Cocoro Yazawa

Cocoro Yazawa makes her official debut in the second season of the anime as the second-born child in the Yazawa household and Nico's closest younger sister. Polite and surprisingly mature for her age, she deeply admires Nico, who once claimed to be the driving force behind μ's. That admiration sparked in Cocoro a genuine passion for idols. Throughout the story, her warmth toward her family serves as a catalyst that brings out Nico's nurturing and dependable big-sister side.
