Accidentally Married to the Demon Lord’s Daughters

When Owen Mercer, a burned-out gig worker with an encyclopedic knowledge of fantasy games, dies in the most embarrassing way imaginable, he expects oblivion—not to wake up in a summoning circle beneath a collapsing castle. The cult that meant to summon a legendary Hero got the wrong man, the wrong century, and very much the wrong paperwork. Thanks to a glitched celestial contract, Owen arrives with a broken skill called Shared Destiny, which lets him copy, amplify, and combine the talents of anyone bound to his party… or his household. The catch? Through a magical loophole, he is instantly and legally engaged to three terrifyingly beautiful women who all claim descent from the missing Demon Lord.

As human kingdoms prepare for war, monster territories splinter into chaos, and every church in the continent labels him either Savior or Antichrist, Owen decides on the most reasonable plan possible: avoid destiny, renovate the ruined demon frontier, and build a neutral city where humans and monsters can get rich instead of get slaughtered. Unfortunately, his accidental fiancées include a battle maniac, a smiling schemer, and a sleepy archmage with enough power to erase mountains. Between fake marriage politics, absurdly overpowered crafting, dungeon farming, and the inconvenient possibility that the old Demon Lord may have been framed, Owen is about to turn the apocalypse into the hottest new kingdom in the world.
