I dont like the fighter girl, her sense of justice is off. If you really have justice, you wont watch on the sidelines. Its the same as being an accomplice.

I neither dislike nor like her. But I'm guessing the only reason she's in that party is because is "the Hero's party" (That the hero himself is an ashole wasn't thought nor planned). And the reason she doesn't leave it might be because playing the hero and solving quests is the job of "the Hero party". Aside from magnus, there isn't any other group that dedicates to it for the sake of doing a good for the world.
I too like the merchant girl. I would lament if it turns into a Harem.

taking you up on that that she isn't a good person. Maybe, but not every person that left their house to do good on the world walk clean paths.
Sometimes there are people that take opportunities that initially seemed to fit in the plan to realize their dreams just to find out it was just a muddy swamp filled with wicked intent. when they're down on the dirt, is foolish to think on going back on you're steps just because they wanted the clean and tidy path (it doesn't exist btw). people just keep going forward until they find the chance to get out of the swamp or drown trying.
So, what I'm saying is, there is a big difference between recyclable trash and disposable waste. they're not the same.
It has a oneshot label!!
