Shu and his comrades wander into a town that has been decimated. A pint-sized Shadow wielder named Marumaro attacks them, convinced that they are enemies. Will Marumaro be convinced of Shu's innocence in time to save the villagers from the real invading army, and taken on a pair of Shadow-wielding brothers at the same time?

Conrad, Griz, and Daner report what he has found underneath the city to Legolas. Upon remembering what Mikhail said, Noi tells Shu, Bouquet, and Marumaro that he is heading down into the ruins. Noi assumes his dragon form and flies down. While Bouquet and Marumaro have reached a disagreement, Conrad speaks to Shu about what to do with the Investiture Being ruins. Noi manages to get into the database when Lotarus in her dragon form arrives. A flying rock-like structure arrives floating above the city and is a threat if it lands on it. Shu unleashes Blue Dragon and checks it out. Panic occurs in the city as Griz and Daner speak with Bouquet and Marumaro. Blue Dragon attacks the rock structure as Bouquet, Marumaro, and Saber Tiger arrive to help. Bouquet and Hippopotamus merge with Blue Dragon and they attack the floating rock structure. Shu and Blue Dragon use whatever they can to destroy the rock structure and send its debris far. Lotarus takes her leave after this. Later that night, everyone is in the database room. As an eclipse occurs, secret data appears.

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.

Rosekstan begins their attack on Rudolph's war machine. Rudolph then unleashes his winged creatures, a bunch of Amethyst Dragons, a Moody Dragon, and a Phantom Dragon. Jiro, Kluke, Marumaro, Bouquet, Andropov, and General Logi unleash their shadows to attack the war machine while Noi looks for Shu. Meanwhile, Shu makes contact with Zola's spirit. As the battle progresses, Rudolph's war machine decimates most of the Rosekstan fleet. Just as one of the winged creatures is about to attack Jiro, he is saved by Delphinium and Deathroy (who have unleashed Chimera) as they arrive with reinforcements. Sleipnir fires its cannon at Rudolph's war machine but to no avail. Rudolph then fires the attack which decimates more Rosekstan airships as Noi charges towards the war machine.

Noi reveals himself to be one of the 'Investiture Beings', but keeps it from Shu and the others to keep their trust. The battle with Shu and Mikhail rages on again with Mikhail unleashing his Red Dragon shadow even when Marumaro and Saber Tiger throw themselves in front of Mikhail's attack. Mikhail reveals his true form as the Red Dragon itself. Meanwhile, Lotarus notices the soldiers in white approaching. The warriors Vermillion and Furioso watch the fight recapping about Primella's prediction of Albarose' destruction when Dr. Tarkovsky appears identifying the Red Dragon as Mikhail as their tri-barrel technological weapons get positioned. Mikhail ends up overpowering Blue Dragon in fusion form. Shu refuses to give up when Mikhail starts attacking Noi for breaking the rules of the Investiture Beings. Then Noi transforms into his black dragon form, revealing himself in front of Shu and initiates the forbidden fusion with Blue Dragon to gain a new dragonite form and evening the odds with Mikhail. During the fight, the soldiers in white step in firing a tri-barrel weapon called the Brunack causing Mikhail to flee. The soldiers corner Shu and co. as Vermillion introduces them as the "White Brigade" and stated that their mission were absolute destructions of all shadows.
