The key to the door to the world of darkness in the light of the heart, got it memorized?

I think all of them, honestly.

Knock knock.
Who's there?

Has nobody done, like, an analysis of the script to check this kind of thing? I'd be really curious to see what the actual answer is.

I’m voting for memorized. Just because.

Good ol’ D A R K N E S S S S

Darkness, Sora, Riku, Kairi, Ansem, Keyblade, or Light.

If it's not "darkness", it's definitely "heart".

Sora, Donald, Goofy, Darkness.

 

Peace!

SORA 
DONALD
AND GOOFY

Darkness within darkness within darkness within darkness within darkness within darkness within darkness within darkness within darkness....

(If we'd include stuff like Riku saying "DARKNESS!" everytime he transforms into Dark form in a battle in Chain of Memories, then yeah definitly darkness!)

Say DARKNESS in a Billy Zane voice LOL

There only ever one answer...
