Yuki Yomichi is a Japanese voice actress, YouTuber, and singer born on November 21, 1999, in Sapporo, Hokkaido. She began her entertainment career in her third year of middle school after being scouted by a local talent agency in Hokkaido, where she worked as a MC for local television, radio, and events. Her initial foray into voice acting came through an offer to appear in the game Yuba no Shirushi, which led her to enroll in a voice acting training school in Tokyo. She was formerly affiliated with the agency RERAISE from July 2018 to July 2019 and joined Quatre Stella in November 2019.

Yomichi made her anime debut in 2018 with a role as Chiaki in the television series Sono Toki, Kanojo wa.

In 2023, she was cast as Azami Himeno in Rokudo's Bad Girls and as Sachi Minato in Ippon Again. Beyond these roles, her anime credits include a part in the 2022 series小邪神飞踢X. In video games, she voiced Tsumugi Tamaori in Samurai Maiden in 2022.

Yomichi is also a prolific YouTuber, having launched her personal channel in June 2018 where she shares content related to her passion for motorcycles, as well as singing and gaming. A self-described motorcycle enthusiast, she holds a large motorcycle license and owns multiple bikes, including a Honda Super Cub, which directly connects to her lead role in the anime of the same name. Her multimedia career extends to music; she made her solo singer debut under Universal Music Japan in 2022 with the mini-album Hatsuyuki First Love. She has also been featured in magazine photo shoots and released a photo book titled Himegoto in 2021, which ranked highly on Oricon and Amazon charts.
