Since nobody reads Jujutsu Kaisen anyway, imma not spoil this.
Oh. So that's why the poster of leak said "The Angel is basically a Nen Exorcist (you wont get the reference if you skip over Hunter x Hunter's minor subplot involving them)"
Ch. 145 plot summary.
Satoru Gojo is still trapped inside a prison realm. Now it's revealed that he was put in there through the "front door." Turns out, the All-Knowing Sorcerer Tengen has the "back door" and said that, it's very possible to get him out by opening the back door.
Problem is: the curse-technique-nullificartion items needed to open the back door has been destroyed by Gojo himself months prior to his capture. I.e, Gojo unwittingly screwed himself, much to the dismay of his students trying to rescue him.
But there's another possibility: find Angel, who has the ability to exorcise curses. Tengen said Angel is in the middle of a city-wide game of death.
So now our bois gonna join the game, get Angel and as many people out as possible.
OKAY ngl this arc has potential.
