Marumaro attacks Shu and the rest, thinking they are responsible for destroying the city. They set a trap and capture Marumaro. After being freed by Zola, Marumaro finds the citizens and Nene's minions. Shu and the rest join the fight and face a pair of twin shadow users. The twins withdraws from the fight and Marumaro joins the team.

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

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.

Shu and Blue Dragon are sent to the nearest town to find a blacksmith to make a replacement part for the Mechat and also to get supplies. On their way to the nearest village, Shu and Blue Dragon save a boy named Tonto from local bandits whose jewels were taken from Tonto. Upon arriving in the village, Shu meets Tonto's sister who happens to be a blacksmith. Shu has some trouble when Tonto steals tomatoes, potatoes, and apples from three local farmers and Shu had to pay for those. Shu and Tonto get into trouble with Tonto's sister when she finds out that Shu is a Shadow Wielder and Tonto had been stealing again. After dodging her hammer before she collapse in sorrow, Shu learns that Tonto's sister hates Shadow Wielders after recurring attack by Shadow Wielders from Gran Kingdom. When asked why Tonto wants to become a Shadow Wielder, Tonto's sister states that Gran Kingdom returned last year with Ivanov and Gustav demanded tribute. Shu and Tonto's sister get word from one of the farmers that the local bandits have captured Tonto. Shu and Tonto's sister managed to find their hideout as the bandits use a tank and robots they stole from Gran Kingdom to attack Shu and Blue Dragon. Due to Tonto's sister not liking Shadow Wielders, Shu is easily taken down by the bandits and Blue Dragon causes them to retreat. After recuperating, Shu finally gets that replacement part for the Mechat and defeats the bandits before rejoining with the others.

Gilliam is shown recuperating at Castle Des La Teste and recovers quickly in a plot to take revenge on Zola. Delphinium allows Gilliam to take the type-three models of the Black Shadow robots with him. Kluke and Bouquet argue where to go next when Zola tells them that they have to refuel the Mechat. Meanwhile, Nene is informed that the drilling beam on his flying fortress is almost up to power. The groups Mechat lands at a nearby Gran Kingdom strategic refueling base. While Shu and Jiro protect Kluke while she refuels the Mechat, Zola and Marumaro take on the soldiers positioned there. Zola encounters Homeron the Legitimate in the guise of a Gran Kingdom soldier. Gilliam receives word from Delphinium that the Gran Kingdom strategic refueling base was attacked and heads over to that area. Kluke is told by Zola to head to the Hippopotamus Ruins since Nene's flying fortress is heading there. Gilliam attacks and Zola engages him while the others fight his Black Shadows. Kluke solves Chapter Seven of the Extra Seven and uses the crystal on her necklace to power up Phoenix when the Black Shadows charge up their attack. Kluke uses this new ability to block the attack and send it back toward the Black Shadows. Zola uses Killer Bat's Hornet Assassin attack on Euphoria which annihilates Gilliam.

Two years after the world is freed from darkness, a young dragon escapes and crashes to earth. Shu and Bouquet have joined Legolas' Sarbin resistance against General Logi. Shu leads a supply raid on a Rosekstan airship, then rides with Bouquet to investigate the crater, and encounter a mysterious boy named Noi. All three find themselves prey to a Rosekstan fleet. But a red dragon appears and decimates the Rosekstan forces. While evading the red dragon, Noi uses his Tosen Kyuden ability on Shu. With Noi's help, the Blue Dragon returns. After a fierce battle, Shu and Blue Dragon cause the red dragon to retreat.

During their search for Jiro, Shu runs across news of a small war about to happen between a Rosekstan sub fleet led by Captain Varenko and a small band of resistance led by Captain Crester (one of the surviving members of Grand Kingdom). The party continues forward anyway hoping not to get found, leading to the combination of Saber Tiger and Hippopotamus with the 'stealth mode'. During but a few moments, Crester's band of resistance were eliminated. It was then suddenly Micheal appears before Crester and grant him the power to call his own Wyvern-like shadow allowing him to devastate General Logi's sub fleet. Having found out that the shadow that Crester wields is different from the normal Shadows and the Artificial Shadows used by Grand Kingdom, Shu's party steps in to defeat Crester. After defeating Saber Tiger and Hippopotamus, Crester faces off against Shu and Blue Dragon. After Crester is defeated, Shu, Bouquet, and Marumaro learn about the 'Dragon scales' Mikhail handed out which can grant miraculous powers to the user. They then overhear one of the Rosekstan soldiers tell Captain Varenko that they lost contact with General Logi.

As the White Brigade prepares to attack Shu and the others, Shu fends off the White Guardians while Noi evacuates Bouquet and Marumaro away from the area. The White Guardians also retreats as Lotarus watches from afar. Mikhail is shown near a river badly wounded. Shu and Noi have a conversation regarding the events that occurred two years ago as the White Guardians continues their advancement. Later that evening, the village that Shu and Co. are resting turns out to be near the White Guardians' headquarters in the city of Nirvana. Bouquet uses her invisibility to listen out what the White Guardians is up to. Bouquet then unleashes Hippopotamus and takes the form of a White Guardian to throw them off track. Shu and Co. are spotted by some White Guardians, but are knocked out by Saber Tiger. Making their leave from the city, Shu finally encounters Primella in person.

