Spoiler for speculation:

Interesting. I think this made my hypothesis, wherein Kanade was part, or even leader, of an SSS-like group (Gen. 0 insurgents) which had gone much much further than the current SSS in terms of technology and making the afterlife chaotic, look a little less contrived. They may had started an all-out war against the NPCs at one point, realized that there is no God and that rebelling is ultimately useless, and then proceeded to face their regrets in life and move on / disappear. Kanade chose to stay behind to ensure that history would not repeat itself, and that newcomers will live a peaceful afterlife before reincarnation/ascension.

Spoiler for Ep06 preview:

And it is possible that Naoi also chose to stay behind with her.
