Character from Chainsaw Man by Tatsuki Fujimoto
A skeletal devil bound to a nail-like sword — stab a target enough times and the Curse Devil manifests to kill them. Each use costs the wielder years of their lifespan.
The Curse Devil's contract is brutally transactional: the wielder stabs a target with the nail sword, and after sufficient stabs, the Curse Devil materializes to execute the target with certainty. The price is the wielder's remaining lifespan — each use visibly ages the user. Aki used it knowing he was shortening his life, a sacrifice that underscored his obsessive need for revenge against the Gun Devil.
A towering skeletal spirit with elongated limbs and hollow eye sockets, wreathed in dark energy. Manifests briefly to crush and kill the designated target before vanishing.
