Shu finds the gang and and now is in the Grand Kingdom's capital city. While that, Grand Kingdom's army is fighting Jiburaro Kingdom's army. Shu Nand the others get inside Nene's place(nene is a villain). While Shu and the others are finding Nene, they discover that Nene is planning to take out children's shadows and using them as their weapons.

Shu and Co. encounter Homeron again. He reveals that the information of the Extra 7 is somewhere in Gran Kingdom's Castle Des La Teste and they will have to infiltrate it to get to its master computer. Conrad L. Lawrence is shown to be imprisoned in a local prison run by Cynthia which Homeron also tells Shu. Zola comes up with a plan to lure the guards from Castle Des La Teste in order to rescue Conrad and get the information. As the others attack the prison, Homeron, Kluke, and Bouquet infiltrate the castle. Upon rescuing the captive soldiers, Shu and Jiro free Conrad and run into Cynthia. Lemaire also arrives to help Cynthia and both of them begin to overwhelm Shu and Jiro until a successful attack from Blue Dragon and Minotaur weakens them down. Zola catches up after destroying the robots that came with Lemaire. With the reinforcements from Castle Des La Teste approaching, Zola issues a retreat as Homeron begins his infiltration.

After Gilliam, Todd, Bishop, and Cynthia's defeat, General Logi sends Andropov, Lemaire, and Schneider to take on Shu and Co. Zola faces off against Lemaire while Jiro and Marumaro fight Andropov and Schneider. Lemaire has Deucalion use its bazooka attack to create a crater where Lemaire will have the advantage in. Shu faces off against General Logi. With Lemaire defeated by Zola, Kluke goes to help Shu while Bouquet infiltrates Logi's ship.

Shu and Kluke continue their fight with General Logi and Valkyrie. Marumaro is knocked unconscious by the attacks launched by Schneider's Isabel and Andropov's Alubujem. Luckily, Zola arrives to help Jiro. Meanwhile, Bouquet uses her invisibility to sneak onto Logi's ship and reclaim the Extra 7. Kluke falls unconscious after an attack that broke Valkyrie's shield (whose left wing ends up cut off in the process). The power surge of Blue Dragon's battle with Valkyrie results in a power surge that breaks the glass that's holding the pages. An invisible Bouquet seizes them, but runs into Delphinium who managed to detect her. Logi and Valkyrie managed to bring down Blue Dragon, but Shu gets enraged enough to bring Blue Dragon up to a powerful level. Andropov and Schneider managed to get Logi out of there at the last minute. A debris from the battle makes a hole in the ship as Bouquet manages to make her escape through it only for Delphinium to use her shadow to snatch back the Extra 7 at the last minute. However, Bouquet managed to memorize them enough for her to use Hippopotamus' shape-shifting to turn into copies of them for Shu and Co. to try and decipher.

Arriving in a local town, Shu recalls about his attempts to Jiro and Kluke to help him. This causes Marumaro to become concern and Bouquet to feel neglected. Marumaro ends up encountering dancing sisters Donna and Reina. When Marumaro brings them to Shu to cheer him up, the sisters end up dancing with Shu and Noi until Bouquet arrives getting into an argument with Shu. The sisters break from Noi and end up sucking the life out of Shu and Bouquet. Donna and Reina then perform while sucking the life out of some of the townspeople. Marumaro ends up deciding to correct this problem and obtaining Noi's help. Donna and Reina recall when they used to be down and out until Mikhail arrived and gave them Dragon Scales to make them more beautiful. This also caused them to absorb the energy of jealous people. When Donna and Reina leave, Marumaro and Noi emerge from their hiding spots as Noi tells Marumaro that Donna and Reina have the crests of the Dragon Scale on their necks. Marumaro and Noi end up disguising themselves as one person so that Marumaro can use his shadow power to deactivate the Dragon Scales starting with Reina. It doesn't go well when their disguise eventually fails. Marumaro ends up enticed by their beauty until Noi ends up not showing off his jealousy. Donna and Reina end up attempting to entice Noi with their beauty making Marumaro jealous. When Donna and Reina end up trying to absorb Marumaro's jealousy energy, Noi ends up biting Reina. Using Saber Tiger, Marumaro ends up driving the Dragon Scales out of Donna and Reina. Once the Dragon Scales were destroyed, those that they have drained energy from were restored. As Shu starts to regain his energy, he finds out that the name of the girl that has been appearing in his dreams is Primella. He ends up waking up alongside Bouquet. With Donna and Reina still unconscious with Noi stating that they won't remember a thing, Shu, Bouquet, Marumaro, and Noi take their leave. Shu finds out that Marumaro had been worried about him and Bouquet. Shu and Bouquet then end up in another argument revolving around what happened between him and Donna and Reina.

Returning from a recon, Jiro and Xie inform Shu, Bouquet, Marumaro, and Noi about the White Guardians advancement and where they have set up camp. With some persuasion from Shu and the others, Bouquet and Hippopotamus shapeshift their way onto the airship that Primella is on. When she does get to Primella, Bouquet tries to get her to help them in any way. Later that night, Shu and Jiro lead a raid upon the White Guardians camp. One of Dr. Tarkovsky's henchmen leads the ground attack with their new hand cannon weapons as the airship takes off. While the others handle the White Guardians, Shu and Blue Dragon go after the airship only to be held back by the hand cannon weapons. Shu makes onto the ship where Primella was waiting, but Vermillion knocks him off where Shu falls into the forest below.

At a Rosekstan base, General Logi oversees the upgrades to the giant exo-suits while on Sleipnir, Matilda is given the status on the giant wall. Rosekstan's forces still try to breach the wall as Shu, Bouquet, Marumaro, and Noi arrive at the nearest village. Matilda resolves to use a powerful laser that would guarantee the wall's destruction at the price of the nearest village. As Saber Tiger is riding the others toward the giant wall, they are ambushed by Matilda and the exo-suit warriors. Not wanting Matilda's plan to happen, Shu unleashes Blue Dragon as Matilda unleashes Zephyrus.
