With my bodyguard on a hill, On top of the flag in a citadel in my last city region getting attacked from all sides by Yari Samurai's.. Exhausted, dying as the last man on my side which used to be a 2000 man army taking attack, after attack. Ending the war by uniting Japan against myself after having my large 40region empire fall when my eighteen vassals all backstabbed me as the Shogun declared me an enemy of the state.
Death by last-stand at the age of 74.
I can think of worse ways to go.
*Looking at the man below me*
Very unlikely to happend mind you. . Unless some kind of world-war starts and im somehow dragged into the military and get a high rank. And the thing drags on and my side looses.
