All Keyblade wielders seems odd. I only remember Sora being linked to her that hway (apart maybe from Donald and Goofy but even for them, it's a big maybe). And even then, if Imaginym's post is write, then it's not really immortality, more like some sort of Reality Warping type of thing.
And even then, not intentional; Sora didn't know about the consequences, & it seemed to be more a consequence of him abusing the Power of Waking, so much so, that reality rewrote itself. Rather than Sora knowingly & willingly try to rewind time or something.
He was seemingly reviving the others, but other than the backlash from reality....
Thinking on it, another reason the Type 8 may not apply is Kairi is more connected to Sora than most other characters; Her Heart took safety deliberately in him for most of KH1, & she openly said she'd protect him.
Namine might get in on it, as she was a Star in The Final World, & IIRC, stated that as long as Kairi's still around, she'll still be. But Namine was a Star in TFW when she said that, so not exactly ideal.
During KH2, Roxas connected to Kairi's Heart, when, IIRC, Kairi was trying to reach out to Sora (As memories of him were returning to him with starting to awaken) & Roxas's Heart responded.
Given that he (& Namine) are a consequence of Kairi & Sora's Heart exiting Kairi's body, they MIGHT have a similar connection, but I think that's a stretch, especially when Kairi's vowed to protect Sora a lot, & barely knew Roxas existed before he came to fight Saix.
Lastly, Xion is largely made of Sora's memories of Kairi, but that's not the same connection as originating from Kairi's Heart exiting Sora's body, nor like being the Special Nobody of a Princess of Heart.
The biggest other stretch for a supernatural connection would be Aqua, as Aqua unintentionally, unknowingly bequeathed a Keyblade to a young Kairi during the events of BBS at Radiant Garden.
Sora SORT OF has Type 8 Immortality, but I'm not really sure about most others. And his was that he died, went to The Final World, & Kairi was able to ensure he had a form, despite lacking a body AND lacking a Heart at the time, which he used to gather his conceptually scattered self.
This & him returning to the real world MIGHT have been before the reality rewrite, but I'm not sure. Might need Ultimania consultation.
