Some time after the battle in Line City.
Doga Ryuga and Rian, who continue to fight as protectors, encounter a new horror in one of the cities.
Meanwhile, the Demon Warrior Gen (Shimojo Atom) has gone to the shrine where the legendary Demon Castle, Radan, is sealed.
With a determined look on his face, Gen draws his Dharma Sword.
Gazing at him are the mysterious young man, Jinga, and the mysterious beautiful woman, Amiri.
