Toomi (十味, Tōmi) (real name unknown) is a Japanese model, gravure idol, tarento and dancer. When she was in high school, Toomi posted a Niconico dance video, and after receiving a request to appear in an event, she gained popularity. After leaving university, she worked as a model. She was then scouted by a representative of 01familia, and she joined it in June 2018. On July 26 of the same year, she made her gravure debut in Weekly Young Jump magazine, and on October 11, she made her cover girl debut there.

Toomi is a member of the idol group #2i2 (pronounced "nii-ni") since 2020. She is the main vocalist of that group, and since she is the most "senior" of the members, she is in charge of the group's coordination. She was once a competitive skier. Her father was a ski instructor. She had applied for an audition for Hello! Project when she was in her second year of junior high school. She joined 01familia because she liked Nashiko Momotsuki, who belongs to that agency. She became interested in mahjong during the COVID-19 state of emergency lockdown period in early 2021.
