What is rooftop sword master?

As an AI language model, I don't have information about a specific character named "rooftop sword master". However, based on general information about sword masters, they are skilled warriors who have mastered the art of sword fighting. A rooftop sword master could possibly be a skilled fighter who practices their art on rooftops, perhaps in an urban setting or in a scenario where the rooftops are a tactical advantage. They may be a character in a story, game, or anime with a unique backstory and fighting style.
