Maou-sama no Machizukuri! ~Saikyou no Danjon wa Kindai Toshi~ (Novel) Manhua

Title: The Dark Lord's Redemption In a realm where fear shrouded every corner and despair reigned supreme, there existed a Demon Lord named Azazel. His name struck terror into the hearts of even the bravest warriors, his labyrinth a place where hope withered and died. Yet, within Azazel's blackened soul, a tiny ember of compassion flickered. It whispered to him in the dead of night, haunting him with the suffering of the humans trapped in his labyrinth. It was a feeling he couldn't shake, a feeling that challenged everything he thought he knew. Driven by an unexpected surge of guilt, Azazel made a decision that sent shockwaves through the demon realm. He would defy his nature, he would defy destiny itself, and he would bring light to the darkness he had created. As he toiled to build a town within his labyrinth, a town filled with warmth and joy, whispers of his madness spread among the other Demon Lords. They sneered at his folly, they scoffed at his weakness, and they vowed to crush his rebellion before it spread. But Azazel persisted, his determination unyielding as he watched the humans in his town blossom under his care. Their laughter echoed through the once desolate halls, their smiles a testament to the power of redemption. And as he witnessed their transformation, a change stirred within Azazel. The icy grip of despair that had long held his heart began to thaw, replaced by a growing sense of fulfillment he had never known. In the end, Azazel's town stood as a beacon of hope in a world of shadows, a testament to the extraordinary power of one demon's redemption. And as he gazed upon the faces of those he had saved, Azazel finally understood the true meaning of his existence - to bring light to the darkest corners of his world, and to prove that even a Demon Lord could find his way back to the light.
