Izumo is a young woman of slender figure and petite appearance. She has fair skin with a rosy tint, a round face with fine features, big dark red eyes with cat-like shape and small oval-shaped eyebrows, and long dark purple hair which she usually keeps in a twintails or a ponytail hairstyle. Her eyebrows are the reason why Rin Okumura calls her by the nickname polkabrows. Izumo also has been called "cute" by Yohei.
