ok, in a glance, this looks very interesting.
another retry of Promised Neverland, maybe?
or manga version of The Island movie.
But then... for now at least... some really doesn't make sense to me.
If they're already so hi-tech that they already have a contained, fully-monitored island enclosed inside an individual space dome,
why would it need to be a restricted area within that island?
It would make sense if it is restricted because of the dome's boundary like in The Truman Show.
Why would you risk placing some "sensitive" area so close to the "experiment (?)" area if you have another dome to place that?
