1: I don’t get why there are two of Kagari. How did that happen? Are they completely separate or do they have a shared mind?
That’s pretty much up to your interpretation if they’re separate entities or not.
2: Why does Salvation occur? I understand what qualifies for good memories (IE all of humanity joining together to work towards new innovations/a new future), but what makes a world bad enough to need a Salvation? Does Kagari dislike having to resort to Salvation or not? In Moon she seemed blase about it, yet in Terra she was very reluctant.
Good memories is anything that leads to the survival and spread of Aurora(see the Moon topic for more information). Salvation is originally a fail safe but it consumes so much energy that it’s actually a bad thing for the Earth in the current situation. Therefore, any time Salvation is triggered means the Earth and humanity is doomed. Salvation is an automatic event that is triggered when the key fails to see any chances of good memories happening.
