Swordsman event

[Xehh II]

I started a new game as Imagawa and I finally got the swordsman guy, it took 3 defensive battles against Takeda.

Thanks but after I eliminated Takeda I was displaced to my Kyushu provinces by the Oda/Hojo alliance, Hojo took over Takeda provinces when I defeated them.
I started a vicious war against Shimazu to stop them defeating the Mori, my allies.
So at the point in my game, I control Kyushu and half of Shikoku, the Shimazu still stubbornly hold the other half while my Mori allies are battling the Oda for Kyoto.
I don't know what the Hojo and Uesugi are doing but I know that Oda and Hojo broke their alliance and started fighting each other soon after conquering my main provinces.

as i recall the fastest way to do it was as Pape-san suggested- get your hamamato to do some slaughtering
