Also known as Cat's Ear, Eromes is an Amanto with cat ears. She becomes Shimura Shinpachi's love interest after he presumably saves her from a drunk Matsudaira harassing her on a mass transit. As a thank-you gift, she then buys Shinpachi a cake, cat ears and goes out with him on a date. Later on it's revealed that it was all just a scam set up by Eromes, who is a self-proclaimed phantom thief who steals love, but actually only steals her victim's wallet or valuables. She is the main antagonist of Train Samurai Arc
