Y/N earned himself a reputation 1000 years ago, many jujutsu sorcerers grew to be terrified of Y/N, often referring him as "The Hallow".
Having taken the lives of not only curses, but many jujutsu sorcerers and humans as well, he found himself on death row after being apprehended by the strongest sorcerers of that era. But the sorcerers were unable to kill him, instead having to curse and seal him into an object to avoid his wrath from releasing.

Fast forward to the present day, Y/N the Hallow is reawakened, and forced to aid the jujutsu sorcerers to receive a pardon.
And along the way, Y/N realizes he's not so hallow after all.
