Titles like "Rei-chan no Oshaburi" (Rei-chan's Pacifier) and "Shiroi Mizugi no Rei" (Rei in a White Swimsuit) became collectors' items. Her popularity was driven by a "girl-next-door" authenticity. In interviews and behind-the-scenes footage, she came across as cheerful and playful, which fans found "healing" (iyashi)—a core selling point of the genre.

Following her departure from LADYBABY, Kuromiya refocused her energy entirely on BRATS, the band she had founded as a child. In the years following, BRATS evolved into a more mature act, releasing several music videos, including the song "Nounai Shoukyo Game" ("Brain Erase Game"), which was used as the theme song for the 2017 film Slaveman . They also contributed the opening theme "Ainikoiyo" for the anime series To Be Hero in 2016. For a time, it seemed that the band, now featuring the grown-up Kuromiya sisters, was building momentum. However, the group’s history was plagued by instability. On March 31, 2024, Rei and Aya Kuromiya jointly announced that BRATS would be placed on an "indefinite hiatus." The announcement on their official website explained that their contracts with their management and record label had ended, and the duo decided to step back from the project. While the statement left the door open for a possible reunion in the future, it effectively brought an end to the musical vehicle that had been a constant in Kuromiya’s life since she was a preteen.
