Riku can use a Keyblade as he is Terra's chosen processor Kairi can as she is a Princess of Light.
No.
Riku is from Destiny Islands. That is also where Sora and Kairi are from.
Of course. :p.
Yes
no
Did you meant Riku? Riku is Sora's best friend. He wanted to make sure Riku and Kairi are safe.
if your talking about after sora loses riku and kairi ull find him in hollaw bastion, he quetion goofy and donalds apperance and hate them for '' taking his freind'' , then disappear and reappear in the whale ate gepeto and pinnochio.
Unlike Riku, Sora and Kairi didn't have darkness laid dormant in their hearts. Riku needed the blindfold to retain the darkness in his heart that Ansem had created from Kingdom Hearts 1.
Sora, Kairi, Riku, Donald, and Goofy!
Sora.
Kairi is a close friend of Sora and Riku, she gets lost in the first game by the darkness, as Riku captures her and keeps her away from Sora, but at the end of the first KH game, Sora saves her and Riku, Riku goes into the Door To Darkness with Mickey while Kairi goes back to her home, Destiny Island. In the second game she meets Sora again at about close to the end of the game
