Wonderful ending, loved it.
There's a fair degree of magic realism into it too, with the disappearance of the machine and with how it felt like they ended up looping back into the first time they entered the new world, but overall I don't think it's too important to dwell on that since it feels more like an aesthetic choice to represent what they were talking about souls and bodies and stuff.
Overall it's definitely not a series to think to deep about it, but just an incredibly beautiful ride, would love for Yoshitomi Akihito to make more works like this since their way of drawing weird sci-fi landscapes has to be one of my favourites of all time.
Thanks again for the month of daily bliss team <3
