Special Week is the co-protagonist for the first season of Umamusume: Pretty Derby as well as the franchise's mascot. She is a student at Tracen Academy.

Despite her humble roots as a country girl, she dreams of becoming Japan's number one Umamusume and defining that for herself.

Born in Hokkaido, Special Week is a bright and cheery, hardworking Umamusume. After losing her birth mother, Special Week was raised by her mother's friend. Now, she hopes to make both her moms proud by fulfilling her promise of becoming Japan's top racer. Though she may falter along the way, her indomitable spirit ensures that she runs ever forward.

In her daily school life, Special Week is sensitive and encouraging, though she sometimes has trouble making friends due to not being around many umamusume in her youth. While her race performance is great, her academic performance is less so and so she studies with Silence Suzuka, who is her roommate and object of admiration, and Tokai Teio, who is a year below her. Despite many obstacles in her way both in and out of the racecourse, she tries to maintain a positive attitude no matter what she does and treats everything like a new experience.

Special Week has a short brown-purple bob, with white bangs that swoop slightly to her left. She has white braids tied around to the back of her hair, and short, stubby brown ears, with a purple bow on her right ear. Her round and cheery eyes are light purple.

Her race outfit is very idol-like in appearance. She sports short-sleeved white cropped jacket with pink sleeves, and a pink collar. Underneath her coat is a white collar fastened with a dark purple ribbon, and a dark purple top underneath, fastened by two golden clover-shaped medals. She wears a white skirt with a prominent purple zig-zag pattern on the base, and a pink petticoat underneath. The tail-hole on the skirt has a large purple ribbon above it. She wears white thigh-high socks with pink lines at the top, with dark purple ribbons on either side. Both of her shoes are ankle boots with pink collars on the top. Her left shoe is dark purple, and her right is white. She wears two pink cuffs around her wrists.
