Fire RyuKenDo defeated the advanced demon, Tsukaima using his finishing move, Blazing Slash. At S.H.O.T.'s Base, the Madan key obtained from defeating Jamanga's armoured black tank was found to be Aqua Key by The Book of Canon of Light and began to adjust. But they don't know how to use it. On the other hand, Rin pointed out from the people in the city that the stronger RyuKenDo is, the more powerful the enemy will be. Then, the Tsukaima who should have been defeated appeared again. The enemy has challenged the battle with its new flame slashing power!
