Ei is a young woman with dark purple hair braided into a long braid. She has bright purple eyes, similar to the color of an electric cell, and has a mole under her right eye. She also uses red eyeliner. Although Ei is still relatively resilient compared to most people, she's noticeably more emotional and friendly, although sometimes she's quite self-centered. In her drunken state, she's much more emotional and self-centered. Also a little obtrusive.
