Giant iron weights crush buildings and cars. Akebono Police Station is in a state of trouble with the work of Jamanga. RyuKenDo struggles with the attack of the demon beast, Meganōma which can make iron weights fall from the sky. Not even a Blazing Slash can defeat it. So RyuKenDo summons a new beast king! The name is Gorilla Beast King, Fire Kong. However, Fire Kong, who has a lot of pride on the other hand, was hurt by RyuKenDo's words and ran away without listening to orders!!
O monstro MegaNouma causa grande destruição em Akebono, atacando juntamente com os Servos. Ryukendo precisa detê-lo usando seu espírito YuuOu, o gorila Fire Kong, mas as coisas parecem não dar certo quando o animal mecânico não lhe obedece.
