Destiny's Embrace

Kairi's Keyblade was given to her by Riku in The World That Never Was in Kingdom Hearts II. Kairi's Keyblade is delicate looking, and sports a floral design. Kairi used this Keyblade to fight against the Heartless for one cutscene battle in The World That Never Was. Where it originally came from, how Riku got it and how Kairi is able to wield it are all unknown. Its keychain is a Paopu fruit. The Paopu is used several times to indicate the bond between her and Sora.

However, after she uses it once in The World That Never Was, this Keyblade is never seen again. It is unknown if it will reappear in any future installments of the series.

Trivia

 * The code to obtain Kairi's Keyblade for use in Kingdom Hearts 2 (US version. Codebreaker: 11CEF10C 000008BD)

Simply equip the Kingdom key and when you do, it will be replaced by Kairi's Keyblade. However, this keyblade does not make contact with enemies. When using this keyblade, using magic or going into drive forms will cause the game to freeze. Basically, this means this keyblade is only good for show.
