All right. I'm trying to kill all the bosses in the Monster Arena. I have Yojimbo at full Overdrive (and so is Yuna).

I went here to see how to get him to use Zanmato, and there are like...twelve different ways and they all say "OMG THIS IS THE RIGHT WAY FOR SURE!!!"

Yeah.

Anyway, I've done about a dozen or so resets trying over and over again to get ol' Jimmy to do Zanmato, and he's being very stubborn about it.

Is there any truly good way to do it?
