Shu and the others manage to protect the village from the enemy. The ‘Knight Master’ (Zola) convinces Shu to come along on their journey.

The gang begins the attack to attack the grand kingdom. Logi attacks with his dragon.

Shu and his friends want to hire an informant to help them find the Extra Seven but are told that an informant named Homeron the Great had died in battle against Gran Kingdom. At the same time, they meet the other Homerons ranging from Homeron the Original, Homeron II, Homeron the Legitimate, and Homeron Jr.. To pay for another informant, Shu heads off on his own to defeat the dangerous monster called the Gigarus and claim the reward. Shu and Blue Dragon managed to defeat the Gigarus and the group learns that the woman that hired Shu is actually Homeron the Great. However, Marumaro has gotten lost from the group.

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.

Conrad and a Knight Master named Griz join up with resistance headed up by Legolas and Daner in a nearby city and joins him in exploring the ruins of the Investiture Beings there. Shu, Bouquet, Marumaro, and Noi arrive at the city as Lotarus is encountered by Delphinium and Deathroy. Deathroy unleashes Chimera as White Brigade's weapons fire at Lotarus. She manages to evade the weapons and Delphinium's shadow before turning into her dragon form. While Lota deals with Delphinium and Deathroy, she also unleashes winged creatures that attacks the White Guardians. Lota takes the opportunity to escape while Delphinium and the White Guardians are occupied. Shu meets up with Legolas and Conrad and they descend into the underground caverns that are underneath the city. Noi then reads the messages found on the floors of the cavern. When Shu has Blue Dragon punch the artifact on the wall, he is sucked in.

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.
