A boy named Shu is obsessed with knight masters learns that one has appeared in his village. Shu gets excited at this possibility and goes in search of him. His village gets attacked after finding the "knight master". Shu unleashes his true power after finding his friends are in trouble.

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

Training under Zola, Shu is eager to prove that he's worthy of being a Shadow wielder, but summoning and controlling the Blue Dragon at will isn't going to be easy. If that wasn't enough, Shu's rivalry with Zola's companion, and fellow Shadow Wielder, Jiro is growing. But the rivalry is put on hold when a Grankingdom assassin sets his sights on Jiro!

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?

Will Marumaro be convinced of Shu's innocence in time to save the villagers from the real invading army, and take on a pair of Shadow-wielding brothers at the same time?

Shu and the others take the fight to the enemy when they invade a Grankingdom base where some villagers are being held. But General Logi, the base commander, has a past history with Zola and some shadow powers of his own, and he soon has Zola at his mercy. If there was ever a time that Shu needed to master the Blue Dragon, it's now...

Our heroes are determined to visit Jibral Castle, where they seek the king's help. On the way they stop in a village, where they rescue a waitress named Bouquet, only to find themselves in the middle of a disastrous misunderstanding. Confronted by a monster, they utilize their Shadow powers to fight the beast, but is the monster truly a monster, or is it actually Bouquet's Shadow?

Shu and his friends arrive at Jibral Castle, where rumors about ghosts are spreading like wildfire. When a member of Zola's party becomes a prime suspect, the group takes it upon itself to solve the mystery, leading to a confrontation with Salinas, an enemy Shadow wielder.

At their meeting with the king of Jibral, Zola requests permission to view the all-important "Book of the Beginning." Shu is eager to meet Conrad, the king's right-hand man, and a reputed Knight Master. But the group's excitement is put on hold when a Dragnov unit from the Grankingdom attacks with a fearsome new weapon: the "Black Shadow Type One."

During the battle with the Grankingdom, seven pages from the "Book of the Beginning" were stolen--pages with key information about Shadow powers. Zola's group decides to make for the Grankingdom, and head out to sea--with Bouquet on board as an unexpected stowaway. When a suspicious fog rolls in, and Shu and his friends are overcome with mysterious symptoms, it's up to Bouquet to save the day...

After being split up, the group starts to slowly reform, while Shu has a run-in with a mysterious man (who unbeknownst to Shu is Gran Kingdom's Lt. Dragnov) who leaves on a motorcycle after getting a call through a communication system. When Shu meets with the others, a war breaks out between the Black Shadow robots (now with their shadows upgraded into Type-2) led by Lt. Dragnov. The two release their Shadows and fight each other. As Lt. Dragnov's Berserker and Shu's Blue Dragon are locked in combat, Schneider brings out Isabel to snipe Lt. Dragnov.

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 the others have finally found Nene. Shu, Jiro, and Marumaro fight Nene while Jiburaru's army is having a hard time fighting Grand Kingdom's army. But then, Shu, Jiro, and Marumaro got to a big disaster and Zola needed to get in.

Shu worries of Kluke being unconscious, while Jiro worries about defeating Nene. Shu and the others discovered that they still have a hold on the criteria on the suspect who killed the saineles. They say that the suspect is a age of 20 to 30,she has blue hair, and has perfume on her body. So, Shu and the others decide to get the extra seven pages to get stronger and defeat Nene.

Kluke has woken up and is good now. Shu and the others continue their journey to the book of origins. Now Shu and the others are in logic city in their journey.

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.

Marumaro finds himself in hot water when he flirts with the innkeeper's wife, and he's in even deeper trouble when it turns out the innkeeper is a Shadow Wielder who deserted Gran Kingdom's army with the "wife" being his shadow. They soon learn that Marumaro isn't from Gran Kingdom. Marumaro and Saber Tiger later defend them from a Gran Kingdom captain and his troops with the innkeeper on his bounty list. Marumaro and Saber Tiger defeat them and they reunite with Shu and the others.

