​I Accidentally Bound the Devil to My Apartment, and My Magic System is Bankrupting Me

Zack’s life plan was simple: work at the local game store, build top-tier trading card decks, and avoid real-world responsibilities at all costs. But when a spilled energy drink accidentally summons Lucifer, the Supreme Lord of the Underworld, into his living room, his peaceful slacker existence goes up in flames. ​Fortunately, Zack manages to bind the terrifying (and deeply arrogant) Archdemon to a cosmic contract by defeating her in a 14-0 game of digital car-soccer. ​To keep her from incinerating him, Zack uses his first wish to strip her of her demonic powers, trapping her in the frail, deeply uncoordinated body of a five-foot-two mall-goth. Lucy is furious. She is territorial. And she is completely utterly defenseless when the Heavenly Council and the Underworld Tribunal team up to assassinate them both for breaking cosmic law. ​To survive the impending holy war, Zack unlocks a LitRPG System of his own: The Grave-Tender's Ledger. It’s a powerful summoning class, but it comes with a catch. To cast spells and summon ethereal monsters, Zack has to permanently sacrifice his own physical belongings. ​Now, teaming up with his tank-main best friend, a hyper-competitive online healer, and his incredibly high-maintenance tsundere roommate, Zack has to fight off angelic hit squads and demonic bounty hunters. ​He just hopes he can save the world before he runs out of household appliances to sacrifice.
