This project marked a significant shift. REIRIE’s musical output and visual identity are far removed from the more mature, sometimes controversial, image-based work of the junior idol days.

In January, they celebrated the release of their major 1st EP, signaling a new, more professionally managed phase of her career.

As Rei looked back on her journey, she acknowledged the lessons learned, the friendships made, and the unforgettable experiences she had.

Despite the global success of Ladybaby, the manufactured nature of the idol industry continued to clash with Kuromiya’s evolving personal identity.

In 2021, Kuromiya added the title of "author" to her resume by releasing her first photo essay, titled "私が居なきゃ生きていけないって言ったんだから一生かけて証明してみせてよね" (Roughly: "Since You Said You Can't Live Without Me, Now Spend Your Whole Life Proving It"). The book was a major step for her, allowing her to openly discuss the complexities of her junior idol years, her feelings of being judged on her appearance, and her journey to find an authentic sense of self. This shift from subject to author reflects a key part of her evolution: reclaiming her own narrative.

Free from the constraints of the idol label, Kuromiya turned her full attention back to rock music, transitioning into a respected alt-rock frontwoman.

Reviewers often note her expressionless gaze and the "pain" visible in her early work, contrasting with the forced cheerfulness usually required of idols.
