That Yojimbo is kinda weird, actually. Some times I give him just 1 gil, and he uses Wakizashi, some other times I give him 300 and Daigoro attacks instead. And the otehr day I paid him all of my freaking money and the bastard made Daigoro attack as well (I don't remember the amount but I know it was hundreds of thousands, if not millions)
and I have never actually seen his most powerful technique either.
but anyways, if it's just Daigoro, the damage will always be at least 9999
