Mushuro sighed mentally. The first person to speak up usually wasn't the [i]actual[/i] strongest person around unless their reply was just to attack. BUT! This person could be someone who turned out to know that and was doing it just to throw him off, or if nothing else he could start with this guy and fight his way up!

"O-kay! Comin' at ya! Let's see what you're made of already!"

Before he could start he noticed that his challenge had gathered an audience, although a more familiar one than he'd been expecting. "Oh hey! It's the Cap'n and Ms.No-fun! Did you guys show up to watch me kick this guy's butt? I'll make it look really cool! Watch!" 

With that he pretty much jumped directly at Bristlebane from the top of Gol D. Roger's execution scaffold, did a flip in the process and then swung both swords right at him from opposite directions. It wasn't much for subtlety and a normal person probably wouldn't have jumped from that height anyways let alone a kid, but Mushuro didn't usually bother much for things like 'tactics' or 'plans' or 'thinking' even though he'd been trained to be quite good at strategic, sneaky combat. Such things just didn't fit his image of a pirate, after all! Much better to jump off a high structure and do fancy flips as he attacked in mid-air.
