So I’ve searched some discussion forums about the ending and literally everyone is a bit confused as it’s pretty vague and open ended. So I’ll let you know what’s pretty well agreed on and then where it’s more open to interpretation. So just about what everyone agrees on is the end with the new guy/girl is meant as a stand in for Class Rep and Haru basically implying they are going to repeat the cycle. The sort of history repeats itself theme the Japanese seem to love. Kind of like an Attack on Titan ending.
Now where it is vague is what exactly happens to Class Rep and Haru. Here’s the following theories.
1) The new humans are the two’s descendants and new guy/girl are them reincarnated
2) The new humans are the two’s descendants, but they are still alive watching over things in the space station and new guy/girl are just next people in the cycle
3) New humans have nothing to do with the two they are just aliens who moved in, but otherwise the same as #2 above
4) The new girl is their daughter and the “work” they are moving for is to go to another earth and repeat the process
Wow that is such an unsatisfactory ending then. Not going to lie I thought it meant the girl was a different type of alien and the story would repeat in that way. Also I don't get the "new humans" they litteraly look the same what was the point in killing off the old humans? Litteraly could've just assimilated.
Yeah, I agree not a great ending. That being said the “new humans” did not start off human-like. Their opinion of humanity was that they were primitive and barbaric. Like if we wanted to set up a town where there were a lot of large wild monkeys known for being violent to humans we’d send people in to hunt the monkeys first before moving in. We do it all the time with a variety of species around the world. Of course, we also have nature preserves and things, but I guess they didn’t consider that an option. Anyway, it’s implied they started closer to Haru’s alien form and decidedly non-human, but coming in contact with humanity’s ruins and left over culture made them start to take those things on and after centuries or even thousands of years they became the so called “new humans”. By the time we see any “new humans” it’s implied it’s been a couple thousand years
Imma need a mega nerd to explain chapter 23 to me
