Neat! I spotted the gacha rules in the IC OP. As attractive as the beginners' banners are, I think Schnupfen would recommend pulling on the standard banner because a variety of monsters, equipment, and dungeon elements sounds best right now rather than investing into one branch.

Although our frontline is effectively one goblin and some rats, Schnupfen's in a unique position if this adventurer really just has a sword, in that neither of them can effectively hurt each other. He'll probably volunteer to go ahead to try and delay the boy by spooking and misdirecting him (as much as possible, since Burger mentioned he wouldn't be that affected by appearances either) in order to give the others time to gacha and make the most of it.