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.

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.

Recovering from the fall, Shu is informed by Jiro and Xie about the advancement in the war between the White Guardians and the forces of Rosekstan. Shu then realizes that the village Kluke is living in is right in the middle of the invading forces. Meanwhile, Kluke and Andropov notice one of the Resistance's airships arriving in the village. When they start attacking, Andropov unleashes Alubujem who uses a flash attack to enable his and Kluke's escape. Kluke and Andropov are then pursued by the airship which destroys their house. Riding on a recovered Saber Tiger, Shu, Bouquet, Marumaro and Noi arrive at the ruins of Kluke's house. They then encounter two of the children that Kluke has been educating who tell them everything that has happened. Kluke and Andropov are still on the run from the airship until they crash her hovercycle into a tree. The airship unleashes their armored warriors who bring out their artificial shadows to attack. Andropov unleashes Alubujem to defend himself and Kluke. With some of them defeated, things weren't looking good for Andropov when he gets exhausted. He still tries to defend Kluke even though he has reached his limit. When Andropov is knocked down, Kluke throws herself in front of him as Phoenix is unleashed. As the armored warriors charge toward Kluke and Phoenix, Shu and Blue Dragon arrive in the nick of time taking out some of the the resistance's shadow armours, forcing them to retreat. Upon learning of the current crisis, Kluke and Andropov join up with Shu.

Kluke uses Phoenix's ability to teleport the group to General Logi's hideout. When Shu shouts for a meeting with General Logi, he manages to allow it since he noticed Andropov with them. While Shu and Co. are talking with General Logi, Delphinium and Deathroy infiltrate General Logi's hideout looking for info that will help the White Guardians. As Shu and General Logi continue their conversation, one of Logi's men enters informing them that the White Guardians is attacking the Rosekstan forces. General Logi and Matilda leave as Andropov goes after them. As Delphinium and Deathroy find a room with giant exo-suits, General Logi talks with Andropov where the General still supports Andropov when he feels bad about what happened to Schneider. Shu and Blue Dragon leave to help the forces of Rosekstan fight the forces of the White Guardians. Blue Dragon destroys their Brunacks upon arrival. Outside of General Logi's hideout, Noi notices the White Guardians forces approaching in large numbers.

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.

In a stormy volcanic area, Noi runs into Legolas nearby Z'Mey: a dragon sanctuary. Conrad also arrives with Griz and Daner. Meanwhile, Marumaro and Bouquet continue their search for Kluke. At a nearby town, Kluke is shown tending to the injured. Daner shows Noi an artifact that Conrad's group had found. Noi then leads Legolas, Conrad, Griz and Daner into Z'Mey and go through many obstacles to get to the main chamber. Meanwhile, Shu sees a nearby town that is annihilated when Rudolph arrives. Shu and Rudolph unleash their shadows and fight. Noi places the artifact in the area and it unveiling a shuttle called Mast Driver and its pyramid-like platform. The light it emits is noticed by Shu and Rudolph as Rudolph leaves. Meanwhile, Bouquet and Marumaro have met up with Kluke at the area where Primella's vision of her took place.

The battle between Rudolph and the Shu/Blue Dragon begins. Rudolph's shadow is matching blows with the Shu/Blue Dragon and nearly defeated Marumaro and the Bouquet/Saber Tiger. Rudolph starts to overwhelm the Shu/Blue Dragon. When Rudolph overwhelms the Shu/Blue Dragon sending him into a ditch with Primella and Dr. Tarkovsky falling after him. The attack also defeats Marumaro and the Bouquet/Hippopotamus. Noi even tries to have some words with Rudolph. Primella continues to glow and makes contact with Shu mentioning how she was a part of Zola before being separated from her by Killer Bat. After the talk, the Shu/Blue Dragon rises to continue his fight with Rudolph. Noi assumes his dragon form and tries to fight Rudolph, but to no avail. Before Rudolph can finish Noi off, the Shu/Blue Dragon saves him. Bouquet re-merges with Saber Tiger to assist Shu in the fight with Rudolph.

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.

Things aren't looking good for Rosekstan and Shu's allies. Just then, the Shu/Blue Dragon emerges with Primella in its hand. Primella wakes up as she is given to Dr. Tarkovsky and General Szabo. Rudolph emerges from the war machine and fights the Shu/Blue Dragon. They match blow to blow until Rudolph uses his intangibility to keep the Shu/Blue Dragon from hitting him and then multiplies to attack the Shu/Blue Dragon. With help from Primella, the Shu/Blue Dragon destroys the duplicates. The Shu/Blue Dragon collides its punch with Rudolph's punch. The hopes of Shu's allies, Marumaro's siblings, and even the thought-dead Conrad, Griz, and Daner help give the Shu/Blue Dragon the strength to fight Rudolph. Their combined attacks results in an explosion that destroys the winged creatures and the dragons that Rudolph had summoned. As the Shu/Blue Dragon falls to the ground, Rudolph starts to crack up and explode taking his war machine with him.

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.
