@sathariel HxH is different for two reasons. First, the teachers do not care if you die. It's your decision to take the exams and you take all the risk. Second, not everyone taking them is a good person. They're testing your ability to stay alive and kill good, not your ability to serve justice.
Granted, I've not really got past the actual exam arc yet.
I just get a vibe that strongly differs from Naruto or BNHA cuz the age group is different (hunters are mostly adults) and it's not really a school.
