Emu is a short girl with big sparkly pink eyes and pink hair cut into a short, messy bob. Her voice is bright and positive. She wears the grey-and-white standard uniform for her school, with a colorful pink cardigan riddled with stickers and a badge; a design she proudly came up with herself. This intution is shown in her first encounter with Mafuyu, whom she meets through the Sports Festival. Upon meeting, Emu is quick to become terrified of Mafuyu when she realizes her smile doesn't seem real.
