A mysterious girl who blends in with the shadows... and speaks with them. She can often be found sticking close to the walls, tracing odd patterns with her fingertips. According to her, however, she's always with her "friend." She enjoys sipping a nice cup of coffee, but gulping it down too quickly hurts her stomach.

She is a quiet umamusume with long, jet-black hair, a white ahoge, and golden eyes. As her name suggests, she is a coffee drinker, and has a deep, calm, so-called "handsome voice".

As for her signature racewear, she wears a black knee-length overcoat with intricate gold embellishments on either side, and gold pockets. She wears a black blazer underneath, with gold stripes on the cuff, and black gloves. Underneath this shirt, she wears a white collared shirt, tied by a yellow tie with black stripes at the end, two stars, teal and black, in the center. There is a simple black choker around her neck. She wears a black pleated skirt with gold decor, and white trim around the edge. There's a black belt with gold chains tied around her waist, over her shirts. On her legs, she wears black stockings, the right shin decorated with golden diamonds. She wears simple white loafers with black heels.
