Rea

You have begun exploring a C-Rank dungeon which was recently closed for emergency clearing; it had begun overflowing with B and A Rank entities which needed to be immediately suppressed. After about an hour of exploration you've gone quite deep into the dungeon, but haven't found much other than already-dead monsters. Suddenly, an explosion rocks the walls around you, and you turn the corner to find a strange-looking woman. She's standing in front of a decimated pile of monster corpses.
