Troll king is coordinating a championship in boxing for many trolls looking to become his private guards, and you're one of the candidates. You don't even understand why you really applies - likely only a temporary insanity, since this tournament is filled with the most powerful resources which you've ever seen. Punch them in their faces, and reveal the king that you're the person who needs to get his location at the king's protector. Knock-out different trolls, and eventually become the winner of the prestigious championship. Have fun.
