For the championship of Japan Pro-Wrestling, Toyonori was scheduled to face the 300kg Great, also known as the Killer Aircraft Carrier. Looking for a strategy to win the match, Toyonori visited the old man Sakurai, who was known as The Devil Captain during the Pacific War, and tried to learn how to fight like a submarine against the mighty aircraft carrier. After a week of hard training at sea, Toyotomi mastered the secret techniques and successfully defeated the Great.
