Madan Senki Ryukendo

A young man sets foot in Akebono City, a town likely to be anywhere in Japan. A newly appointed police detective, Kenji Narukami. The town is under martial law. A horde of demons was pouring in and causing big panic in the city. Kenji, who stands alone, witness policemen running away at first sight of demons, also sees S.H.O.T.'s warrior, RyuGunOu, wiping out the demons thus regaining peace to Akebono City. However, a further threat to the town appears, the attack by Demon Beast Reptolilix! Kenji bravely challenged the battle...

The people of Akebono City are suffering from the evil organization known as Jamanga. They are collecting the negative energy generated when people feel fear and anxiety for the resurrection of the Great Demon King. On the other hand, Kenji is taken to the secret base of S.H.O.T., an organization that fights against Jamanga. Therefore, he vows to fight as S.H.O.T.'s warrior, RyuKenDo, together with the sword, GekiRyuKen, who has the will and can speak languages. At that time, the Plant Demon Beast Giga Flower attacks the town. It's time to use the new key, Fire Key for RyuKenDo!!

Jamanga General, Doctor Worm, arrives with a huge armoured black tank to attack Akebono City! The demons are catching the residents one after another. Kenji comes across a female police officer who shoots and fights with a handgun. It is Ichiko and Ritsuko of the Akebono Police Department, Traffic Division. Kenji is impressed by their determination to protect their city by themselves and transform into RyuKenDo and summon the beast king, Brave Leon. Brave Leon is transformed into Leon Trike. To defeat the armoured black tank, RyuKenDo began to track them using Leon Trike!

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!

Kenji, who gained Fire Mode, Aqua Mode, and even the Beast King, is completely ecstatic. Around that time, another General of Jamanga, Jack Moon, appeared in Akebono City, and after searching for S.H.O.T.'s information, people were trapped in a crystal ball! Komachi, a ghost that appears in Akebono City stopped Kenji from facing the fight alone. However, he struggles with the powerful attacks from the proud swordsmen, Jack Moon. An unexpected reinforcement appeared there ...

As a result of analyzing the acquired Madan Key at S.H.O.T., it became clear that it was a key to activate RyuGunOu's new powerful technique, the Dragon Cannon. So in order to acquire the powerful technique, Fudou repeatedly undergoes severe training. In the sky of the city, Jamanga's demon beast, Balloon Gunner, appeared. People who took a beam from Balloon Gunner, made them swells like a balloon and floated in the sky. Fudou, who completed the technique with amazing speed, decided to work with Kenji to defeat the enemy and save people...
