Destiny's Embrace

Destiny's Embrace (デスティニープレイス) is the default form of Kairi's Keyblade and a Keychain for Aqua's and Riku's Keyblades, and appears in Kingdom Hearts II, Kingdom Hearts Birth by Sleep, and Kingdom Hearts 3D: Dream Drop Distance.

Kingdom Hearts Birth by Sleep
When Kairi is still a child living in the Radiant Garden, she is saved from a swarm of Unversed by Aqua. Kairi gives the Keyblade Master some flowers as thanks, rewarding her with the Keychain for the Destiny's Embrace.

Kingdom Hearts II
When Sora is being attcked by Heartless in the World that Never Was, Kairi is given the keyblade by Riku in order to help defeat the swarm of Heartless. Like Sora's Keyblade, this Keyblade is from the Realm of Light.

Kingdom Hearts 3D: Dream Drop Distance
When Sora is about to face Xemnas within the Sleeping World of The World That Never Was, he explains that the connected hearts of his friends are his power, and an image of Kairi wielding the Destiny's Embrace appears alongside all of his other friends.

Design
The Keyblade is round and curvaceous to the point of appearing harmless. One side of the hilt is formed in the shape of a breaking ocean wave, while the other is formed into a beige vine of sand that wraps around the shaft, which is colored to resemble a sunset. The vine connects to a bouquet of colorful flowers, which form the teeth of the Keyblade. A red silken keychain connects the hilt to the Paopu Fruit token, a recurring symbol of the bond between Sora and Kairi.
