Izumi is of average height and has a slim figure with pale skin. He is noted to be quite handsome with long lashes [8] and a slightly feminine-looking face, a feature that others often point out.[9][10][11] He also has deep blue eyes, messy black hair that goes down to his nape with parted bangs, and thin eyebrows. Izumi has a total of nine piercings: four down each ear and one on his lip, all of which were done by himself.[12] He also has dark-colored tattoos on his left shoulder, upper left arm, and side. In his first appearance, Izumi is seen dressing heavily to hide his tattoos, wearing his winter and blazer. He keeps his hair shoulder-length and straight to avoid drawing attention to his piercings and wears thick-rimmed glasses. Out of school, he dons a more casual appearance and is seemingly indifferent about the fact that others can see his piercings and tattoos. He removes his glasses and keeps his hair tied into a small ponytail, with a few bangs framing his face. Occasionally, he wears a lip ring, chain, casual outfits, and various accessories. When he first starts dating Kyouko Hori, Izumi decides to cut his hair short and withdraws from wearing glasses [13]. With his side bangs reaching just past his ears, Izumi's piercing holes become visible, but a few piercings—precisely the one on his lip—close up due to him not using them. His new appearance sparks the attention of many, and he is considered quite attractive by the girls in his class, much to Kyouko's annoyance.
