After wandering, jobless, he/she sees an official notice for recruiting adventurers, posted by King Tristan 3rd. The notice says, 'You can have different types of jobs depending on your effort'. He/She picks his/her body up, the body that usually doesn't move, and steps into the world of adventure.
Without money, and just the Knife and Cotton Shirt given by the King, he/she sets out to the tough battle against monsters.
Their only worthy skill is their determination to achieve something with every movement of their knife.
