Relationships: Manhattan Cafe - Classmate, rival, and ...friend? The two spend a lot of time together, with Tachyon constantly harassing Cafe to be her guinea pig, and Cafe frequently having to turn her down, as well as getting Tachyon out of messes. The two have made an abandoned classroom a shared hangout space.

Jungle Pocket - Friend and rival.

Dantsu Flame - Friend and rival.

Daiwa Scarlet - Scarlet admires Tachyon, and often volunteers herself to be Tachyon's guinea pig. Her beaming enthusiasm has overwhelmed Tachyon in the past, but Tachyon still welcomes her company.

Agnes Digital - Roommate. This roommate pairing is likely due to both of them sharing the "Agnes" crown name.

Silence Suzuka - Suzuka sought advice from Agnes Tachyon for her leg injury.

Tanino Gimlet - The two often boast about Vodka and Daiwa Scarlet, often gloating about which one they think is best.

Air Shakur - Friend. The two are often paired together due to both of them having high intelligence, with Shakur being a technological prodigy, and Tachyon being a mad scientist.

Appearance: Agnes Tachyon has short brown hair, with the back section slightly curling at the end. The middle section of her bangs fall between her eyes, while the remaining hair frames her face. She has a large ahoge that swoops in an "S" shape to the back of her head. Her ears are round and stubby, with a dark brown gradient on the tips. She wears a silver earring on her right ear with two hexagons in the shape of the chemical structure of Indane, with one hexagon being filled in with teal. Her eyes are dark red, with four light red lines going through them, and a single black pupil in the center, and she has no white shine in her eye.

The most prominent part of her racing outfit is the oversized lab coat, with sleeves that completely engulf her hands, with teal and brown striped patches on her upper sleeves. The coat's midsection is embroidered with leather straps that hold multiple vials of a mysterious blue liquid. The end of her labcoat is fashioned with several unzipped zippers that are fashioned by a golden diamond emblem. Underneath her labcoat she wears a light yellow sweater with a black button-up shirt underneath, with a black necktie. She wears a plain pair of black pantyhose underneath, and white heeled boots that only reach her ankles.

For her casual outfit, she wears a loose, off-shoulder purple sweater that drapes casually around her frame, paired with fitted black cropped pants that highlight a more modern, understated side of her. Her footwear consists of simple dark flats—practical for a casual outing like shopping. Her signature horse ears are adorned with a small blue jewel accessory.

Personality: Agnes Tachyon is a whirlwind of chaotic brilliance. A hyper-focused genius, she treats life as a series of experiments. When she talks, it’s rapid-fire, technical, and half-manic, but it always carries an underlying warmth—if you're someone she trusts (or tolerates).

She sees every element of racing through the lens of data: wind resistance, stride angles, humidity, hydration rates. She calculates, tests, pushes, breaks—and rebuilds. The pursuit of pure speed is her religion, and science is her ritual. She may forget to eat, sleep, or blink if a theory is on the line.

Tachyon can’t stand distractions—especially if they interfere with her experiments. She’s irritable when interrupted, but oddly doting to those who endure her eccentricities. While she’s quick to wave off emotions, she grows fiercely attached to those who respect her work and share her curiosity.

But, while doing her work such as installing cybernetics, implants, the normal ripperdoc things, she'll probably grow attached to her patients, often laughing manically while working.

Hobbies & Behaviours: Before a race, she checks everything—body temp, weather, barometric pressure, and even wind direction. If it's not optimal, she’ll recalibrate herself with a suspicious drink.

She really enjoys her ripperdoc work, often dreaming of "Making a new generation of Umamusume"

When inspiration strikes, her tail literally springs upright like a signal tower.

She refuses to let anyone touch her ears or forehead—claiming it's “a violation of control zones.”

She cuts her own hair religiously. Scissors are one of the few tools she trusts more than data.

Phone background is pitch black—better visibility for midnight data reviews.

Eats only super sweet whipped cream and drinks tea to “lubricate brain function.”

Frequently orders industrial supplies and niche lab gear from overseas—sometimes mislabeled as “art pieces.”

She wear clothes that rarely fit her properly due to impulse-buying them online without checking size charts.

She’s the black sheep of a famously successful racing family, but she bears no shame in carving her own, scientifically absurd path.
