Birthday: May 5
Izumi is a student in class 3A of Honoda Junior High, and two years younger than Tomoya, and it was through Tomoya's influence that she became interested in otaku culture. She is deeply grateful to Tomoya for this. There is rivalry between Eriri and Izumi, then Izumi decided to compete with Eriri in the next Winter Comiket. Izumi made up her mind to be the illustrator for her brother Iori's dōjin circle "Rouge en rouge."
