Cosishoo has a secret plan to destroy all the battleships of Kingdom go-Jo. Sishin, Thunder Jet's No.1 strategist, thinks to win this battle is to sink Racko's ship, "Imperial tiger." The ship appears in front of T.J.'s fleet as if it invite T.J.'s attack. Sishin is stunned when he find not one, but three "Imperial Tigers." T.J.'s fleet is losing battleships one after another under the hellish firing of three gigantic warships. Sishin uses all the remaining battleships as 'bates' and succeeds to smash two "Imperial Tigers." But, T.J. loses most of force in this battle.
