LMAO, they actually referenced the thing as not a monster but as just free flying items. Very gamer-like mindset. Or robber, in this world. From a different perspective they're like robbers roughing up someone: "Now cough up that book!!"
I wonder if that scythe would end up in Hilde's possession? It was a curious choice that she ended up with a scythe after selling her sword. Surely it's not a coincidence?
