Ii (pronounced “deadly” without the “deadl-” part) was born in 1561 into an extremely volatile and violent Japan. After having his entire family slaughtered when he was only three, Ii was raised by monks. Fucking warrior monks. He became beyond proficient in swordsmanship, martial arts, military tactics, horseback riding and causing high-impact blood-splatter across the countryside. He also reportedly mastered his chi, which meant he could shoot hadoukens out of his eyes. Probably.
He utilized these skills to become the leader of an insanely terrifying and deadly group of elite samurai shock troops known as the “Red Devils.” These harbingers of death donned horrifying masks and heavy armor that was blood-red, and deeply intimidated their enemies as they were ultra-violent and often broke formation just to appease their blood appetite. And Ii was their leader. And they nicknamed him “The Killing Machine.” You decide exactly how large his balls were.
