They returned earlier than Leo had expected but well, he couldn't expect less from an S-class such as Devon.
He was never weak to begin with and the monsters in the red zone should be a piece of cake to him.
Just like butchering real livestock, Leo got his hands dirty and skinned the red wolf of its skin right on the kitchen counter, before cutting its flesh into bits.
The kitchen was a bloody mess by the time he was done but he wasn't concerned about that. They could just clean up after he was done.
Thankfully, the monster wasn't infected with demon blood so it was pretty much edible after getting rid of the poison that humans could not consume.
Leo had only asked for a chunk but since they got him the entire red wolf, he decided to leave the rest in the refrigerator for another time when he needed to appease Alice.
