My Family Auctioned Me to the Demon Lord, So I Seized the Entire Ducal Estate Instead.

      My dad sold me to the Demon King for 1 copper coin just to pay my brother's fake dragon-blood debt.
      Guess what? The idiot forgot he ALREADY mortgaged me 3 years ago! 💀
      Now, I'm marching back to seize our entire Dukedom —— as the Demon King's official legal proxy! 😈👑
      Unfortunately, my family is a walking financial disaster.
      My brother's legendary dragon scales? Leased. My sister's upside-down magic tower? Three months behind on its utility bills. Even the very foundation of our manor is collateral.
      And my father? He's currently trying to destroy the evidence with a sledgehammer.
      But that's when I discover something buried beneath our estate: one of the Nine Genesis Nails, ancient instruments holding the entire world together.
      Turns out, the world's been in default for 4,000 years. And the Treasury's top liquidators are coming to collect.
      Their solution? Repossess all nine Nails, dismantle the planet, and sell the pieces.
      Well, I've got a cursed ledger, a demon king's power of attorney, an increasingly ridiculous collection of seized assets, and absolutely no intention of letting anyone liquidate my customers.
      If the apocalypse is just another foreclosure, then I guess it's time to audit the end of the world. 💀
