President Mariko leads Sweetfish Productions, the management company for the Lovely Idol groups. She abruptly postpones the scheduled debut of the third generation idols just before their first performance. Offering no specific reason to their manager, Tomohiro Fujisawa, she directs him to discover what the new generation lacks himself. Mariko operates with a serious, businesslike approach, prioritizing the quality and readiness of her company's idols. She demands high performance from employees and makes decisions based on her assessment of what ensures the group's success, setting directives without micromanaging the solutions.
