Imagine kicking the bucket right after hitting the jackpot. That's the kind of luck that plagues our protagonist. When a Grim Reaper offers him a shot at reincarnation with a tempting gacha system, it seems like a dream—until he rolls the character. He's reborn as an orc. Not just any orc, but the tribe's resident chubby outcast, saddled with an impossible ultimatum from the demon lord: slim down or face oblivion in three years. Through relentless training, he becomes a powerhouse, yet the weight stubbornly clings. Facing death, he makes a desperate, life-altering decision that unlocks a hidden power. Suddenly, he's not just an orc, but a Dungeon Master, thrust into a world of interspecies taboos and hunted by everyone. Now a fugitive, reviled by his own kind and sought after by humans, demons, and monsters alike, he's hit rock bottom. But from the depths of despair, a spark ignites. What if this "worst gacha pull in history" could become the foundation of the most epic dungeon ever conceived? Get ready for a wild ride in *Lewd Dungeon Master: This Orc Is Too Damn OP!*, where one orc's misfortune might just reshape the world, one dungeon room at a time.
