Hunters
Usually, there would be a few quests with the goal of subjugating demons on the bulletin board, however, the number of such quests was gradually reduced a while ago.
Students and people, in general, believe that it was due to the emergence of a new group called Hunters.
Hunters was a group of a few individuals whose strength rivaled the Grand Order at the least. The small group tended to move independently and follow their motive to actively purge any threats, especially demons, which in turn, could indeed be the reason for the lack of demon subjugation quests.
At the time the Hunters were announced, it caused a huge uproar everywhere mainly because Olivia Rostanta, who was formerly the captain of the Grand Order, joined the group. Many believed that she started that group and that she would once again be the leader but in an interview, Olivia revealed that it was not her idea.
