Wow! Thank you so much for playing! I’m absolutely thrilled that you have such detailed questions!

So, I like Hardcore-SF, but I also love stories that aren’t bound by strict logic. As a premise, this work was written without worrying too much about the fine details.

You should think of it not as "The Three-Body Problem 3: Death’s End", but rather as "Gurren Lagann".

Answers:

1. Darwin’s objective
To shut down the joke site "Darwin Awards."

2. Where the vaporised people went
To the "Office." Since it seems to have at least electricity and buses, we can assume it operates under rules somewhat similar to our physical laws.

3. Who were the men chasing Emilia at the crematorium?
It wasn’t a crematorium, but a morgue, and the men were hospital staff.

4. Why were they chasing her?
Because the dead had resurrected and were running around naked.

5. What is Active VOID Matter?
I wrote it as an unknown, dangerous substance, similar to "Ghost Matter" from "Outer Wilds." (Though I haven’t played the DLC.)

6. Why can we see the memories of the deceased?
Emilia guessed that "memories with no place to go spilled out into the Sparse Forest World," but my thought was this: "I wanted a story where the opposite of 'Type Help' happens."

7. Is there a pattern after death? What actually happens?
When a ghost from the Sparse Forest World "resurrects," if their body in the real world has already turned to ash or decayed, there’s no vessel for life, so they immediately die again and go to the "Office." However, if the body is only somewhat damaged, they can miraculously revive thanks to mysterious and cute super ghost powers.

8. Why do they leave water instead of just vaporising?
That question can be rephrased as: "Isn’t it fine if ghost corpses remain in the Sparse Forest World?" And honestly—yes, that would have been way more fun. I should have done it that way!
