Mirai Tachibana is a Japanese voice actor and singer affiliated with the agency Music Ray'n. She was born in Chiba Prefecture on March 5, 2000. Tachibana decided to pursue a career in voice acting during her third year of high school, opting to attend a vocational school for voice actors rather than a university. During her high school years, she was the president of the drama club and also participated in choir competitions as a soloist.

In 2017, Tachibana participated in the third Music Ray'n Super Voice Actor Audition and was selected as a third-generation trainee. She took lessons for about a year and a half before making her professional debut in the winter of 2020. Her first credited anime role was providing voices for various minor characters, such as female students, in the series Jibaku Shonen Hanako-kun.

Tachibana's first major leading role came in 2021 when she was cast as Kotono Nagase in the multimedia idol project Idoly Pride. This project, which spanned an anime television series and a video game, significantly raised her public profile. She has since continued to build her career with a variety of roles. Notable anime credits include voicing Organ in Demon Lord, Retry! R in 2024 and being cast as Eku Harusaki in I Don't Want to Become a Dragon Girl! in 2025. Her work also extends to video games, with appearances in titles such as the Idoly Pride game and Akashic Chronicle.

Beyond anime and games, Tachibana is active in other areas of the entertainment industry. She is a member of the voice acting unit DayRe, which she formed with other third-generation talents from her agency. Her work also includes performing in digital comics, narrating videos for platforms like YouTube, and contributing to audiobooks. Through her involvement in projects like Idoly Pride, she has also released numerous character songs.
