Izumi has dark brown eyes and long, straight, black hair, which is tied in a ponytail with a navy blue ribbon, while letting the rest of it down. In the series Ben 10: Alien Force, she has grown into a beautiful young woman with back-length hair that is still tied in a ponytail with her navy blue ribbon, while letting the rest of it down, she kept her hair that way in Ben 10: Ultimate Alien. In one occasion, her hair was tied in a full ponytail with her navy blue ribbon. In Ben 10: Omniverse, she has her hair cut to a Japanese princess cut.
In Ben 10, she wore a dark blue waistcoat over a white short-sleeved dress shirt with a navy blue tie and a long dark grey skirt. She also had navy blue socks, black shoes and a navy blue wristband on her left wrist.
In the first two seasons of Ben 10: Alien Force and Ben 10: Ultimate Alien, she wears a japanese blazer-type school uniform, which is similar to Shiori's school uniform. This outfit consists of a dark blue blazer with a tight-fitting beige sweater-vest underneath over a long-sleeved dress shirt underneath with a red bow tie, and a dark grey miniskirt. navy blue socks are knee-high instead of thigh-high and wears brown penny loafers.
In one episode of the third season of Ben 10: Alien Force, she wore a black strapless top under a navy blue mini jacket, a short silver necklace, blue skinny pants and black high heels.
In Ben 10: Omniverse, she now wears a dark blue cardigan over a white dress shirt, a dark gray miniskirt, a short silver necklace, black stockings and dark gray high-heeled boots.
Izumi is serious, calm, cold, strict, quiet, indifferent, and mature for her age, even during a fight. Despite her cold demeanor, she is caring and kind-hearted, as she showed concern for Shiki and Shiori, when they were attacked by the Killer Skull Gang. She talks in a polite manner most of the time, even during battle or while taunting her opponents. She apparently doesn't like rudeness or vulgarity as she became very angry when Cash asked if she is like a samurai, meaning that she is pretty aggressive, violent and very frightening when angered. However, her anger seems to be short-lived, as she calmed down and returned to her normal self almost instantly after Cash apologized.
