Curse Merchant

Mark Whitlock, an ordinary man with an encyclopedic knowledge of anime, finds himself inexplicably thrust into the perilous world of Jujutsu Kaisen. His only guidance? An innate understanding of his newfound ability: the 'Curse Merchant's Craft.' Mark can consume defeated curses, merging their raw cursed energy into inanimate objects and imbuing them with unique cursed techniques, essentially 'recreating' powerful artifacts from other fictional universes. Cheerful and opportunistic, he wastes no time setting up shop, offering his unique wares to the bewildered cast of JJK, all while subtly charming Maki Zenin. But as he floods Tokyo with items like 'Demon Slayer Corps swords' or 'Alchemist's transmutation circles,' Mark must navigate the escalating threats of vengeful curses and suspicious Jujutsu Sorcerers, all while trying not to completely derail the canon he loves, lest his profitable new life - and his chances with Maki - go up in smoke.
