When Alexis came over, Natsumi was certain this was the right move.  Alexis had experience leading soldiers in battle.  Adventurers were a completely different lot, but knowing that someone among them had tactical knowledge would be somewhat comforting.  Alexis was also a hardass, which was good.  She had earned that right with the scars on her body.  Listening to Alexis' warnings intensified her resolve.  Natsumi had fought monsters before.  Her village was created to protect the region from them moving in from the North, and occasionally they would travel across the land to stop monsters wreaking havoc elsewhere.  But she had never been in a dungeon before.  The monsters would have a huge advantage knowing the terrain and choke points, plus the fact that the adventuring party would probably need torches to see.  They would need to be at their best to take on the monsters.  "I have had experience with fighting monsters before, but I am weary about fighting them on their grounds."  It was looking like time to go was swiftly approaching.  If they waited too much longer their excursion would require them to travel during nightfall, which was an unnecessary risk.
