In this world, humans, beastmen, and elves exist in a classic fantasy setting, opposed by the Demon Race. A war to decide the fate of man and demon has begun. The Hero Lang and his party—Achimene, Dahlia, and Node—were hailed as the strongest party in human history. They finally reached the Demon Lord's throne. However, the battle ended in the Hero's defeat and the victory of Demon Lord Guest. The Demon Lord surpassed the heroes in both wisdom and strength. The Hero was sent back alone via teleportation magic by his comrades. The remaining members were incapacitated, and the Demon Lord decided to take them as prisoners. This is the story of what happened after that battle.
