With his village hanging in the balance, Shu awakens the legendary Blue Dragon, a Shadow of incredible power and strength.
The Blue Dragon has been awakened-but can Shu control it? He'll need the help of Zola, a shadow wielder who takes it upon herself to educate the boy about shadow powers to tell Shu about Shadow powers, as well as the Book of the Beginning, which tells the story of the battle between Light and Darkness. For Shu and his friend Kluke, there is no turning back, as they are recruited to join Zola and Jiro on a new adventure...

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...

Shu and Blue Dragon once again challenge General Logi, but Shu's power is still far below that of Logi's. Plagued by doubts about his inexperience, Shu can't draw out all of Blue Dragon's power. Logi continues to taunt Shu and Blue Dragon and battles all around grow in intensity.

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.
The heroes enter Bouquet's stolen ruins, where Nene is waiting for them. While the others are engaged in battle, Bouquet is transported deep within the ruins by the power of the ruins. Nene threatens that he will destroy the ruins before Bouquet can unlock her power. Even though it looks like Shu and the others are more powerful than before, Nene remains confident.
Shu and his friends are stronger than ever before as they join together to fight Nene, their biggest foe. At first it looks as if they have Nene cornered, but Nene proves that he is not easily defeated as he calls upon his Shadow research and increases the number of his Chimera to seven.
The team is astonished as they watch Nene draw his seven Chimera together to form one monstrous Shadow. Following Kluke's lead, Shu and the others launch an attack on the gargantuan Chimera, but their attacks end in vain and Shu is knocked unconscious.
After defeating Nene and freeing the children captured by Grankingdom, Shu and his friends return to the City of Logic. Conrad, Legalas and refugees from various kingdoms and nations celebrate their return. Although they have successfully completed their mission, Jiro harbors feelings of emptiness.
After seceding from Grankingdom, Logi established a new nation of Shadow Extremists that he called "Rosekstan". Many nations and kingdoms that were once under the rule of Grankingdom begins to fall under Logi's influence. Andropov follows Logi's orders to track Shu and the others.
As the team arrives at the Sealed Grounds, Jiro begins to question Zola's plan, but she won't divulge any information. Just as anxiety and fear spreads amongst Shu and his friends, Logi, Andropov, and Schneider make their appearance.
Shu and the others rejoice at the return of Kluke. But the celebration is short-lived as all seven descendants of the Soldiers of Light assemble at the Sealed Grounds and land begins to close in on the Shadow Wielders. Logi tries to avert Zola's plan by attempting to destroy one of the Shadow Wielders.
Shadows grow from the Darkness and Darkness engulfs lands and people into it. Shu and his friends are paralyzed with shock by Zola's disappearance into the sphere of Darkness. With no recourse or way to stop this terrible event, the team is forced to watch as the Darkness is released into the world.
Shu and his friends continue to provide assistance for those who have been affected by the rapture of the Darkness. The team grows more anxious and impatient as they fail to find an effective line of attack against the Darkness. Shu's trust in Zola is unswaying, angering Jiro into to picking a fight with Shu.
Shu forms a hypothesis that the descendants of the Seven Soldiers of Light might be able to seal the Darkness once again, so he goes to Logi's base to ask for his help. Logi had come up with the same theory and informs Shu that he's found a way inside the Darkness.
The descendants of the Seven Soldiers of Light unite as one again, but each has their own purpose. As soon as their battleship enters the Darkness, they are attacked by the Shadows of Darkness. The captain of the battleship attempts to fend off the Shadow attackers with cannons, but the numbers are too overwhelming and some breach the ship.
Logi, Schneider, and Andropov stay behind and distract the Gatekeepers of Darkness, allowing Shu and his friends to flee as they make their way to meet Zola again. Shu insists that he stays behind with them.
Shu and the others finally reunite with Zola at the Sealed Grounds. In an attempt to uncover the truth, they ask her if there was a specific reason why she released the seal on the Darkness, but Zola denies there were any such circumstances, simply saying that she returned the world to how is should be.
With his medallion destroyed, Shu is swallowed by the Darkness. Instantly, Zola sends Jiro and the others into the Darkness, as well, and, it seems, that all hope is lost. While in the Darkness, Blue Dragon realizes that the lower half of his body now exists and a voice from the dark abyss tells him that this is his true form.
With Zola infused with Killer Bat, she has become even more powerful. While Jiro and the others are fighting off the Shadows of Darkness, Shu runs head-on into Zola. Zola absorbs the infinite power of Darkness and changes form even more.
