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.

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...

A giant army of monsters suddenly attacks Fort Tilia. Among all the chaos and death, Takahiro and Lily must decide whether to reveal their secret, and invite suspicions that they were behind the entire attack. But if they don’t act, their new friends in the fortress will be in danger! Meanwhile, the cheaters of the exploration team, Juumonji Tatsuya and Watanabe Yoshiki, prepare a counteroffensive plan to repel the invaders alongside the army. However, at the final hour, the unimaginable happens. None can peel their eyes from this development!

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.

After a desperate struggle with the Maclaurin Provincial Army, Takahiro, his servants, and the villages’ elves manage to escape their pursuers. His group then moves to Aker’s capital at Prince Philip’s behest so that they can form an alliance. They are far from safe, however. Not only do they need to fend off further threats from Margrave Maclaurin, but now that their secret has been exposed, they must find a way to get the general populace to accept Takahiro’s servants. One day, during their stay at Aker’s royal palace, Iino Yuna unexpectedly visits Takahiro as the church’s envoy to invite him to the imperial capital. Concerned about the unrest spreading through the people, the church wants to discuss an armistice with Margrave Maclaurin. Can Takahiro create peace and happiness for those he holds dear, or will his existence destroy the very foundations of this world?

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.

The monster attack has left Fort Tilia in ruins. Since they can no longer defend the fortress or stay there in safety, Takahiro and the remaining survivors leave to escape the Woodlands. Their destination is the Third Company's home of Aker. Trouble follows close behind them, though. The Skanda, a cheater with overwhelming power even among the students, receives news that Takahiro might've been the one behind the monster attack. Thus she begins her pursuit, ready to bring him and his monsters to justice.