Shu's informant Homeron is gathering information about the Extra Seven. Shu and Co. arrive at Flame Phoenix ruins. When Kluke disappears, she ends up in the area where she first encountered her Phoenix shadow and asks it how she can call upon its power again. Phoenix tells Kluke that the answers lie in herself. Kluke then receives a necklace and rejoins Shu and Co. When they find Jibral's scattered army being attacked, Shu and Co. join the battle. Upon defeating the robotic soldiers and their shadows, Shu and Co. are soon attacked by a giant robot. Kluke brings out her Phoenix Shadow to use its barrier to protect everyone enough for Shu to use Blue Dragon to destroy the giant robot. Meanwhile, Homeron receives news the mysterious woman who stole the Extra 7 is heading west.

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.

Conrad takes his soldiers to head to the west side to gather others that will fight Gran Kingdom. Homeron continues his infiltration to look for Castle Des La Teste's master computer. Gilliam and his followers Todd and Bishop attack the recently released prisoners resulting in Marumaro and Saber Tiger fighting Gilliam and Euphoria with Shu's Blue Dragon and Kluke's Phoenix joining the battle. Jiro and Zola fight Todd and Bishop. With the help of Phoenix, Marumaro and Saber Tiger managed to damage Euphoria. Andropov informs Gilliam to have his group retreat. As for Homeron, he learns the name of the white-haired woman to be Delphinium.

Cynthia has grown jealous of Bouquet's beauty. This causes her to seek out and eliminate her. A fight on the narrow path causes everyone to fall into Death Valley. Bouquet brings out her Hippopotamus shadow to turn into a ball...which ends up scattering everyone. As Shu and Co. evade the experimented creatures there, Cynthia learns from Andropov that the fog there has softened the cliff sides to the point where it is impossible to climb. As Andropov tries to find a way out for Cynthia, Bouquet and Hippopotamus secretly follow her to find a way out with Bouquet leaving a trail of her clothes for the others to follow. When her cover ends up blown near the exit of Death Valley, Cynthia attacks. Things weren't looking good for Bouquet and Hippopotamus. When Shu and Co. arrive, Cynthia retreats.

Homeron informs Shu and Co. about Delphinium who is a Secret Intelligence Agent from Gran Kingdom responsible for the theft of the Extra 7. The group then sees the warships of Sabalu Country (which used to be part of Gran Kingdom) passing. Zola concludes that they give the Sabalu Country airships a warm welcome when the Warship Norg is amongst the Gran Kingdom ships. They managed to obtain one of its Mechats for that action. As the battle starts, they find the Norg and Shu uses Blue Dragon to get Homeron on board. When Kluke lands the ship on the Norg, a fight between the robotic soldiers ensues. Homeron manages to gain some information and prevent the Norg from crashing. He then tries to get info from the ship's captain on where it took Delphinium. When he does squeal that General Logi has the Extra 7, the Norg starts to descend to the ground.

Following the trail of the downed Norg ship, Shu and Co. look for Homeron and the Norg's crew in the Great Brandish Forest which is on the border of Gran Kingdom and Sabalu Country. Delphinium is also in the woods searching for the Norg Crew. Shu, Jiro, and Marumaro as well as Homeron and the Norg Crew are soon attacked by Obacks (one-eyed single-horned bears). Even when Shu catches up with Honmalon at where the Obacks nest, Delphinium arrives and uses her shadow to kill Homeron. After evading Blue Dragon, Delphinium escapes. With the crew of the Norg freed, the captain of the Norg tells Shu that the Extra Seven are on General Logi's ship.

Nene's flying fortress invades Raqueeva. When General Szabo questions Nene about General Logi's activity, Nene tells him to let General Logi handle Shu's group. On the trail of Logi's ship, Shu and Co. end up in battle with the Independent Flying Squadron again. This time, they've all been equipped with Power Boosters to make them more powerful and are instructed to fight them even if it is to the finish. Zola and Marumaro fight Gilliam, Todd, and Bishop while Cynthia and Schneider attack Shu and Co.

The battle against Logi's Independent Flying Squadron rages on as Shu, Kluke, Jiro, and Bouquet struggle to take down Cynthia while Zola and Marumaro do the same for Gilliam and his minions. When Marumaro takes down Bishop, he and Zola focus on the remaining two when Gilliam and Todd's Power Boosters overload. When this is discovered, General Logi orders Cynthia, Gilliam, and Todd to retreat, but Gilliam and Todd are shot down by Zola after Marumaro decoyed them. Despite Cynthia going into overdrive, she is defeated by Jiro anyway.
