Momoko Priscilla is a wealthy and highly ambitious individual consumed by the desire to become the world’s most famous idol and to eclipse even the legacy of Audrey Hepburn. She exhibits a pronounced sense of vanity and entitlement, often regarding others with a condescending attitude. She firmly believes that those more successful than herself are undeserving and treats them with open criticism.

Her narrative centers on an intense, one-sided rivalry with Nagisa Otori, Japan’s top idol, whose popularity and success she deeply envies. Driven by this fixation, Momoko establishes an entire school dedicated to training idols with the explicit goal of dethroning Nagisa. Unbeknownst to her, Nagisa remains entirely unaware of Momoko’s existence and sings purely for personal enjoyment, with no interest in competitive fame.

Despite her considerable efforts and relentless pursuit of glory, Momoko Priscilla never achieves her objective of surpassing Nagisa. Her actions, fueled by envy and a hunger for recognition, yield no meaningful success or acknowledgment from her rival.
