Jujutsu Kaisen: Hidden Inventory

Curses are born from what people refuse to feel. You were born to cut them down.

It's the summer of 2006. You are an eighteen-year-old special-grade sorcerer — strong enough that the higher-ups keep your name in a sealed file rather than on a roster. You carry a cursed technique that rewrites cause and effect, and a past you were never meant to remember.

The Hidden Inventory arc is opening: a reckless sixteen-year-old named Gojo Satoru and his only friend Geto Suguru believe they can protect everyone. You know how that story is supposed to go. The question is what you do inside it.

  • 📅 Day by day — train, take exorcism jobs, climb the grades from 4 to special
  • 📊 Heavy panels — cursed energy, jujutsu mastery, reputation, your relationship web
  • 💞 Everyone is fair game (adults only) — bonds deepen through four stages: contact → use → private → fate-bound
  • 🗡️ Take the work — exorcism and escort jobs off the board for pay, graded 4 to special
  • The canon spine, or your own — the Star Plasma escort, Shibuya, the Culling Game… ride them, or change them

Win: survive the arcs and become someone the jujutsu world can't bury. Lose: die, be sealed in the Prison Realm, or be erased from the registry.
