Himeno Ayanokōji leads and centers Touou Academy's idol club. She earned recognition by placing fourth in the Love Live! SIF N Girls popularity poll, yet despite ranking in the top nine, was not selected for the main cast of the subsequent Love Live! Perfect Dream Project. Her character development unfolds through interactions with the Nijigasaki High School Idol Club. During a joint theater production between the schools, Himeno initially displays rivalry and jealousy toward Karin Asaka, culminating in a competitive confrontation in Episode 9. Witnessing Karin's performance shifts Himeno's perspective: she openly acknowledges Karin's talent, transitions from rival to admirer, and subdues her antagonism. Himeno maintains ongoing interest in Nijigasaki members, particularly Shizuku Osaka. She attends Shizuku's stage play "Rain in the Wastelands" alongside fellow Touou idol Misaki Shidou, supporting Shizuku's acting endeavors. While not central, her role illustrates inter-school dynamics and evolving relationships within the idol community.
