Majima Takahiro and his friends survive the ordeal inside the labyrinth and learn the truth about the world. Their very existence threatens to trigger another Grand Calamity, a world-ending event. Fortunately, they also possess the knowledge to preempt such a catastrophe. Set to return to Aker to accomplish that goal, they are forced to go back to the capital when they are informed that the world faces more than one apocalyptic threat.

The search for the Treasurebeast Orbs scattered across Caldina leads Hugo and AR-I-CA to the great city of Cortana. This cosmopolitan center of commerce is no doubt a jewel of the desert, but few things in this city have as much value as the Orb said to have arrived here—one said to bestow the coveted power of immortality. With such rumors spreading far and wide, it would be foolish to think that Hugo and AR-I-CA would be the only ones in pursuit of this boon. A knight of ice, a soaring songstress, a bloodstained child, and a Master of death converge upon the poisoned oasis, heralding the coming of a brand new possibility.

Escorted by the elven knight Shiran, Majima Takahiro and Lily arrive at a fortress within the monster-filled forest. There, they meet members of the first expeditionary force and Takahiro’s best friend Mikihiko. Not everything is as it seems, however. As the two of them begin to learn more about this world and its inhabitants, they must closely guard their secrets from all those around them. Meanwhile, Gerbera, Rose, and Katou Mana remain hidden in the forest. They continue to keep a watchful eye on the fortress, but an unexpected event befalls them...

After arriving safely in the imperial capital, Takahiro meets the exploration team and receives an invitation to join them. However, with Mitarai’s objection and the discovery that Okazaki was one of people responsible for Draconia’s destruction, Takahiro decides to turn it down. He then returns to his room to comfort Mana over her argument with Mitarai, after which the entire group is suddenly whisked away by the power of the Fairy Ring. Takahiro finds himself stranded with Mana, separated from the others in a mysterious and monster-infested labyrinth. Takahiro’s servants are scattered throughout the rest of the deadly maze, and finding their way back to his side won’t be easy, for more than just monsters lurk in these winding halls...

After being teleported to a fabricated world, Takahiro is isolated from his companions. Mikihiko suddenly appears and stabs him, abducting Mana in the process. Takahiro steels his resolve to go rescue her. The stage is set as the Holy Order pits the two best friends against each other in a battle to the death. Meanwhile, things are on the move back in the capital as Kei makes an unexpected discovery, and Mana finds herself faced with the mastermind behind the whole incident, Marshal Harrison Addington, the knight among knights.

Takahiro’s group finds themselves in a hopeless predicament, facing off against the Skanda Iino Yuna’s overwhelming power. But thanks to Mana’s sacrificial play, they successfully overcome Iino’s strength. However, as a result, a landslide splits the party in two and half the group is washed away by the river raging below the cliff. When Lily manages to find Takahiro and the others who were separated, yet another cheater launches a sudden attack on them. With Takahiro’s forces scattered and exhausted from the previous battle, can he fend off this mad warrior?

After forming a contract with the Misty Lodge and returning to town, Takahiro and his group once more bump into the cheater Fukatsu Aketora and his traveling companion Thaddeus. The circumstances of their encounter lead to Thaddeus revealing that he is actually a dragon. Thaddeus’s goal, the reason why he’s in town, is to find a stray dragon who has escaped their settlement before any human casualties lead to inevitable repercussions. Agreeing to help, Takahiro embarks on a path that will teach him much about this world and harden his resolve for the future.
