Demon Slayers is a group who hired and sworn to kill demons.
The group let off a somewhat odd aura. It was dark—a total and complete blackness that left room for nothing else. They were dressed for the highest amount of maneuverability in attire that seemed fortified by darkness itself, and their mouths were hidden by jet-black cloths. The group’s members were almost entirely Beast People who were taught by its leader. They raced by like a dark wind, cutting down passing monsters with incredible speed.
