After the end of the battle, everybody present had been exhausted. They had battled against more than 30 Tier IV monsters, and even though they hadn't been as strong as the average high-grade and peak Tier IV monsters, they were still a force to be reckoned with.
Reign had fought a hard battle against the suit, and even though he had healed his injuries with the light manipulation ability, he was exhausted mentally and physically. Even walking was tiresome for him, and the others fared no better.
Since they had defeated the monsters, and the fog had scattered, there was nothing they needed to fear now, so they could easily rest in the giant ship.
Upon killing Nearsch, the fog started scattering, and thanks to that, the power of the monsters lessened, so Wolf and the others had an easier time defeating them in the end.
