As the lead vocalist, Rei traded the curated, compliant smile of an idol for raw, aggressive vocal deliveries. BRATS served as a creative outlet where she could vent the frustrations of her highly controlled teenage years. Music videos like "Misery" and "Unfair" showcased a darker, heavier side of J-rock, earning them international recognition and leading to a US debut at Anime Los Angeles.

During her career, Kuromiya appeared in various Japanese television dramas, such as "Shōjo Manga" (2003), "Kōkō Kyōshi" (2003), and "Yūko to Sora" (2004).

Rei Kuromiya (Japanese: 黒宮れい, Hepburn: Kuromiya Rei ) is a Japanese singer, musician, and former junior idol from Saitama Prefecture whose career represents one of the most complex and scrutinized trajectories in modern Japanese pop culture. Born on November 29, 2000, Kuromiya began her professional life in the entertainment industry at the astonishingly young age of eight, entering a world that would both shape her future and become a source of significant public debate. Her journey from a child gravure model to the frontwoman of a punk rock band, and later to a major-label recording artist, is a story of transformation, resilience, and, for many, a cautionary tale about the ethics of the junior idol industry.
Just as Western millennials obsess over 90s Nickelodeon or 2000s Disney Channel stars, Japanese otaku culture has entered a phase of intense nostalgia for the early Heisei era (2000s). Rei Kuromiya represents a specific aesthetic—the low-resolution video grain, the dated fashion (tube tops, side ponytails, flip phones), and the pre-social media innocence of early internet fandom. Finding her DVDs is akin to discovering a time capsule.
The LADYBABY lineup was short-lived. In late 2016, Ladybeard announced his departure from the group to pursue other projects. Rather than disband, Kuromiya and Kaneko chose to continue as a duo, rebranding as . The new formation adopted a darker, more mature musical direction, with Kuromiya taking on an even more prominent role as the lead vocalist. Their music became more grounded in alternative rock, moving away from the novelty metal of the trio era. However, this period was also marked by difficulty. In November 2017, Kuromiya made the difficult decision to leave the group, citing a worsening throat condition that made live performances increasingly painful and difficult. She issued a public apology to her fans, explaining that she had been forcing herself to continue performing and could no longer do so. This departure marked the end of her involvement with the LADYBABY project and a temporary pause in her career.
