Asuka Sakurai, currently working at the Kiri Pro talent agency alongside Komugi Nakahara, was once a movie actress before being demoted to the agency, signaling a steep career decline that threatens her acting future. Despite this setback, she works diligently and more responsibly than colleagues Komugi and Megumi, focusing on her duties with few complaints.

Typically composed, she possesses a temper that emerges when provoked. Unlike Megumi and Runa, who often antagonize Komugi, Asuka consistently respects Komugi and develops a genuine friendship with her, standing out within the agency's competitive environment. This respectful bond endures as she navigates the challenges of maintaining her idol and acting career amidst professional instability.

A notable personal quirk is her pronounced dislike of Osaka, notably revealed in Magikarte Z. Throughout her appearances, she balances professional pressures—including the stigma of her demotion and her precarious position—with her interpersonal relationships at the agency, particularly her supportive bond with Komugi.
