Kingdom Hearts begins with Sora's Dive to the Heart, which foreshadows the events that will soon take place, but soon progresses to Destiny Islands, where Sora lives with his two best friends, Riku and Kairi. The three friends seek to leave the islands to explore new worlds and have prepared a raft for this purpose. One night, the islands are attacked by darkness and shadow creatures. Sora seeks out his friends, finding Riku first; Riku disappears into darkness, curious about what it contains. Soon after, Sora obtains a mysterious weapon, the Keyblade, to defend himself. Using it to fend off the creatures, he heads for a secret cave, where he finds Kairi near a door. She turns to him, saying his name as the door behind her blows open. The ensuing blast of darkness sends Sora and Kairi both out of the cave. The islands are soon destroyed, and Sora is left adrift, Riku and Kairi's whereabouts unknown.
