The Demon King, the titular threat of this dungeon, was defeated in a single strike, and the one who stood in his place was Demon Lord Aberis, the same man who had been manipulating Lord Reign.

“Lord Aberis is the son of Demon King Aberon?” I asked in disbelief.

“Ah… Deek!” He gave a smirk. “You’ve made it this far. It seems like I underestimated you. You’ve also started taking over the dungeon. Conquering dungeons… that’s something only my father has managed to do. You’re truly too dangerous to allow to live. Wait! What are you doing to my ex-girlfriend!”

His expression faltered as he pointed at the mermaid whose breasts were still in my hands. As if on cue, miasma suddenly leaked through the cracks of the door and then shot toward her. When it entered her, her expression changed.

“Aberis? My love?”

The miasma that had been affecting Carmine must have left her since it was in the presence of the true body.  It was the same way the miasma in Bernard had fled to Lord Aberis as soon as he entered. I immediately let go of her breasts and stood up, blushing, but she barely seemed to notice as her eyes were no longer on me, but the Demon PPrince.

“Tsk.” He made an annoyed sound. “I went to great effort to separate your karma from your body. You were very problematic during the early years of the dungeon.”

“P-problem?” She frowned.

“I’m sorry, did you ever think I loved you?” He chuckled. “I was just using you from the beginning. I instigated the war because father was too caught up on peace. It was only when the humans started slaughtering his people that he became more aggressive. I then proposed the marriage, the last chance to end the war amiably. Of course, father jumped on it. He wanted peace.”

“Of course, father had said when I got married, he’d fulfill any one request I made. So, when I got the gift, what I asked for was one strike. He would have outright refused something like demanding the country, but he was a prideful man convinced of his own strength. So, I took the opportunity to kill him. He was shocked, but he was also a man of his word. Regrettably, without the sword, I didn’t have the strength to defeat him in that strike. He… tried to destroy me.”

“That’s… what happened?” The mermaid’s expression went wide. “I heard that the Demon King killed you… I thought him an evil man… that’s why I… I…”

“You leaped into the lake and drowned yourself.” He sneered. “Fool.”

“So, what?” I interjected, as the princess was nearly in tears. “You failed to assassinate the Demon King, so you fled south, and then conquered Osteria with the plans of creating your own demon land?”

“It took quite a bit more steps than that, but basically.” He shrugged. “However, the one thing I didn’t have the ability to do that father did, was the ability to conquer dungeons. I could make my own, but it would take hundreds of years before they were powerful enough to help me. I couldn’t risk losing this dungeon, naturally, so I tried to create a new one. I even tried feeding my dungeon a king, but in the end, you interrupted those plans, didn’t you? No matter, I had other plans, and for those, you’ve been a splendid help.”

He held up the sword in his hands, inspecting the craftswork with a smile. He had finally gotten his hands on the Silvthril blade, just as he had planned from the beginning. I had walked right into his plans.
