I don't think it's random either. I definitely didn't expect it but I think the modern integration is pretty cool. It makes me feel like everything is not what it seems. It was also integrated in a way that still makes sense with the original plot. I think that a society of people flocked to the island to maybe "preserve the natural lifestyle" or get away from something and that definitely is something people do, so the addition isn't ridiculous. The island's isolation reminds me of AOT in a way.
exactly!! and imo i think there's more to the isolation than we know rn so its exciting to wait and see
the plot is sooo amazing are we kidding omg i dont think the modern age integration is random at all.. it all feels like it has purpose and it feels like the author is gradually introducing more and more real life problems. alto and elva's relationship is soooo cute too
