This is how the opening goes in Ryan's Quest: 358/2 Days.
The Organization is seated in the Round Room
Saïx (voice): Pitiful Heartless, mindlessly collecting hearts. The rage of the Keyblade releases those hearts. They gather in darkness, masterless and free... until they weave together to make Kingdom Hearts. And when that time comes, we can truly, finally exist.
Axel and Ranyx sit on the ledge of Twilight Town's clock tower
Axel: Ranyx...are you really sure that you don't have a heart?
Ranyx: I dunno. I can't...just look inside. But I figure... if there is something in there...inside us---then we'd feel it, wouldn't we?
Axel: True enough.
Axel hands Ranyx a bar of sea-salt ice cream. Ranyx is surprised. He chuckles and takes the ice cream. The opening credits begin to play, accompanied by several scenes depicting each of the Organization members and the song "Sanctuary" playing in the background. Towards the end of the opening, Ranyx is seen waking up in front of The Old Mansion in Twilight Town. A figure wearing a black coat emerges from a corridor of darkness and walks toward him
??????: You seek answers.
The man waves a cloaked arm between the two of them and the word 'RYAN' appears in the air, the letters shiny, silver, and hovering
??????: You feel nothing. Nothing is real. I can give you purpose.
The man waves his arm again and the letters swirl around Ranyx, gaining momentum until they're barely visible as letters. The man slams his fist into them and four points of golden light shoot out, forcing Ranyx to flinch. He opens his eyes and sees a new golden letter X hovering before him. The silver letters rejoin with the X in their center forming a new word, turning fully golden...
Xemnas: That is right---the new you.
Later, Ranyx walks through Twilight Town, seeing a group of kids eating ice cream. He stops and starts to turn around, when Axel appears and places a hand on his shoulder. The two proceed to eat ice cream atop the clock tower, Axel showing distaste for the treat at first. The scene returns to the duo on the tower prior to the credits starting)
Axel: Man, I miss the old times. Still got it memorized? The day we met, when you got your new name, you and I sat right here, just like this, and watched the sun set.
