Zola and the team assault the fortress to free the captives from the city. Logi defeats Zola, then defeats both Jiro and Marumaro. He leaves for an audience with Nene, leaving the twins in charge. Shu manages to manifest and control the Blue Dragon, defeating the twins in the process. Shu and the rest then receive a mission to escort Legolas to the capital.

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.

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.

When Nene's fortress starts attacking Coreed, Conrad has Shu and Co. ride giant birds called Gryphs to Nene's fortress while Conrad and the others fight Black Shadow Type-Two robots. Zola also tells Shu and the others that Nene is one of the descendants of the Soldiers of Light. They successfully infiltrate the fortress. Once inside, they end up in the S-Field and fight Black Shadow Type-Three robots which have nanobot technology that enables them to regenerate. After recurring take downs on the Black Shadows, Bouquet and Hippopotamus manage to find the control room General Szabo is in and gets in as Nene. Bouquet then reveals herself and then transforms into a Black Shadow Type-Three and manages to use Hippopotamus' new ability to copy the optic attack of the Black Shadow Type-Three which sends General Szabo flying into the air and exploding. After Bouquet shuts down the Black Shadows, Shu and the others locate Nene's throne room for the final battle.

After Shu's brief talk with Primella, Noi finds a path out of Nirvana while Shu options another route for their next destination. Shu and Co. make their way through the city while evading the White Brigade's patrolling shifts commandeered by Furioso's intelligent tactics. During this part, Bouquet's hair touching Marumaro's nose causes him to sneeze giving them away to one of the security shifts. Shu and Marumaro manage to take them down as the next shift appears. Lucky for them before the soldiers ca signal, Jiro arrived and took them down. Jiro manages to create a diversion as Shu and the others make their escape, but Furioso easily recognises the ruse. When Furioso gets ready to intercept and fire where Shu and Co. are, Dr. Tarkovsky intervenes and tells him and the soldiers in the area to fall back, courtesy of Primella's plea.

Kluke starts to get exhausted from various teleporting when getting some White Guardian soldiers away from the battle. After decimating half of the White Guardians' troops, General Logi clashes with Furioso. As the battle rages on, the Investiture Beings continue their meeting as Mikhail plans to take action upon both sides despite the objections of Hildegard and Lotarus. Shu and the Noi/Blue Dragon have begun their fight with Vermillion. Kluke finally collapses from the strain. Meanwhile, Delphinium and Matilda engage each other in battle which ends with Matilda having Zephyrus teleport her away from Delphinium and Deathroy. As Shu and Vermillion are locked in combat, Mikhail ends up leaving the floating city. General Logi and Furioso are still locked in combat until Furioso leads him into a trap consisting of the White Guardian soldiers firing their cannons at him. General Logi manages to evade it and makes a striking blow toward Furioso only for one of the White Guardian soldiers to throw himself in front of Furioso. Jiro and Xie continue their reconnaissance. General Logi's hideout blows up to reveal a weapon air fortress called Sleipnir which decimates some of the Brunacks. During Shu's fight with Vermillion, Mikhail arrives and assumes his Red Dragon form and starts attacking the Rosekstan soldiers and the White Guardian soldiers. Shu and the Noi/Blue Dragon managed to put up a barrier to protect Jiro and Xie. Shu ends up going into overdrive which starts to make the grounds unstable, but lets himself get beat due to the pleas of Kluke, Bouquet, and Marumaro.

The Investiture Beings have a meeting where they discuss what happened during the times of the Seven Soldiers of Light, the fight against Nene, when Zola went rogue, Mikhail's encounters with Shu, and Noi deserting the Investiture Beings. Outside of Lotarus' encounters with Bouquet, they discuss the battle between Rosekstan and the White Guardians and what Rudolph had to do to stop it. Fagino and Hildegard then bring up their encounters with Shu's group. After a talk revolving around Jiro, Kluke, the White Brigade's goals, and Rudolph's encounter with Shu, the scale-like mechanism they are floating over floats towards Rudolph. After that, Rudolph unleashes his winged creatures as the Investiture Beings lead them throughout the world as they are noticed by the White Guardians, Jiro and Xie, Kluke and Andropov, Legolas and Conrad's group, and even Shu's group as Rudolph's voice is heard.

Shu continues his fight with Rudolph. After taking a blow from Blue Dragon, Rudolph assumes his dragon form. Rudolph and the Shu/Blue Dragon are easily matched until Rudolph manages to strangle him. He repels Noi and the Bouquet/Saber Tiger. When Rudolph starts to finish off the Shu/Blue Dragon, Noi unleashes his power which enables his dragon form to get bigger. With this occurrence, Noi engages Rudolph. Both of them are easily matched. Right when Rudolph was about to finish off Noi, he is hit by an attack launched by the Shu/Blue Dragon. Rudolph enters a portal that he created and the Shu/Blue Dragon follows him into it. The Shu/Blue Dragon follows Rudolph into an area where he uses a war machine to defeat the Shu/Blue Dragon. The Investiture Beings' castle is starting to change shape into a large dragon-like war machine. Kluke uses her forcefield ability to protect them from its attack. Just then, Rosekstan's forces arrive as Shu's unconscious body is approached by Primella.
