So knowing that context, let's cut back to how the film ends again. Ranka's monologue happens in the same verdant fields, surrounded by the supporting cast. She places a paper plane, the kind Alto taught her how to make, on the wreckage. And says to herself she believes Sheryl will wake up and that Alto will return. The phrasing here loses some meaning in translation, but she speaks with pretty clear certainty and uses a phrase that's overwhelmingly used to describe not just a return, but a return home. She then begins singing a song in prayer that's vaguely (always open to interpretation, obv) about how Alto has helped her grow and feel and love and how if she sings he'll hear her out in the endless cosmos. It's subtle, but once she starts singing, she begins to glow in green the way she always did when doing her magic fold-singing that would attract and communicate with the Vajra. During her song, there's a credit sequence montage of the events of the two films. The song and montage ends with images of Sheryl in a wedding dress, Alto as he says "I love you" to Sheryl, and then it cuts back to Sheryl in a coma, as she lips the final verse of the song implying she's waking up. And as she mouths that she can see the stars sparkle, her fold quartz earring begins to shine. The screen fades and the second half of the credits begins. A crowd chanting for Sheryl comes into audio-focus and Sheryl greets the crowd. And Sheryl responds to the chorus of fans, "Hi! Sorry to keep you waiting! If everyone calls out to me, miracles can always happen!" And then Sheryl and Ranka begin signing dShootin' Starb.
