Where does it say Sora has to rescue them?

[Igloo9]

I heard people saying that in the Coded ending, it is revealed that Sora has to save Roxas, Xion, Axel, Terra, Aqua, and Ven.

I just watched the ending to Coded and Namine didn't say that. She just said, Sora had to save some people, 2 of which he already met. That's it.

Can someone tell me where it says he has to save all of them?

Cause Sora is connected to everyone that need to be saved.

Sora isn't connected to Axel, Terra, or Aqua.

He's only connected to Xion, Ven and Roxas.

When Sora battled with Axel inbetween and Betwix Axel came in contact Sora's hearts which awoken Roxas sleeping with in that triggered "Dive into the heart" battle

Terra selected Riku to be a a weilder of the Keyblade who's heart is connected to Sora.

Aqua Selected Kairi as a weilder who was protected by a spell that would send her to the Hero of light who is Sora whos heart is connected with hers as well.

It says so before the cutscene. Try reading a walkthrough.

Wow, that's going way too fucking far. I mean, I like it, I'm glad. It sounds cool and I'm glad all of those characters will (hopefully) be saved, but damn, that's stretching it.

(Hazy images of Roxas and Axel appear suspended in the air.)

Namine: The hidden truth... This was hidden deep down at the bottom of your heart, Sora. It's not really your memory, Sora, but it is connected to you.

(The images fade out. New images appear, of Xion and Namine.)

Sora: Namine, this is you... And, who is that? I don't think I know her, but she seems familiar... So lonely. Is this the Torment?
Namine: They're all waiting for you, Sora. You are the only one who can free them from their torment.

And because of the ending movie, we know that list also includes Ven, Aqua and Terra.
