Being sleep deprived & only eating the ration you brought is common in a dungeon. It's better to know whether someone can handle it or not in a controlled environment with the instructor present.
If they can't handle it, then it's better for them to not enter a dungeon at all.
Yes, its harsh training. But that's part & parcel of being a hunter
It's no wonder the other hunters hate training if this is the type of training they get, doing all that stuff while massively sleep deprived would count as a form of torture. I honestly hope it blows up in the trainers face when they are too exhausted and it ends up putting them in to a dangerous situation!
Also thinking that she can ask for food after doing all that stuff to to our MC, I'd tell her to go eat dirt!
