Hi all,

I am trying to recall a manga, where there were only a few children left in Japan due to low birth rate etc

The only thing i can remember is that they were attending a school(?) together.
Sorry if i cant provide more details, i just vaguely remembering reading about this before and it's killing me trying to remember what manga is that

many thanks!
🤢

Is that Akarui Sekai Keikaku?

probably Sakura Sakura (Morishige)

Many thanks!
that was it!
