"Adventurer job is to protect", right.
"I hate people who abandon the weak"
Whut? I know that the way they made her as a bait is seriously a bad thing. But if they simply left her behind because she cant run that fast,then i dont think its their fault to be honest. I mean everyone knows that adventuring is dangerous, every adventurer knows that their life is at risk at this job. So you cant expect people to risk their lives for the weak. The girl clearly knows that and yet she still decided to be an adventurer. So yeah, the fault lies in her decision on being an adventurer and going into something dangerous despite knowing that she lacks the ability.
