Kairi's Letter

In Kingdom Hearts II, Kairi wrote a letter to Sora. She wrote it the day before Roxas's mind made contact with Kairi's. She put it in the water at the coast of the mainland, explaining to her friend, Selphie, that she started to remember Sora's name.

 * "Thinking of you, wherever you are.
 * We pray for our sorrows to end, and hope that our hearts will blend.
 * Now I will step forward to realize this wish.
 * And who knows:
 * starting a new journey may not be so hard,
 * or maybe it has already begun.
 * There are many worlds, but they share the same sky —
 * one sky, one destiny."
 * — Kairi

Kingdom Hearts II
On the fourth day, after Roxas makes contact with Kairi's heart, she goes to the shore and releases a letter in a bottle into the surf. As it drifts away, she tells Selphie she wrote it to the boy she can't remember, telling him she'd find him one day.

After defeating Xemnas, Sora and Riku are stranded at the Dark Margin. While sitting on the shore, they find the bottle washed up on the shore. Riku takes out the letter, looks it over, and realizing its for Sora, hands it over to him. Sora reads the letter out loud, and the Door to Light appears before them. Sora stands up and offers a hand to Riku, who gets to his feet. They walk into the light and suddenly find themselves falling through the sky over Destiny Islands. They splash down into the water, and they are met at the shore by Kairi, along with Donald Duck, Goofy, and Mickey Mouse.
