Kikansha no Mahou wa Tokubetsu Desu

Ten years after the appearance of the Labyrinth of Shadows, an entity belonging to the Shadow World, all of humanity was decimated. The last six survivors attempted an unprecedented assault to destroy the source of the Labyrinth. As the battle against the Dragon was coming to an end and the six had managed to defeat it, the heart of the Labyrinth was blown away by an explosion, taking Desir Herrman, his companions, and consequently the world to its end.

However, it was not death that Desir found before him in that explosion, but the world, thirteen years earlier... When he was about to enroll in the most prestigious magic academy in the country of Havrion.

From that moment on, Desir Herrman has three years ahead of him before the appearance of the Shadow World dimension. Three years to gather powerful allies and change the tragic destiny towards which all of humanity is heading.
