I'm at the karate studio. My Sensei is there. Two young malevolent Asian men show up and challenge Sensei to a fight. He agrees. But then the guys say they want to use weapons. Since he already agreed, Sensei doesn't renege. I was confident he would beat them before. But now with the weapons, I'm worried for him.
I see the weapon he will use. It's a double broadsword whose blades are thin and lightweight. Each blade is uniquely shaped, as if a sai had been completely flattened.
