what the hell was this ending? I liked the alternate universe/time traveling kind of thing before, but this one felt a little pointless.
Suddenly every conflict created by the black goat arrival was a paradox that was erased just as cheaply. Black Goat(Machine God) was sent to the past and sets in motion the machinations towards the birth of Son of God leading to the merge/destruction of the human race, which created the Machine God to be sent to the past in the first place. So why are we seeing this, if its a self creating paradox that ended itself when Son of God was killed? Its not like Midori-chan went through it all and came back.
Did i miss something, maybe was that alternate universe and merge of humanity was what gave birth to the extraneous? So those extraneous constantly travel to the past to create the conditions that birthed them in the first place?(and maybe that could cause the entropy thingy if hitsuji dint intervene) Or are they simply the burden of the unfortunate as was stated before, but well on the final timeline they did look different then portrayed in the past. Idk, i guess i read through it way too fast (×̯×)
to run with the entropy angle, it could be that was hitsuji's plan all along. the extraneous are constantly coming from the future to take out hitsuji, but by doing so they are adding mass into that universe.which would help slow down the rate that entropy increases or even reverse the direction in that universe.
but really its most likely the events in the final chapter were meant to parallel Jesus Christ as the death of the Son of God (in Scape-God, that's You) is what saves humanity. the time travel stuff is just a convenient way for the author to explain how exactly the world was saved.
