Asuka Anzai emerges as a celebrated idol in Gosho Aoyama’s anthology story *The Santa Claus of Summer*, thrust into a race against time when teenager Keisuke Hara inadvertently triggers a weaponized satellite poised to annihilate Earth within 24 hours. After Keisuke’s intoxicated oversight erases the system’s deactivation code, Gray—a shadowy operative linked to the satellite—engineers a confrontation between the pair, exploiting Keisuke’s fervent admiration for the idol to reignite his fractured memory. Tasked as both muse and motivator, Asuka becomes an unwitting linchpin in Keisuke’s desperate bid to halt the countdown. The narrative confines her presence to this crisis, anchoring her solely to her public persona as an idol without delving into her past, inner drives, or connections beyond the immediate stakes. Her role culminates with the resolution of the emergency, leaving her arc defined exclusively by this pivotal intervention.
