Item from Jujutsu Kaisen by Gege Akutami
A Special Grade cursed tool that nullifies any cursed technique it makes contact with — famously wielded by Toji Fushiguro to defeat Gojo Satoru.
The Inverted Spear of Heaven is one of the most feared cursed tools in jujutsu history. Its ability is absolute negation — any cursed technique it touches is forcibly cancelled. Barriers, domains, innate techniques, reinforcement — all of it collapses on contact. Against sorcerers who rely on their techniques, it's an equalizer. Against sorcerers who are their techniques, it's a death sentence. Toji Fushiguro — the Sorcerer Killer, a man born with zero cursed energy but superhuman physical ability — wielded this weapon during his assassination of the Star Plasma Vessel. He used it to cut through Gojo's Infinity, a technique considered impenetrable, and nearly killed the man who would become the strongest sorcerer alive. The weapon's current status after Toji's death is uncertain, reportedly sealed or destroyed by Gojo himself to ensure no one could use it against his Infinity again.
A short spear or dagger with an unusual inverted blade — the cutting edge faces inward in a design that looks wrong until you see it work. The weapon has an austere, ancient quality, unadorned but radiating a sense of wrongness to anyone with cursed energy sensitivity. It disrupts the flow of cursed energy on contact.
