What would happen if Kingdom Hearts was completed

You would see a movie. The movie would be about how Sora closes the Door to Darkness with Riku and Mickey still inside. After that, Sora reunites with Kairi, but only for a little while. After they say little, the land they are standing on breaks apart and slowly drifts away from each other. Sora promises Kairi that he'll come back soon. Kairi ends up in the Destiny Islands. There, she goes to the Secret Place and sees the drawing that Sora drew of them together with him giving her a Paopu Fruit. Kairi sheds a tear while the credits show. After the credits, you see Sora, Donald, and Goofy walking a long path until they see Goofy with a letter in his mouth with the King's seal. Sora, Donald, and Goofy start running after Pluto along the path where it will take them to a place with another adventure ahead. After that, YOU MIGHT see the secret movie if you unlocked it. It would be about Roxas in the Organization when he is battling Heartless in The World That Never Was. It is also the part before he battles Riku, who is blindfolded for some reason. After those scenesj, you see a girl on an island who sees 'something' fall out of the sky falling towards the water. After all those movies, you finally see the 'The End' screen.
