Destiny's Embrace.
Duh everybody knows that sora sacerificed himself to save Kairi's heart, thus creating Roxas and Namine. Then Sora turns into sora-heartless and kairi saves him so that sora gets his hearts back. And that is why.
You can't give Riku a keyblade, he just gets it in Kingdom Hearts 1 when he goes in the Door To Darkness. AA: Riku is just a world specific ally so you cant change his weapon
sora as many keyblades but the first one he ever gets in both kingdom hearts 1 and 2 is the Kingdom Key it's the weakest, most basic keyblade in the game.
Its Kingdom Hearts 368 days/2 Its harder than Kingdom hearts 2 but its fun. Especially the ending (spoiler! Spoiler!) Roxas gets a second keyblade and fights Riku Roxas gets defeated and its game over
"Ansem", who at this time looks like Riku, told Sora that the way to awaken Kairi's heart was to stab his chest with the Darkness Keyblade, which he does. The Darkness Keyblade turns Sora into a heartless, but releases Kairi's heart, which shows why at the last second she gets up and runs to the disappearing Sora.
His name is Ventus and he is frozen (not killed!) by Master Xehanort in the Keyblade Graveyard.
Riku gets the Darkness Keyblade in Kingdom Hearts, made purely out of his Darkness. He loses ability to wield a Keyblade for a while, then he gets the Soul Eater Keyblade in either the beginning of Chain of Memories or the end of Kingdom Hearts, I'm not sure which. He get's Way To The Dawn after choosing the Path To Dawn at the end of CoM, or RE: CoM. Those are his only three keyblades.
Xion, the imperfect clone of Sora, gets eliminated by Roxas on Day 357 Tears in Kingdom Hearts 358/2 Days, because she wanted to return Sora's memories of Kairi back to Sora.
It depends on which point you are at in which game. Kairi (with only one "r" if you will) in Kingdom Hearts 2--I hope that's what you're talking about because I have not finished Kingdom Hearts 1--ventures to Twilight Town but gets kidnapped by Axel, so your hopes in finding her there are none...way later in the game the Twilight Town group that helps you (Hayner, Pence, and Olette) are at the Old Mansion beyond the forest, thinking of an alternate Twilight Town portal in it. You find it and once you get through to the Castle That Never Was--I like to call it the "Nobody Castle"--after a few battles you get to where you fight Xigbar, Organization 13's number 2. Once you fight him there's a video where you see Kairi again and meet up with her and Riku and you travel the rest of the way together, even though almost every battle after that you get separated from Kairi. I don't know what you obtain once you meet with them, but I think it's that Keyblade. Just keep traveling through the castle to Xigbar, even though it is VERY VERY VERY VERY VERY difficult to beat him. Good luck, though! Hope this helps!
he gets absorbed it sora
Kingdom Hearts Birth by Sleep is basically the most important game IN the saga. It explains how sora became keyblade master and why riku chose to go into darkness. The major thing that happens is at the end in the secret ending. Ventus goes into young Sora's heart. This is why sora EVER became a keyblade wielder. Also, Roxas and Ventus look identical. This is because when Ventus went into Sora's heart, he became a part of Sora. When Sora sacrificed himself for Kiari in Kingdom Hearts 1, that formed a nobody, Roxas. Part of Ventus went into that nobody, so Ventus and Roxas look just alike. Aside from all of that, the other major thing is that Terra gives Riku the power of darkness at a young age. So in KH1 when Sora gets to weild the keyblade, Riku gets to control darkness.
In the first Kingdom Hearts, none of Riku's Keyblades are obtainable.Riku uses many keyblades throughout Kingdom Hearts 2, though. He is first seen with the Soul Eater Keyblade, which cannot be obtained. He is then seen with the OblivionKeyblade, which he gives to you at The World That Never Was, right before entering the castle. The last keyblade he is seen with is the Way To The Dawn Keyblade, which also cannot be obtained.
