As her name suggests, she's the coffee addict character of the series. While she looks like she would be "the creepy one", with her black hair, her pale skin and her flat yellow eyes, she's actually a nice if introverted person (Not helping is the grungy look of her racing outfit portrait, courtesy of k-suwabe, her designer). She does however, have a thing with the occult. She is apparently able to see an invisible "friend" who also resonates at the presence of certain other girls.
A horse girl. She has long black hair with a long fringe almost covering her left eye and a contrasting white ahoge. She also has yellow eyes that are almost glowing and wears a blue-green rectangular ear piercing on her right ear. Also has long bangs and hair between eyes in most images depicting her.
Her likeness is often appropriated as the appearance of fan-created renditions of Sunday Silence (the original horse's sire), as the real Manhattan Cafe was said to be the spitting image of Sunday Silence. As to reinforce this point, her invisible "friend" is strongly implied to be Sunday Silence due to which girls they resonate with (Other RL progeny of Sunday Silence and Mejiro McQueen).
