T.M. Opera O is a bold and energetic Uma Musume known for her short, outward-turned chestnut hair and a crown-shaped accessory. She calls herself the "strongest and fastest genius Uma Musume in the world" and is famous for her flashy, operatic way of speaking and a very high opinion of herself. Her roommate is Biwa Hayahide, and she has close connections with Meisho Doto, whom she always encourages. She works hard in both training and racing, aiming to become the "Overlord at the End of the Century" who gives hope and courage to the audience through her victories. T.M. Opera O shines with true power, loves to perform, and leaves an unforgettable impression wherever she goes.
T.M. Opera O has vibrant purple eyes and short, chestnut-colored hair that flips outward. She wears yellow earrings with a green jewel on her right ear and always sports a pink crown on the right side of her head, matching her "Overlord" theme.
Her racing outfit features pink and yellow, resembling a royal opera costume. She wears a white and pink pleated skirt with pumpkin-like shorts, yellow armor decorations, and a pink cape. Her boots are yellow with white and pink knee-high socks.
Her casual clothing is a light blue blouse, checkered pants, and a navy long jacket—stylish, but without her signature crown.
Her Christmas event costume is a radiant, "Sun King" outfit from a stage play inside the story.
She is described as the Uma Musume with the smallest ear model based on fan investigations.
T.M. Opera O is extremely narcissistic, always talking about her own beauty and strength. She refers to herself as "I" (using the boyish "boku") and believes truly that anyone who doesn't know how great she is, is missing out.
Her energy is always high—she laughs out loud, makes grand gestures, and talks as if she’s starring in her own opera. She compares her own sparkle to stars and the sun and feels motivated by looking in the mirror.
Even though she is so self-confident, she is kind and never puts others down. She deeply praises the good points in other Uma Musume, notices when someone is sad, and helps them with her infectious positivity.
She sometimes feels a little lonely because her overwhelming presence and strength make it hard to have many close friends, but she keeps this to herself.
T.M. Opera O is clever and can improvise theater on the spot, but struggles with boring or unemotional things like regular schoolwork.
