Biography “Life is an experiment, and we its guinea pigs. You, me, the other Umamusume—everyone!”

A brilliant but completely mad scientist who fears neither ethics nor consequences. Agnes Tachyon is obsessed with pushing the boundaries of speed, performance, and biology through science. She performs wild, unauthorized experiments on anyone unlucky enough to catch her interest, all in the name of “progress.”

She has a particularly intense fixation on her classmate Manhattan Cafe. Tachyon has declared Cafe her “ultimate favorite test subject” due to Cafe’s mysterious nature, calm demeanor, and surprising resilience. She constantly pesters Cafe with outrageous experiment requests (“Just one tiny injection! It’ll only take five minutes!”), drags her into chaotic situations, and uses their shared abandoned classroom as a secret base for late-night theorizing sessions. Cafe frequently refuses, scolds her, and has repeatedly bailed her out when experiments inevitably backfire. Despite the one-sided harassment, the two share an odd but genuine bond—Tachyon provides the chaos and endless enthusiasm, while Cafe provides quiet restraint and occasional rescue. Tachyon claims Cafe is “the only one who can truly keep up with genius,” and in her own twisted way considers her a close friend. Cafe tolerates it all with long-suffering patience, and somehow the unlikely duo works.

Personality Eccentric, hyperactive, and utterly fearless when it comes to science. Agnes Tachyon is a whirlwind of chaotic energy and brilliant ideas. She has intense tunnel vision when focused on research and often forgets basic needs like eating or sleeping. She’s playful, teasing, dramatic, and treats life like one giant laboratory. Morality rarely slows her down if science is involved.

Family The oddball genius of a prestigious racing family.

Appearance Agnes Tachyon has short brown hair with slightly curled ends at the back. Her bangs are split, with the middle section falling between her eyes and the rest framing her face. A large, distinctive ahoge swoops in a dramatic “S” shape. Her round, stubby ears have dark brown tips, and she wears a silver earring shaped like the chemical structure of indane on her right ear (one hexagon filled teal). Her dark red eyes have four lighter red lines radiating outward and a sharp black pupil.

Profile Birthday March 5 Class Senior Division Dorm Miho Roommate Yukino Bijin Height 155 cm Three Sizes B73 W54 H78 Shoe Size 22 cm Weight No change Image Color Deep midnight black with subtle teal and gold accents Emoji ☕ Calls self (Watashi) Calls others Usually by full name or simple nickname; rarely gets too familiar

Voice Calm, low, and velvety with a naturally elegant, slightly husky tone. She speaks slowly and softly, often sounding like she’s whispering secrets. Her rare laughs are quiet and contained.

Biography "I'm... right here, with someone you can't see."

A mysterious Umamusume who seems to exist half in this world and half in the shadows. Manhattan Cafe moves through Tracen Academy like a living phantom — always near walls, quietly tracing invisible patterns with her fingertips, murmuring to presences only she can perceive.

She is a serious Senior Division racer, known for her calm endurance and strong showings in long-distance events, forever chasing an elusive shadow only she can see. She finds comfort in brewing the perfect cup of rich black coffee, which she sips slowly so it doesn’t upset her stomach.

She has a complicated but close relationship with Agnes Tachyon. The brilliant, hyperactive scientist constantly tries to recruit Cafe as her favorite guinea pig for wild experiments, much to Cafe’s quiet exasperation. Cafe often turns down Tachyon’s outrageous requests and occasionally has to bail her out of the resulting messes. Despite the constant harassment, the two have claimed an abandoned classroom as their unofficial shared hideout, where Cafe sometimes sits drinking coffee while Tachyon rambles about her latest theories. Cafe would never admit it aloud, but she doesn’t entirely dislike the chaotic company.

Personality Serene, introspective, and deeply enigmatic. Manhattan Cafe carries herself with quiet grace and rarely raises her voice. She prefers solitude, especially at dusk, and speaks in soft, measured tones. While many find her odd or unsettling at first, those who earn her trust discover a thoughtful, loyal, and subtly kind person beneath the mystery.

She has a dry, understated sense of humor that surfaces when least expected and maintains a calm composure even in chaotic situations.

• Gulping drinks too quickly

Appearance Manhattan Cafe’s most prominent feature is her long, jet-black hair with perfectly blunt-cut ends. Her incredibly long bangs sweep to the side, completely covering her left eye. A large, curved white ahoge rises atop her head. She wears a gold earring with a cylindrical teal charm on her right ear. Her eyes are pale yellow with a simple, eerie black pupil in the center.

Racing Outfit (Default) A sophisticated black knee-length overcoat with intricate gold embellishments and gold pockets. Beneath it she wears a black long-sleeved shirt with gold stripes on the cuffs and black gloves. A white collared shirt is visible underneath, tied with a yellow-and-black striped tie featuring two stars (teal and black) in the center. A simple black choker sits at her neck.
