It really said something about their journey so far that even the newest people didn't bat an eye when a giant crab came up from the waters to try and eat them. Kanbaru's suddenly red attire was a more noteworthy occurrence, though she'd understand some parties being distracted. Seeing Thomas smothered by falling ass was just that funny.
With Akiko holding the crab in place by its own blood, it seemed unfair to slaughter the animal that didn't know what monsters it had provoked, yet such was the life of cave dwelling creatures. It would be far crueler to the ecosystem to allow such a foolish creature to continue it's genealogy when it was so lacking in survival instincts.
