Pocket flushed. Her golden eyes burned. “Interesting? I’m standing here practically glowing and all you can say is ‘interesting’?”
Tachyon didn’t blink. “Well, statistically speaking ”

Summary
It’s the gentleness of her tone that keeps Cafe somewhat at peace despite the tension. Her face wore an indescribable expression, not that this was much different from the spontaneous range of looks that read all incorrect emotions- it’s the familiarity, the roundness of her glaring eyes, the distraction from the pounding of her body.
Tachyon’s mind is a library of titleless novels, it takes Cafe one day at a time to read the entire catalog.
Cafe was only meant to recollect herself for fifteen minutes. Alone, uncomforted.

The way T.M. Opera O's gaze shifted as she answered sent a thrum of anticipation through Tachyon’s body, one almost akin to the first time she’d set foot on the turf, the first time she’d felt the thrill of a real race.

+++
When Tachyon accepts the overlord's request for her researching expertise, she's excited to see how such a powerful Umamusume's body works on such an intimate level.

Summary
“Oh, I have something planned for you. Don’t even worry.” Tachyon wouldn’t take her eyes off of Opera as she walked up to him and set her materials on the lab table adjacent to him, her back finally turning to work on whatever she had planned for tonight.
She hummed a song that Opera couldn’t recognize as she prepared a bag on an IV pole. His pulse quickened slightly – unable to separate fear from excitement. Opera instinctively searched for the vein running down his arm all the way to his wrist, the sensitive skin itching to be pierced.
His heart skipped a beat when Tachyon turned around to face him with the needle end of the IV tubing pinched between two fingers, her other hand wheeling the pole to stand guard beside Opera.
or,
Tachyon's found herself a fine, obedient little guinea pig. She has some tests in mind.

Fenri, a trainer at Tracen Academy has always been searching for something in life.
