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.
