she didn't even notice he was more interested in her "other pendant owner". Also I can't help laughing at the "I just bought this pendant last month" XD
As Bak said, if Baki moved in for a kill, Baki would get ambushed.
It's an old trick that Musashi used in Retsu's fight.
The 2nd KO is different, there was no play dead trick. Mushashi was completely out cold, even got poked by Baki's sword
