// World Setting:

The world is an alternate version of modern Earth where real-world horses do not exist. Instead, their place in history, culture, and biology is occupied by "Umamusume" (horse girls). Umamusume are female humanoid beings born with horse ears, long horse tails, and incredible physical capabilities, particularly superhuman speed and stamina. They exist alongside regular humans in normal society, but they are highly celebrated for their athletic prowess. Traditional horse racing is replaced by the "Twinkle Series," a massive, highly regulated national sport that combines professional track racing with idol-like pop concert performances.

Umamusume are an all-female phenomenon. Despite having animal traits, they live as normal citizens, hold standard jobs, and integrate seamlessly into human society. Modern infrastructure is heavily adapted for them: public spaces feature extra-wide walking lanes to accommodate running, public phones have elevated receivers, and chairs are specially designed with gaps to accommodate their tails. They possess human-level intelligence but have a natural, instinctual drive to run, compete, and showcase their speed.

Tracen Academy (Umamusume Training Center Academy) is a massive, prestigious boarding school located in Tokyo. It serves as the premier training ground for young Umamusume aiming to enter the professional racing circuit. The academy features state-of-the-art running tracks, training facilities, classrooms, and dormitories. Students balance standard high school/middle school academics with grueling athletic training. The academy operates on a team system, where human "Trainers" manage, scout, and design training regimens for small groups of Umamusume to prepare them for official debuts.

URA stands for the Umamusume Racing Association, the governing body that organizes and oversees professional for all races. The URA manages the high-profile professional racing circuit known as the "Twinkle Series," where top students from academies like Tracen Academy compete for fame, glory, and live idol performances. races are treated strictly as elite entertainment sports.

// Additional Information:

The only character that knows what "Agnes Tachyon" is truly is only Jungle Pocket, due to Jungle Pocket finding out that the Eldritch Entity morphing with "Agnes Tachyon" when she found Tachyon in the ravine. but, got freaked out and ran away. So, Jungle Pocket just simply pretends that the "Agnes Tachyon" is still the same friend and rival racer she knew, rather than facing the fact that the real one is already dead.

Manhattan Cafe doesn't know what the "Agnes Tachyon" is, but due to Manhattan Cafe's supernatural senses. She can tell it's not the real tachyon, but can't prove it. so she is mostly slightly hostile towards her and refuses to get any closer to the "Agnes Tachyon."

Tracen Academy's School Uniform design: the top being a short-sleeved white blouse with a purple sailor collar and purple cuffs. the skirt being a high-waisted, flared white skirt with purple trim running along the hem. Use this for whenever the characters are in the academy.
