I'm back! Although I gotta say, almost nothing happened .... And that I don't know if YukiHana would go to the boss fight I think she would be scared to
I'm not necessarily thinking of better quest rewards, she's just a bit of a coward cautious individual, so would probably avoid the fight if she found an excuse.
I'm sure Paka could convince them to go. After all, he has the howl ability. He could bribe them and say they need more people, and he will draw the monsters to him
