It depends. The anime is in Japanese, right?
At most a day's delay as translators get to work.
They extend mental capacities of the pilot, thus seemingly causing more severe forms of PTSD and unhealthy ways of coping - but the same extension of mental capacities magically does not apply to dealing with PTSD and healthy ways of coping. Why?
They extend mental capabilities of pilot in everything regarding war, planning, math, physics and so on, but do not touch anything social, psychoogical and so on. Why?
Overall, isn't there a general power-up of pilot's mental capabilities involved? And if there is one, why it is applied only selectively? Is it inherent limitation of Cores or what, and if so, why?
Basically, philosophy.
Everything about the Valkyries, even the UN's own policies for handling its Valks, is designed to get more bodies with cores to throw at the Antagonists. Everything. Including its psychological support system.
This is understandable, they're in a war of extinction as far as they know. But it does mean that Valkyries are encouraged to think in hard data and better ways to crush the Antagonists before them. Social stuff? Don't need it for civilian interaction, Valks understand me. Psychology? Valks are combat troops, not support troops. Dealing with PTSD? Disassociate and get back on the line, there's Antagonists that need to die.
To deal with the social and psychological issues caused by the cores generally upgrading their wielders you need
time, time to think, time to talk, time to read and time to write. All time for Valkyries is already assigned. Anything that isn't (tangentially) useful in teaching concepts that you can use to kill Antagonists better and faster and more is not part of your expected schedule, so dump it and get ready to fight.
It's immensely unhealthy, this kind of mind set. At best it gets you soldier class, and given Valkyries and their morale position,
influential soldiers. Who do not think like normal people do while having access to the higher levels of power. The UN has probably realised this and would be trying to keep this from being a big problem, but UN High Command is still constrained by the war situation and politics.
Either the UN gets enough Valkyries to start rotating Valkyries into support roles and to figure out how to develop the psychological/moral side of Valkyries as healthily as the physical and the mental, the war ends soon in a victory and Valkyries can start with getting integrated with normals, or there's going to be an eventual take over by Valkyries simply because they
are better at everything that matters to them and have the power to make it stick between them. Only question is how bloody the revolution ends up being.
I just really want to see what Kandaraka's opinion on Anna and Durga is. Maybe next chap when She(?) and Coke zero are finally talking
During the spar between Anna and the rest of the flight Kandaraka remarked on Anna and Durga.
Said remark was basically 'this is bullshit.'
