Exiled Duke Conquers the Dungeon! ~After Betrayed by His Fiancee and Being Banished to the Labyrinth of Death, the Duke Unleashes His Talent as a Monster Tamer and Dominates All~

Glare, the eldest son of the Duke of Mizail from the Evegrand Kingdom, had been living a prosperous life as the heir of a great noble family. However, his life turned upside down when he witnesses the affair between his fiancee, Sophie, and the crown prince.

Enraged, he finds himself waking up in a carriage after being knocked unconscious by the furious crown prince. With his hands and feet bound, he receives a de facto death sentence. “You are a traitor who raised your hand against His Royal Highness the Crown Prince. Therefore, you are hereby sentenced to solitary confinement on the second floor of the Labyrinth of Death. Your family, the Duke’s household, has already disowned you. There is no escape for you.”

The Labyrinth of Death. It’s a notorious dungeon within the Evegrand Kingdom, a den of ferocious monsters and traps, with no one having fully conquered it yet. Even S-class adventurer parties have only been able to reach the 10th floor. There is no way that Glare, a layman who is not even an adventurer, can survive there with only minimal equipment and food. Despairing of the crown prince’s scheming to use him as monster bait to hide his own disgrace, he soon encounters a ferocious green slime and faces a crisis of life and death.

In that desperate situation, he awakens his talent as a Monster Tamer and begins to build the strongest monster army. He sets out to conquer the Labyrinth of Death as the strongest adventurer. On the other hand, the crown prince and his former fiancee find themselves increasingly cornered by Glare’s actions.

Meanwhile, in the capital city, those who adore Glare are also moving to rescue him…
