Persistent Alberto

Lore
Alberto had suffered many defeats in his life, but he was proud that he had never lost to the same opponent twice. This held true even in the arena, where nearly all of the losers perished. Alberto battled on with raw tenacity that appeared clumsy to those watching him. But before long, the cheers in support of Alberto grew louder than those for any other fighter.
