I pledge my loyalty to the dark god who summoned me to this other world.

Karekusa Natsuki was an avid reader of more than two thousand otherworldly novels. Having longed to go to another world, his wish was granted when he was summoned by Lenartza, the God of Darkness. The successive Demon Lords had continued to lose to the summoned heroes, and the power of the demon race had declined. Currently, with no Demon Lord in place, it was said that defeat was inevitable even if a new Demon Lord were summoned. Therefore, Lenartza requests that Natsuki descend not as a Demon Lord, but as a Dungeon Master. He asks that Natsuki secretly expand the influence of the demon race without drawing attention. Natsuki accepts eagerly and descends as a Dungeon Master. Chapter One Complete. Proceeding to Chapter Two.
