Rouge no Densetsu

A long time ago, a legendary hero defeated an evil dragon. He wore a magical bracelet that protected him during the battle. Years passed, and the memories of his heroic deeds, even his name, have faded away from people's minds. But a young girl named Rouge, who trains regularly in the art of sword-fighting, still dreams about a real hero - more precisely, imagines that she will marry one. [Edited from Mobygames]
