A boy named Shu is obsessed with knight masters learns that one has appeared in his village. Shu gets excited at this possibility and goes in search of him. His village gets attacked after finding the "knight master". Shu unleashes his true power after finding his friends are in trouble.

Zola and company meets the king who grants her access to the ancient library. Shu finally meets a true knight master. Bouquet arrives at the city to find it under attack from Nene's robotic shadow users. Shu and company joins the fight. An ancient scroll is stolen in the chaos and given to a mysterious character.

Shu and the others have finally found Nene. Shu, Jiro, and Marumaro fight Nene while Jiburaru's army is having a hard time fighting Grand Kingdom's army. But then, Shu, Jiro, and Marumaro got to a big disaster and Zola needed to get in.

Homeron informs Shu and Co. about Delphinium who is a Secret Intelligence Agent from Gran Kingdom responsible for the theft of the Extra 7. The group then sees the warships of Sabalu Country (which used to be part of Gran Kingdom) passing. Zola concludes that they give the Sabalu Country airships a warm welcome when the Warship Norg is amongst the Gran Kingdom ships. They managed to obtain one of its Mechats for that action. As the battle starts, they find the Norg and Shu uses Blue Dragon to get Homeron on board. When Kluke lands the ship on the Norg, a fight between the robotic soldiers ensues. Homeron manages to gain some information and prevent the Norg from crashing. He then tries to get info from the ship's captain on where it took Delphinium. When he does squeal that General Logi has the Extra 7, the Norg starts to descend to the ground.

Arriving at the Blue Dragon's ruins, Shu and Blue Dragon have a confrontation with a shadow called Dark Dragon. After nearly falling for Dark Dragon's deceit, Shu and Blue Dragon engage it in battle matching attack with attack. Shu manages to overcome Dark Dragon.

Zola has been defeated while Marumaro and Saber Tiger free Kluke, Phoenix, Bouquet, and Hippopotamus. Shu and Jiro have Blue Dragon and Minotaur attack Nene. Nene combines the Chimera clones to form one large Chimera. Meanwhile, General Logi has dispatched his troops which will attack when Schneider and Andropov receive the command from General Logi. Nene uses Chimera's Dark Symphony attack which weakens his opponents. When Shu and Blue Dragon's attacks are countered by Chimera's attack, Shu falls unconscious. In a dream sequence, he encounters Lt. Dragnov and Homeron. Marumaro and Kluke are defeated as Jiro has Minotaur aim for the device on Chimera's forehead. Shu rises from his boulder grave for another bout with Nene. Assisting Jiro and Minotaur in attacking the crystal on Chimera's forehead, Shu and Blue Dragon learn that the crystal enabled Chimera to alter his elements. The limiter is unleashed as Nene and Deathroy merge with Chimera to form an amalgam of all three of them. With Jiro defeated, Shu uses every ounce of his power and manages to destroy Nene as Deathroy is shown lying on the ground. With news of Nene's defeat, General Logi gives the command and has Schneider take over Castle Des La Teste while Andropov attacks some Gran Kingdom airships. This is General Logi's act of his secession from Gran Kingdom which he announces.
