In Kingdom Hearts II, Kairi wrote a letter to Sora. She wrote it the day before Roxas made contact with her. 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."
- "Kono sekai no dokoka ni iru anata e.
- Subete no kanashimi ga kieru youni toka.
- Subete no kokoro ga tsunagaru youni toka.
- Negai dake dewa todokanai omoi wo kanaeru tame ni.
- Watashi wa susumou to omote imasu.
- Atarashii tabidachi wa igai ni kantan na koto kamoshirenai.
- Moshikashitara sore ha mou hajimatte iru no kamoshirenai.
- Kono sora ga tsunagu sekai de.
- Tadoritsuku basho wa issho datou —
- Shinjite imasu."
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.
