Character Description
The hyperactive girl of the MILLION STARS, Umi is a an athletic girl who excels at almost every sport, and most of her cards depict her doing various sports. She has a very energetic personality to the point that she cannot stand being inactive. Umi can’t calm down when she's not doing anything-- in fact, she once said that when she remembers that there are other idols out there who are working their hardest, her body is unable to rest.
Umi is not only good with active sports like football or basketball; she is also good with gymnastics, and she took ballet lessons when she was younger. All of this made her body very flexible. While she is a sporty girl, she's definitely not a tomboy and she's happy to wear cute dresses. While Umi has great confidence in her legs, she lacks confidence in the upper half of her body and she's not good with makeup.

Trivia and Fan Culture
Trivia
- Umi is a terrible cook. She once tried to make a Christmas cake and it ending up being elastic like a gummy candy, making it inedible.
- Umi calls other idols by nicknames, such as calling Yuriko "Yuririn" in the beach volleyball event, calling Sayoko "Sayochin" in her caravan story, and calling Daigo "Daidai" in POPLINKS.
- According to the Theater Days Beach Volleyball event, she has an older sister who is a professional ballet dancer. She later appeared in Umi's Hitomi no Naka no Sirius event card. In her [Sports! Sports! Sports!] card, she used to dream to be just like her sister. In the Ubugoe to Club event, Umi mentions that her sister is currently in Russia as part of a ballet company.
- In one of her cards, she plays the role of Okita Souji, captain of first division in Shinsengumi who died from Tuberculosis. Uzuki Shimamura and Kaoru Sakuraba also played him in other events.
- In 2018, Umi and Sayoko became the first characters to participate in 3 albums released in 3 consecutive months: THE IDOLM@STER MILLION THE@TER GENERATION 10 Senkou☆HANABI Dan (July), THE IDOLM@STER MILLION THE@TER GENERATION 11 UNION!! (August) and THE IDOLM@STER THE@TER BOOST 01 (September).
- She shares the same birthday with Kyoko Igarashi and Rin Shibuya.
Fan Culture
- She is nicknamed "Umimi" by fans because her name's kanji (海美) can be read as such. She even uses it herself in some of her card's text and event dialogues.
