In the wake of the first wave of shadow creatures, the world was plunged into ruin, a desolate yet enchanted wasteland. Humanity, driven underground, clung to survival while desperately plotting to reclaim their shattered world.But from the abyss of darkness, something miraculous stirred—a mysterious tree, shimmering with ancient power, appeared overnight. It chose only the strongest of heart, those with unbreakable will, gifting them extraordinary abilities. With these powers, humanity rose from the depths, waging war against the shadows.Yet beneath the surface of their heroic deeds lay a hidden rot. Corruption seeped into their ranks, and arrogance clouded their judgment. As their powers grew, so did the whispers of betrayal. The true battle may not be against the creatures lurking in the shadows—but against the darkness festering within their own hearts.A question lingers: When heroes fall, who will rise to take their place?

I died a virgin right after winning the lottery. Bad luck? That's my brand. So when a Grim Reaper offered me reincarnation with a gacha system for a “second chance,” I should've known better than to trust my luck.I rolled... an orc. The only fat orc in my entire tribe.The dungeon's demon lord gave me three years to lose weight or die. I trained harder than anyone, became stronger than most warriors in my tribe, but my belly stayed huge.With hours left to live, I made the dumbest decision of both my lives: if I'm dying anyway, might as well lose my virginity first.[Virginity Lost! System activated!][Obtain dungeon control upon complete subjugation]Turns out I was supposed to be a DUNGEON MASTER, not a slave warrior. And turns out I've committed the ultimate taboo: interspecies breeding, forbidden across all civilizations. Now I'm a fugitive.Humans, demons, and monsters alike want me dead. My own kind thinks I'm disgusting. I have absolutely nothing left to lose.Time to turn the worst gacha pull in history into the greatest dungeon the world has ever seen.

After 2000 years has passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “Inept”!?
