Luna suddenly caught sight of something on the edge of her vision, and Luna turned to her side in surprise to see that Mark was already crouching on the branch beside her. When did he get here?

Mark had been helping out an S-rank in the forest who was fighting a high-level calamity. There were a lot of civilians moving towards the hotel, so Mark had to help the S-rank to make sure that the calamity was killed as quickly as possible so the civilians wouldn't be harmed while moving through the forest.

Luna noticed that Mark was now wearing a face mask that she had never seen him wear before. It was made from a black carbon-fiber hybrid material with a metallic gleam, and there were two circular filters on each side of the mask that released a puff of white air every time Mark released a deep breath.
