The question is, was the poster originally drawn independently for each panel it appeared or did they copy-paste across them? (Aside from the instances where it's obviously different.)
Kind of a flaccid ending, especially after it had enough time to wear its premise pretty thin. Just status quo while saying "They'll get together in the future!" is lame. There's not even a light novel in play here, this is the story in its entirety. Was really hoping for something more, but oh...
Jesus FUCK this manga is weird even for body horror. I guess the story is that living humans are turned into some kind of foundation for the island, and eventually become those fleshy cocoons?
