Pugilist Weapon Mastery

There was a girl we called Roma who made a living knocking men on their asses in the ring. She didn’t look like much, but she was fast as a spooked wanyūdō and clever with her punches. Flowed like a river and then “BAP BAP BANG”, two jabs, an uppercut, and the other guy was down. Nobody could take her in a fair fight. Course, lots of fellas don’t like looking foolish, and some would come looking for revenge later, armed to the teeth. It’s a funny thing; turns out nobody could take her in an unfair fight, either.
