On their way to the class field trip, a mysterious young boy claiming to be a god appears before Ard, Ireena, and Ginny. After making a mysterious request, the god sends the three of them back into the ancient era when Varvatos was active. After deciding to try and gain an audience with Varvatos in order to change their situation, they encounter a woman fighting monsters in a field. Then a figure they all know very well appears before them...

After receiving the Demon Lord's declaration of war, Varvatos decides to take him down. Ard feels history changing around him, but he's unable to predict where it will lead. While lost in thought, the Demon Lord suddenly appears before him. Ard is shocked when he introduces himself as Disaster Rogue and reveals his true identity. The Demon Lord then offers him a proposal.
