The Sport is War

Slayer's War Ensemble:

"The sport is war total war
When victory's a massacre
The final swing is not a drill
It's how many people I can kill."

This was true during Nobunaga's career as well as other Sengoku warlords in 16th century Japan.  It was the age where bloodshed was king and the sword ruled the land.  From Okehazama to Nagashino, Nobunaga killed the enemy as much as can.  It did not matter if they were killed on the battlefield, assassinated, or starved to death.  During the Battle of Okehazama, taking heads were not necessary during the heat of the battle.  That was for later.  Nobunaga was quoted as saying, "Kill and keep moving!"  In this sense, kill as the enemy as much as you can.

Nobunaga no tame!
