Genjo Sanzo

Tajima Sanzo, a 19-year-old gamer and anime fanatic, had the worst day of his life—kicked out of college in the dumbest way possible. But just as he wallows in despair, he gets isekai’d! Finally, his dreams of becoming an OP protagonist with a harem are coming true! …Or so he thought. Instead of a hero, Tajima is summoned as the 669th Demon King, the latest in a long line of losers who got steamrolled by the mighty hero. The once-feared Demon Kingdom? Gone. All that remains is a rundown shack in the middle of nowhere. An army of loyal minions? Nonexistent. And his legendary demon powers? A single skill called [Gacha OP]—which sounds amazing until he realizes... To activate it, he must perform the most humiliating acts imaginable. Now, armed with bottom-tier stats, a skill that’s more embarrassing than powerful, and a quest to make demons feared again, Tajima must find a way to rebuild his fallen kingdom. But with every Gacha summon more absurd than the last, and a world that refuses to take him seriously, will he become the greatest Demon King—or just a walking joke? One thing’s for sure: This is not the isekai power fantasy he signed up for.
