i feel like that might be part of the point. I haven't read the raws but usually a story like this would start with small dilemmas to eventually face bigger ones, such as where are the adults, and what happens after they graduate. It will be revealed eventually
Idk if you saw this or not but at the very end of the chapter these usually 1 question like yours that gets answered cuz some of them do answer the things like who teaches them, how they arrive, what happens to graduates, how their system works so I figure the more chapters we get the more questions get answered and author is most likely doing this on purpose making us the readers ask the questions as a way to draw us in and give a little mystery to the story i mean the same thing happens in other tv shows ex. Naruto who his dad was, itachi's backstory, who the orange swirl mask guy was
Ok, hold on. I'm on ch.6 rn, but I just had to stop and comment. I'm confused on how everything works. How are they learning?? Where are the adults??? Are there like cities or smth?? Do they not have parents??? How exactly are they taking care of themselves??? There's elementary kids, but the oldest ppl around are only high schoolers.
I'm not saying the story is bad, but the laws of the world is just confusing.
