What is the reason for the Keyblade choosing Sora

It's a heart thing i suppose. sora has a strong heart, he has bravery, hes a great friend, all the thing the keyblade searches for. his soul fits the keyblade you can say.


ITS A GAME NOBODY KNOWS WHY A KEYBLADE WOULD CHOOSE A KID. ONLY THE MAKERS OF THE GAME KNOW WHY

Actualy theres a reason why, way before kingdom hearts, there existed three other keybladers, but the one named ventus was killed, and his heart transfered to sora, which allowed sora to wield a keyblade.. plus the names have a resemblance, sora which means sky and ventus which means wind..
