Kingdom Hearts Story Recap
Kingdom Hearts 1
The Heartless
If you’re unfamiliar with the Heartless, they serve as the main antagonists of the entire series. A Heartless is created whenever a person’s heart is stolen by Darkness, and they’re malevolent beings hellbent on stealing more hearts.
If a Heartless is slain by the Keyblade, and only by the Keyblade, it will release the heart they’ve stolen to reunite with the body.
The Seven Princesses of Heart
The Seven Princesses of Heart are a central idea to Kingdom Hearts, and they comprise of Disney princesses like Cinderella and Aurora, as well as Kairi.
These Princesses’ hearts are comprised of nothing but light, and they hold absolute power to protect from Darkness, as well as open the final Keyhole in Hollow Bastion, which supposedly holds power over the entire universe.
Sora Has Kairi’s Heart, and Becomes a Heartless
At the tail-end of the game, we learn that Sora has been housing Kairi’s heart this whole time, keeping it safe. In order to revive Kairi, Sora takes Riku’s Keyblade and unlocks Kairi’s heart and his own. This results in Kairi awakening, and Sora himself turning into a Heartless.
Of course, this event also resulted in the birth of both Namine and Roxas, Kairi and Sora’s Nobodies. By finding Kairi again, Sora is able to return to his human form, and he’s the only person in history, besides Xehanort, that has been able to do this.
Closing Kingdom Hearts and Defeating Ansem
Sora, Donald, and Goofy defeat Ansem, the Heartless that has been possessing Riku.
They discover the door to Kingdom Hearts, and end up defeating Ansem with the light inside, but in order to keep the Dark Realm from seeping into the outside world, Riku and Mickey have to seal the door from the inside, thus dooming themselves into the Dark Realm.
All of the world hearts that were taken by the Heartless are freed, and the world are restored to their former state.
