Izumi Shimomura

Izumi Shimomura is an Ajin. Her name is taken from her birth father's last name (Shimomura) and her mother's maiden name (Izumi). Her former name was Yōko Tainaka. Izumi is an attractive young woman with short, black shoulder length hair that appears rather spiky at the start of the series and large, grey eyes (dark red in the anime) with long, prominent eyelashes. There is a small mole under her left eye. Her usual attire is a black suit with a white buttoned shirt underneath, black pants and shoes. When she attended high school, she wore a standard uniform with a tie, skirt, blazer and a white shirt. At one point in the series, she wore a pink short-sleeved flannel shirt with jeans as her casual wear, saying that "She didn't have anything else." Izumi is a rather quiet and reserved individual. She talks mainly when informing Yū Tosaki about something. Her answers are usually short and to the point. Even though she is an Ajin, she chose to live with humans in secret and doesn't seem to be consumed completely by resentment towards humans despite her background. She seems to be quite intelligent and understanding, for example towards Tosaki and when interrogating Kei Nagai's younger sister, Eriko Nagai. However, despite her initial stoic appearance, she can get embarrassed easily (for example when she said too much to Eriko and when Tosaki commented on her casual clothes). Due to her past trauma caused by both of her parents and love life, she became very depressed and suicidal, often cutting herself and eventually trying to commit suicide.
