so the test for everyone else, was if the ace of the class could pass a test (though I suppose the nobles also had a test whether they would acknowledge an ace of lower birth and follow his orders). Seems legit.
"Thank god these demons just standing there looking threatening while I chase after idiot deserters, hold long-winded conversations and do next to no actual fighting."
@Wolfwhistler that is why the nobles kinda had it (following orders from a commoner) as a test. Everyone else already had a solid subordination to the ace, making the test for them be only whether the ace would retreat.
Girl1:"MC only you can be commander! Please give the commands!"
MC:"Work together!"
MC:"Retreat!"
Girl2: "You did a great job MC! the best leader since Alexander the Great"
