Summary
An Uma lands face-first in a city she doesn't recognise. With no memories, no contacts, and the fabled Tracen Academy never knowing she exists, how will her life unfold?
TL;DR I wanted to write horsefem, but I am absolutely horrible at capturing the vibe of the Tracen setting, so I ported the whole thing over to a near-future cyberpunk setting instead.

Summary
The winning equation.
A comprehensive mathematical framework for understanding and predicting every aspect of Umamusume racing. The instrument with which the data-driven Team Mira made a name for itself in the Twinkle Series during its early years. Irrefutable proof that applied logic can win over raw talent.
At least, that's how its co-author has seen it ever since his first trainee entrusted it to him. But lately, no matter how many times he runs the numbers, his charges keep coming up short. If he could just identify what has been missing from his implementation, he could fix his mistakes, reverse his team’s fortunes, and hopefully end this far-too-familiar feeling of discordance, right?
Luckily, the equation's primary author has her own theory on how to get him back on track.
(Takes place after the events of the Run! Mecha Umamusume scenario. Expect spoilers for it.)
