She was afraid if they can kill that many wolves mercilessly, then what's a human before them? Just another animal that works on two legs instead of four!
She was putting up a tough front on the outside but was devastated from the inside. When the day came to an end, she went inside her camp and asked the others not to disturb her, not even for dinner. The others understood what she was going through. It was her first time to witness something like killing animals, and allowed her some time alone.
All she could do inside was to sob to her heart's content and let it out in one go. When she heard the sound of an explosion, she wiped her tears and rushed out of her camp. The others also got alerted and hurried out from their sleeping bags.
"Miss. Rin, please stay on standby," ordered Simon, the leader of the group, and afterward headed towards the source of that sound, along with his other members.
