Accompanied by Rose and the Sparrowfeathers, Sorey and friends head for a new land, Rolance. On the way, some rogues try to sell Rose stolen herbs. When she sees through them, they threaten her, but Rose thrashes them easily. Sorey is impressed with her sharp business acumen. At night, he continues to train with Lailah, learning to recognize and stop the Malevolence; honing his skills to confront the powerful mass of Malevolence known as "The Lord of Calamity." The party arrives in the commercial city of Lastonbell and meet Mayvin the storyteller.

In Lastonbell, the assassination guild known as the “Scattered Bones” led by Rose kills the bishop who has been fattening his pockets and silencing any who might talk. Despite feeling uncomfortable about Rose’s attitude, Sorey joins her for breakfast. Sergei, the general of the Rolance imperial guards, the Platinum Knights, appears. The previous night, he had come looking for Sorey, only to end up getting intoxicated, and has come to apologize for his unbecoming behavior. Just then, an explosion occurs near the city’s sanctuary, causing the ground to collapse. Sorey and company rush to check. After confirming that the Malevolence caused the collapse, they enter the sanctuary to perform a purification.

Rose is enraged upon learning that her trading partner Guren was captured by the Bishop’s men and is no longer alive. To ease her anger, Dezel the Seraph sets out to destroy the church sanctuary in Lastonbell. While Lailah and the others go to stop him, Sorey goes to join Rose. Although she cannot see Dezel, she becomes aware that Dezel is causing the phenomenon occurring near the sanctuary, and urges him to stop. Sorey asks Dezel, “Why did you try to destroy the sanctuary?” And Dezel recounts his past, and how he first met Rose.

Long ago, her comrades in the Windriders and her foster parent Brad had been driven to death by the imperial prince, Konan. Rose receives news of Prince Konan’s whereabouts and begins preparing for a journey of revenge. Sorey is told of the unceasing rain by Sergei and decides to go to Pendrago, the capital of Rolance, to investigate the cause. Worried about Dezel, Sorey asks Rose to join him on the journey, but is flatly turned down. As he heads out to Pendrago, he asks Mikleo to follow Rose, and Dezel who is with her. Mikleo agrees, and he and Edna set out to check on how Rose’s journey is going.

Rose finally finds Prince Konan, the target of her revenge, but he has already turned into a hellion. Her attacks against him are useless and he counters with a power that is beyond human. When Dezel comes to her assistance, the tower inside which they are fighting suddenly collapses. Sorey rescues them, but Rose is distraught that Konan is nowhere to be seen and that she did not “finish him completely.” Sorey tells Rose he disapproves of her being an assassin, to which she replies, “There are guys in this world who must be killed.” And Sorey goes on to explain about “Malevolence.”

Escorted by the Platinum Knights, Sorey and friends arrive at the residence of Doran, ruler of the Rolance Empire. Doran recounts to Sorey the legend passed down through the imperial family, about the Malevolence in the world and the “beginning of calamities.” Furthermore, he gives Sorey the disturbing news that Alisha of Hyland seems to have been put house arrest. Sorey is shocked, but decides that the Malevolence must be stopped as soon as possible and heads for Pendrago. Meanwhile, Rose who has learned from Sorey that the Malevolence is the cause of the disasters in the world, asks Dezel of a way to see this Malevolence. Then she goes to Sorey with a certain proposal for negotiation.

With Rose who enters into a Squire’s contract with him, Sorey goes to Pendrago and purifies the dead dragon which has continued to fester Malevolence. Then, Alisha’s voice reaches him from Ladylake, calling for his help to deal with the tornadoes that have appeared. She loses connection with him but Alisha heads for Sitole which is in the path of the tornado, intent on rescuing the people. Alisha and her knights arrive safely, but even here, a hellion attacks. Just as she is about to be swallowed up by this mud-like hellion, the seraph Zaveid arrives.

