What should I do? Obviously, I should just press on with my own theory and increase the amount of confusion here xD
This is the rough timeline of my theory:
common route (parallel universes already exist on earth) -> pre-moon routes + parallel universe events not shown in game -> death of earth in ALL parallel universes + Aurora remnants travel to the moon -> Aurora settles on moon ‘soil’ and multiplies a bit -> ‘garden’ is formed -> moon route + earth ‘soil’ recovers slowly -> end of moon route (Aurora travels back to earth, moon Kagari reverts into a flower) + moon ‘soil’ is exhausted + earth ‘soil’ recovered enough for one more try -> Terra
What’s the ‘main problem’ in the plot of Rewrite? It’s the fact that the amount of Aurora on earth keeps decreasing due to human behavior. The earth usually solves that problem by means of ‘salvation’, followed by ‘re-evolution’. Only this time around, it would be no use, because there is not enough Aurora for a re-evolution. And the only ones even remotely aware of the problem, Gaia and Guardian, are too busy killing each-other off instead of working on a solution.
As the game begins, multiple parallel universes already exist. Parallel universes are formed when the density of aurora reaches a certain point. Also, the pre-moon routes took place on earth. Which means: There must have been a time when the the amount of Aurora on earth was really high, so parallel universes were formed. It would make no sense for parallel universes to be created at any time after the pre-moon routes, because an amount of Aurora capable of creating parallel universes would already solve the main problem of Aurora shortage.
As I mentioned before, all parallel universes ultimately ended the same way:
Either all creatures are eradicated via salvation and there’s nobody home to produce new aurora, thus it runs out and the planet dies.
Or salvation doesn’t happen, allowing humans to keep wasting aurora at a fast pace, thus it runs out and the planet dies.
We can assume that neither the survivors of Shizuru’s route, nor those of Akane’s route could manage to save the earth in the end.
In the end, all life ceased to be, and then the earth became a poisonous hell, hostile to all life, as predicted in Lucia’s route. Only Lucia would have been capable of surviving in that environment. Aurora can’t thrive here.
The remaining aurora traveled to the moon and took root there. It multiplied a bit and the garden was formed. Moon Kagari is now working on a solution with two things in mind:
- Eventually, the ‘soil’ of the moon will dry up and it won’t be able to sustain the Aurora
- Eventually, the ‘soil’ of the earth will recover enough for one last attempt at evolution
Therefore, Kagari is trying to find way to make this last evolution succeed. She needs a future where the creatures inhabiting the earth would not go extinct eventually.
Moon Kotarou comes into being when different aurora parts of his alternate universe versions come together. I am implying that all versioins of Kotarou were real. The aurora remnants of those different versions of Kotarou came together, forming the ultimate Kotarou, Moon Kotarou. He has the memories and skills of all his past versions. He looks older than most of them, because Akane route Kotarou is also in the mix.
Those aurora remnants, containing ‘memories’ of Kotarou’s body and mind, must’ve come from somewhere. Somewhere real. If the pre-moon routes weren’t parallel universes, but were instead, as others theorized, just simulations in moon Kagari’s theory, there would be no point in mentioning aurora’s property of forming parallel universes in cases of high density. Therefore, I can’t accept theories that assume that all the pre-moon routes ‘didn’t really happen’.
By incorporating moon Kotarou’s little note in her theory, moon Kagari manages to find a way for life to continue thriving before running out of time. All the aurora, except for moon Kagari, is sent back to earth where life is formed once again, following moon Kagari’s theory.
When the time of Kotarou’s childhood is reached, Terra route begins. There are no parallel universes this time, since there’s not enough aurora to create those.
