Anju Yuki is a third-year member of the popular UTX High School idol group A-RISE, performing alongside Tsubasa Kira and Erena Todo. She possesses long orange curly hair with straight bangs and purple eyes, maintaining a composed, princess-like demeanor with a sweet vocal quality and minimal concern for competition or fan interactions, including those with rivals like Nico Yazawa and Hanayo Koizumi. A-RISE inspires other groups, including μ's, initially appearing as rivals but developing respect after admiring performances like "START:DASH!!" and "Snow halation." They later support μ's by offering UTX High School's rooftop stage for their Love Live! preliminary. Anju graduates during the anime series but continues with A-RISE into the movie's timeframe. Following A-RISE's previous Love Live! victory and μ's subsequent win, Anju participates in μ's initiative for a large-scale school idol festival, collaborating directly with Kotori Minami on costume design. She observes μ's final performance at Akiba Dome alongside Tsubasa and Erena, reflecting the ongoing connection between the groups as μ's approaches disbandment.
