tavrobel i wasnt saying that 14 was a great omnipowerful age were you are invincible im simply saying that when you are young you would be all afraid and probably die. and the only reason that the keyblade wouldnt pick riku is because the darkness hadnt touched their world yet . when it was touched by darkness riku gave into darkness so there is no way that the keyblade would work with the darkness. now near the end of kingdom hearts 1 sora found out that riku was really meant to have the keyblade so he got depressed and his heart got weak so riku easily took the keyblade and the keyblade saw sora as weak but then sora took it back becuz he believed in the heart again.
yes i know there are more than one keyblade but since we know that tyhe keyblade chooses who to stay with maybe tthe keyblade's all came from one ultimate keyblade and can replicate itself and thats why when sora goes valor he has 2 keyblades (yeah i know there are more but why babble)
and the keyblade did leave sora completely and later he got it back so nyaaaaah
