Himika finally found out the hiding place of the dotaku. Hiroshi proposed not to wait for the opponent's attack, but to attack the great kingdom instead. However, Dr. Shiba dismissed it because of the opponent's strength. Hiroshi that can't give up goes out with the Big Shooter without listening to orders and goes to Kyushu, the place where the dotaku was found.
