Originally a nurse, Momotsuki was scouted by her agency in 2017 and entered the entertainment industry as a gravure model, attracting attention due to her day job.

She is also a regular performer on the Zeroichi TV YouTube channel and has made her voice acting debut in Love After World Domination (2022).

[12][13] As her job offers increased, she moved to Tokyo to further develop her entertainment career and attended various classes related to acting and modelling, as well as English and Chinese language lessons.

[5] She also served as a judge for the DC Comics cosplay contest at Tokyo Comic-Con 2018[16] and made her commercial debut for the mobile game For Whom the Alchemist Exists [ja].

[24] The films were released on the Toei Tokusatsu Fan Club (TTFC) service and are the first spin-off media starring a villain character in the Super Sentai franchise.

Photography for the book took place on Ishigaki Island, Okinawa, and the title was both meant as an expression of her "immaturity" and a homophone of "tangerine" (mikan), inspired by the words "peach" (桃, momo) and "pear" (nashi) in her name.

[33] That month, she also served as an ambassador for DC Comics' "The Dawn of Superheroes" travelling exhibition and threw out a ceremonial first pitch for a baseball game at Vantelin Dome Nagoya in cosplay as Supergirl.
