Piina, elder sister to Papi and president of Pirika, shares a resemblance with her brother but stands slightly taller, distinguished by her attire featuring a white cloth with an orange collar. Amid General Gilmore’s coup, she forcibly secures Papi’s escape via rocket, sacrificing herself to remain on Pirika, where PCIA agents capture her. Imprisoned, she confronts Dracorl, Gilmore’s subordinate, who disregards her insistence that Papi would avoid Gilmore’s coronation. At the ceremony, Piina witnesses Papi openly defy Gilmore, galvanizing Pirika’s citizens into rebellion. This act condemns both siblings to execution. During the attempt, Piina displays palpable relief and joy when Nobita rescues Papi from a rooftop fall. Having raised Papi after their parents’ death—symbolized by a locket carrying their photograph—Piina later shares an emotional exchange with him following Gilmore’s defeat. She affirms their bond and acknowledges his growth, prompting Papi to release previously suppressed tears, which she accepts. This character originates solely in the 2021 film adaptation.
