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.
Kingdom Hearts II
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."
After this, the "Door to Light" appears before them. Sora stands up and turns to Riku, who has an injured leg. "We'll go together", he says, and holds out a hand. "Yeah", Riku replies, and gets up. They walk through the light and are suddenly falling through the sky over Destiny Islands. They crash into the water and are greeted by Kairi herself along with King Mickey, Donald and Goofy.
- Strangely enough, if the player waits at the main menu screen of Kingdom Hearts long enough, a small cutscene starts playing in which this poem is shown in with "Hikari"'s instrumental orchestral version playing as background music. The same poem is shown when one waits long enough at the main menu screen of Kingdom Hearts II, only this time, an orchestrated version of "Passion" is used as the background music. This shows some level of continuity planning for the sequel on Square-Enix's part. The letter also appears at the front of the game manual for Kingdom Hearts, again showing that maybe the letter is a sort of slogan verse for the series.
- A finer point about the letter is lost in the English translation of the game: before sending the letter off, Kairi only remembers that his name "starts with an S". Only after sending it does she remember his full name, Sora. In Japanese, the "Sora" means "Sky", so the final line of the letter "One Sky, One Destiny" would have jogged her memory after writing his name out. Unfortunately, making this connection clear in the English translation would be impossible.
- If one carefully examines the letter in the brief moment it is on screen, it can be seen that the word "starting" is misspelled as "stating."
