Figure | Umamusume: Pretty Derby | Special Week | Banpresto

Special Week is one of the main characters of the anime series, Uma Musume: Pretty Derby. Originally from Hokkaido, she moved to Tokyo to attend the Tracen Academy. Under the tutelage of Trainer, she was able to win two races in a row and is on the path to becoming Japana’s best horse girl.

Umamusume: Pretty Derby is set in a fictional universe similar to the real modern world but featuring the titular Umamusume, female kemonomimi with the ears, tails, and capabilities of horses who live alongside humans and replace actual horses in the franchise's setting. Many Umamusume are inspired on real-life racehorses of the past and present who seek fame and fortune as both racers and idols by competing in organized races akin to middle-distance track events.

The series centers on Umamusume who attend the elite Tracen Academy in Tokyo and train to compete in the Twinkle Series of professional races organized by the Umamusume Racing Association (URA). The main stories across the series are focused on specific girls and loosely based on the racing careers of the racehorses they are based on.
