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...

Zola's group arrives at the Republic of Metia, the nation next to the Grankingdom. From there they hope to cross through a canyon into the Grankingdom, but General Logi is ready and waiting with an ambush. With the formidable Shadow wielders Gilliam, Cynthia and Lemaire against them, Shu and his friends find themselves in dangerous combat.

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 manage 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.

After Gilliam, Todd, Bishop, and Cynthia's defeat, General Logi sends Andropov, Lemaire, and Schneider to take on Shu and Co. Zola faces off against Lemaire while Jiro and Marumaro fight Andropov and Schneider. Lemaire has Deucalion use its bazooka attack to create a crater where Lemaire will have the advantage. Shu faces off against General Logi. With Lemaire defeated by Zola, Kluke goes to help Shu while Bouquet infiltrates Logi's ship.

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 breaks Valkyrie's shield. The Blue Dragon's battle with Valkyrie breaks the glass that's holding the pages. An invisible Bouquet seizes them but runs into Delphinium. Logi and Valkyrie manage to bring down Blue Dragon, but Shu gets enraged enough to bring Blue Dragon up to a powerful level. Andropov and Schneider manage to get Logi out of there at the last minute. 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.

Shu and Co. work on deciphering the Extra Seven pages that Bouquet shapeshifts into. Meanwhile, at Szabo's request, Nene orders General Logi to take a break from his mission. With the Extra Seven deciphered, Shu and Co. steal one of the Mechats from a Gran Kingdom airship and head to the ruins at Talta Village.

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.

Nene sends General Szabo to the capital of Galga to attack Shu and Co. Jiro is attacked by General Szabo. This time, General Szabo unleashes his Mighty Quartet to assist him. Minotaur manages to pull off a retreat to get Jiro out of there. After a brief talk with Kluke, Jiro is attacked by General Szabo and his Mighty Quartet. Shu and Kluke arrive as General Szabo merges with his Mighty Quartet to form Ultimate Szabo. As Shu unleashes Blue Dragon, General Szabo unleashes a giant robot to fight Blue Dragon. Zola, Marumaro, and Bouquet arrive just as Blue Dragon breaks the giant robot's left hand. Jiro and Minotaur knock Ultimate Szabo into the lake. After some attacks from Ultimate Szabo, Jiro and Minotaur create their own whirlpool and eventually destroy Ultimate Szabo as Shu and Blue Dragon destroy the giant robot. Delphinium tells General Logi that Blue Dragon and Minotaur have gotten stronger and part of the Extra Seven has been deciphered by Shu and Co.

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.

General Logi is informed on the development of the Extra Seven. Shu and Co. head to Marumaro's village. When Marumaro wants to fulfill the prophecy of the original Saber Tiger wielder, he has Saber Tiger remove the guardian statues from the top of the other Devees' houses causing the other Devees to get angry and chase them. Marumaro then goes on a beautiful girl-viewing activity causing one of them to issue a complaint to Marumaro's parents. Zola sends Shu, Jiro, Kluke, and Bouquet to stop Marumaro. After catching up, Zola tells them to lure Marumaro into the canyon. Marumaro and Saber Tiger managed to get through every trap and barrier to gain a new power. Meanwhile, General Logi heads off on his own and leaves Andropov and Schneider in charge of the ship.

Gilliam is 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. While Shu and Jiro protect Kluke while she refuels the Mechat, Zola and Marumaro take on the soldiers positioned there. Gilliam receives word from Delphinium that the Gran Kingdom strategic refueling base was attacked. 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 and Bouquet argue over which ruins to go to first, and Kluke derides Bouquet for being useless. Needing to refuel, the group enters enemy territory where they learn from an informant disguised as a soldier, Nene is on his way to the ruins of Bouquet's power.
