She gained widespread recognition for her role as the antagonist character Yodonna in the tokusatsu television series Mashin Sentai Kiramager and its related franchise projects.

Raised in Toyohashi, Aichi Prefecture, Momotsuki began cosplaying during her third year of high school at local gatherings, adopting her professional moniker from the mascot character Funassyi and a webcomic figure. After high school, she worked as a nursing assistant in her hometown to fund her nursing education, officially qualifying as a nurse in 2016. Discovery by her talent agency in 2017 led to her entertainment debut in Weekly Young Magazine. Moving to Tokyo to advance her career, she took acting, modeling, and language lessons while continuing to work at a medical clinic.

Momotsuki expanded her television presence through talk shows, cosplay contests, and commercials, making her dramatic acting debut in 2019. That same year, she achieved a key career objective by securing a position as a regular fashion model for the magazine Bis. In 2020, she joined the cast of Mashin Sentai Kiramager. Her popular character subsequently headlined the web-exclusive spin-off films Yodonna and Yodonna 2, marking a historic first for a villain character in the Super Sentai franchise. Her screen credits also include roles in Garo: Versus Road, Short Program, and voice work for Love After World Domination.

In addition to acting, Momotsuki has published commercial photobooks, including Mikan in 2020 and Peachy in 2022. She serves as a host for 01familia's television broadcast and online media content on the Zeroichi TV YouTube platform.
