Strong arm flying in the sky Daian

Synopsis

Baron Ashura kidnaps Shiro, demanding that Mazinger Z be abandoned if Koji wants to save his life. Koji and his allies, who have set up their own investigation network, pinpoint the location of the Submarine Fortress Saluud, but they can't make a move as long as Shiro is held hostage. Before Sayaka, the Mechanical Beast Dian N4 appears, attacking her with its flying arms. Koji receives the alert and tries to fight by boarding the Hover Pilder, but Baron Ashura separates him from Mazinger Z.