Upon learning that Maltran her teacher has been imprisoned by Bartlow, and is being crucified, Alisha and her subordinates sneak into Ladylake. Swearing that “no one must die,” she sprints through the city undauntedly even though Bartlow’s men obstruct her path. Meanwhile, Sorey and company pursue the dragon which is headed towards Ladylake, but the dragon picks up speed, making it impossible for Sorey to catch up. About that time, Lunarre comes to taunt Maltran, who smiles and retorts, “Alisha will not come here.”

With the help of his friends, Sorey purifies the dragon that resides inside the tornado headed for Ladylake. Alisha and Rose had absorbed some of the Malevolence from Sorey. This takes its toll and causes them to fall into a deep slumber, but they awaken with no ill effects. They resolve to continue to help Sorey as his squires. Meanwhile, Dezel battles Symonne who declares that her master, the Lord of Calamity, can no longer be stopped, and that the world will end. Symonne shows Sorey an illusion of the Lord of Calamity and despite feeling the impact of his overwhelming power, he decides to head for the northern land to find the Lord of Calamity.

Despite being thwarted by numerous dragons and the Malevolence, Sorey and company forge ahead and catch up to the Lord of Calamity. But after declaring that he is going to the center of the world, the Lord of Calamity disappears. Sorey and the others pursue him far to the north to the town of Meirchio where they encounter Grimoire of the Normin Clan. In town, Sorey ponders about the origin of the Malevolence, as well as the seraphim and the Lord of Calamity. After their short respite, Sorey along with Alisha, Rose and the five seraphim bid farewell to their friends who had traveled with them, and they set out to their final battle.

Sorey and company head for the north to find the Lord of Calamity. Alisha and Rose resolve to support Sorey as his squires and continue to practice armatization with Edna and Dezel. Meanwhile, Sorey reads the second Celestial Record given to him by Lailah, and finds entries about the north. In the northern land is the wellspring of a power of creation, and earthpulses connect the world to it. However, this land in the extreme north is not effective in spreading Malevolence. Sorey begins to ponder why the Lord of Calamity would go there. Then, Malevolence overflowing from the north attack Sorey and the others.

While in pursuit of the Lord of Calamity, Sorey and company are hindered by a huge army of dragons, but Dezel gives his life to thrash the dragons and open up a path. Sorey moves forward, determined that Dezel’s sacrifice will not have been in vain. Seeing an enormous amount of Malevolence flowing out of a cave, Sorey confirms the presence of the Lord of Calamity. Meanwhile, deep down in the large cavern, the Lord of Calamity has a confrontation with Maotelus, one of the Five Lords.

Sorey Armatizes with Zaveid, Edna, Mikleo, and Lailah, using all of their powers in an ultimate Armatization form in a final battle against Heldalf, who had become a monstrous beast. IN a hard battle, Sorey is able to defeat Heldalf, releasing him from the monstrous form, but he still remains the Lord of Calamity. The Malevolence uses the beaten Heldalf as a hollow vessel to use. Sorey promises to free him from this fate and attacks again, plunging the two of them into underground river. He sends the Seraphim away so he can fight him on his own. This sacrifice seems to have worked as the Malevolence has stopped and lowered to near non-existent levels around the world. Maotelus proclaims that this is the first time to truly purifying the world. Their battle done, everyone goes their separate ways. In the years that followed, Alisha becomes Queen of Hyland and brokers a peace treaty with Hylance. Lailah is revered by the people of Ladylake and the surrounding countryside, leaving on another adventure with a new Sheapard. Edna has become a Lord of the Land, with Zaveid serving as her bodyguard, and Eizen, who had regained some semblance of humanity with the lowered Malevolence. Rose and Alisha remain close friends. Mikleo is still exploring the world but receives a telepathic contact from Sorey. Mikleo finds Sorey alive and well, revealing that he was able to Purify Heldalf and left him in a far-off country town that was unaffected by his rampage. He and Mikleo decide to head home, hitting up whatever ruins they can find along the way.
