couldn't the representatives get their own personal IS after they pass the academy?
I mean it feels like it would be more sensible and safe that way even though Charlotte, Rin, Cecilia and Laura earned it physically and most likely having connections entrusting armed to the teeth robot suits to them while they’re still pretty young and don’t know any better feels extremely careless and foolish especially when it's obvious that they haven't earned it morally and their behavior is violent, undisciplined and rotten so their countries governments really should have know that there’s a 90% chance that there's absolutely no way they're gonna be good representives and are going to do more harm than good.
I think the smarter play would have been to just send them to the academy without an personal IS to sharpen their knowledge more and help them become more humble and responsible and wait until after they graduate to give them the suits. with Houki it makes sense seeing as how Tabane doesn’t care about anything especially ethics and thinks she can do whatever she wants simply because she can and know that almost nobody can do anything about it.
