In Kingdom Hearts II, Sora and Riku are stranded in the Dark Margin and receive a letter in a bottle from Kairi. Riku takes it out of the bottle, looks over it quickly, and says to Sora, "I think it's for you". Sora then reads it aloud. "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
