Extra's Harem: Invincibility Starts with Marriage and lots of Children

Hey, you—yeah, the one scrolling past like this is just another trash-tier harem power fantasy. You probably think you’ve seen it all, huh? Bet you're sitting there judging with Cheeto dust on your fingers and nothing better to do. But let’s get real—what if you, the background NPC of your own life, got a second shot… and this time, you made the whole damn world kneel? Ryan was just like you. An office drone with zero plot armor and a routine so boring even death skipped him—until it didn’t. A hot reaper—because of course she was hot—accidentally kills him. Her punishment? Ten minutes of no powers. His reward? A smirk and the same level of respect your Tinder matches give you: zero. So what did he do? He yeeted both of them into the Reincarnation Pool. Yeah. Petty, chaotic, unhinged. And glorious. Now, he's reborn in a steamy power fantasy novel—Invincibility Starts with Marriage and Having Lots of Children. His role? A disposable body double, set to die in place of a ducal prince at the hands of the woman whom he is about to marry. His plan? Burn the script, steal the throne, and make every heroine call his name in bed and on the battlefield. He remembers everything. The reaper’s stuck with him. And the world runs on power, bloodlines, and pleasure—and Kyle (yeah, new body, new name, same extra) is about to break it like your last failed resolution of this year. A system that rewards marriage. A domain that grows with every wife. A nobody who’s done being forgettable. It’s not just revenge. It’s a hostile takeover—with moans, absolute power and your support.
