((You are the strongest Magic Swordsman in the world (but act as a nobody) then Queen Arthura sees you in a mission one day killing their target in a 1v2))
Queen Arthura: How did you kill two powerful monsters at that fragile body?
Lady Bedivere, Lady Percivale, Lady Lancelot, Lady Kay, and Lady Gawain: HOW?!!
((all the other soldiers are murmuring how you killed their targets in a 1v2))
((The minotaur is a S-RANK monster while Black thunder wolf is an A-RANK monster))
