[8] Nibu served as a title song center (lead performer) for the first time for Hinatazaka46's ninth single "One Choice", released on April 19, 2023.

[9][10][a] On August 6, 2024, Nibu announced that she would leave Hinatazaka46 after the promotions for the twelfth single, to be released on September 18, have concluded, citing persistent lower back pain as the reason.

[14] Nibu and fellow Hinatazaka46 members Miku Kanemura and Miho Watanabe were voice actresses for the animated miniseries adaptation of the character Pickles the Frog, aired in October 2020.

[16] Despite her inexperience, executive director Junichi Fujisaku remarked that he treated her "equally" to the other voice actors,[17] while co-star Ayana Taketatsu commented that her performance did not "feel like that of a first-timer".

[23] Nibu's first two live-action feature films are the 2024 Shinji Muroi duology, continuations of the long-running Bayside Shakedown detective series.

Producer Chihiro Kameyama and screenwriter Ryoichi Kimizuka considered casting her after watching her appearances on a video gaming television show, while director Katsuyuki Motohiro remarked that her experience as an idol contributed to her "nuanced" performance and ability to respond well to his "interesting" direction.
