just days later — has made 2025 something of a breakout stretch for Rei specifically, even within a group already accustomed to constant achievement.
Fans have noted that her comfort moving between these very different spheres, from formal awards-show hosting to spontaneous TikTok content, reflects a genuine versatility that sets her apart even among her similarly accomplished groupmates.
Her status as IVE’s sole Japanese member has also made her a particularly significant figure for the group’s fanbase in Japan.
