Kairi used this Keyblade to fight against the Heartless for one battle in The World That Never Was. Where it came from, how Riku got it and how Kairi is able to wield it are all unknown. It's keychain is a Paopu fruit, similar to her charm on Oathkeeper. The Paopu is used several times to indicate the bond between her and Sora.

However after this moment Kairi's Keyblade is never seen again. It is unknown if it will reappear in any future installments of the series.
