"and how would anyone predict that the guy was not a normal human that can die when stabbed? That situation was impossible to predict"
simple, always cautious and prepare for the anything, if the stabbing doesn't work, fall back, not suddenly thrasing the enemy, surely even common soldiers know when stabbing the enemy yet they still alive, they gonna fall back and prepare for another attack....
this is FANTASY world, and they already know "PSEUDO-IMMORTAL" exist and how to fight it....
moreover those girls destined to fight against MONSTERS where normal logic doesn't apply, and some of those monsters is OP and has intelligence high enough to command Lower ranks monsters (thats why MC is special, since he can kill that monsters solo)
so stop using EARTH logic to Fantasy world where anything can happen....
"THere's literally no reason for the Main girl to freeze up, especially because she knows she is capable of doing it."
no reason? she literally never has friend before, she just a girl who finally got her first friend and care for someone beside her father, for her that feeling is new, and suddenly showing situation where her first friend gonna die?
just look at her expression, for stoic and kuudere to react like that showing she doesn't know how to handle those emotions, since she never see someone she cares on danger before, no matter how strong she is, she just a teenage girl, not a Cold hearted Soldiers.
and not how she raised? her Father want she lead normal life, not as soldier... thats why her Father always encourage her to makes friends and do peaceful school life...
her father is Soldier for his entire life, raising a child is hard for him, thats why she just look like her father, stoic and lack expression, but doesn't mean her father raising her to become cold hearted soldier...
