With a blood-curdling scream, you leap on to the stage, seizing the daimyo's fallen blade. Blocking a yoko cut, you deliver a powerful shomen cut which the samurai is unable to parry. You cleave him in two.
The daimyo, ad libbing admirably, thanks you for your loyal service and makes you a samurai, giving you 10 koku of rice annually. You live for the rest of your life on this generous pension, occasionally making war on the inferior Chinese and the white barbarians who are attempting to bring Christianity to the shores of Japan.
