The twin children of Grenmolt, Grassa & Tarrett, race through the fighting tournament 'Duel Masters' that their father once conquered. Duel Masters was a combat race held in the past, where participants fight their way toward the goal at the edge of the continent. Guest is a former friend of Grenmolt and someone who once fought on equal terms or better against the Dragon King of the dragon world. They usually hide their face with a hood.
A Dragner girl who claims to be the legitimate successor of 《Q.E.D.》, called 《Q.E.Deux》. Her true identity is a clone of 《Q.E.D.》 backed up by 《Dragon Wave Carrier Evidegoras》. Her appearance and clothing are almost identical to Q.E.D., but unlike her predecessor, she wears a dragon helmet. Though she's a bit taller than Grassa, she's slightly smaller than Q.E.D. and gives a younger impression. Her personality is also very different from the original. Q.E.D. conducted joint research with 《Dragon Overlord The=Deadman》, and after losing to Grassa, she became completely obsessed with Grassa.
The sister Grassa inherited her mother's exceptional figure but is as active as a boy. She trains hard to inherit the 'Explosive Sword Technique' from her father, a martial art that the Glen clan has passed down through generations as masters. In a way, she takes after her father. At one point, she managed to dragon-resolve the soul of Gaial, which shouldn't exist, and around the same time entered the race 'Duel Masters' that was restarted after 20 years by 《Genius Miroku of the Immortal Realm》. Grassa is fired up because this is the same race her father once participated in, but the two transcend dimensional barriers to gain even greater power and descend onto new battlefields.
An unexpected accident occurred when Purgatory Emperor King Romanov descended to steal the Draghearts. Even Miroku couldn't overlook King Romanov's misuse of his invention and stood up to him, but was criticized for his bad habit of creating disasters and then abandoning them. Hit by the Sword of Wisdom and Pursuit, he was defeated. Though he fell into a desperate crisis, he didn't give up and gave the revived Grassa and others new power - Xenotech Armor. However, the Xenotech Armor still lacked a power source story, so it only worked when Grassa and the others input their own ongoing story into it.
Having trained under 《Dragon Overlord Love Ace》, who values strength of heart and love over pure power, Tarrett has grown into a small, slender beautiful boy who could be mistaken for a girl, showing no trace of his well-built father's features. Tarrett is calm and goes at his own pace. He's a love maniac who connects everything to love.
The Snow Fairies who helped with his revival are also incorporated into him, and he leads his direct Seven Great Knight Orders, making his forces quite dangerous in scale. This battle is suggested to be connected to the fight between Jashin and COMPLEX unfolding in another world. After Grassa and the others won their battle against their aunt, he escaped with the Gysaga (Hero's Story).
