Volume 9 of Jujutsu Kaisen is set to come out within the next couple of days on April 6th. The description of the book is as follows:

"Satoru Gojo and Suguru Geto have been assigned a mission to escort the Star Plasma Vessel to Master Tengen. When they’re ambushed by Toji Fushiguro, a mercenary known as the Sorcerer Killer, will Gojo and Geto survive? And will this be the turning point where Gojo becomes the world's strongest exorcist while Geto embraces a life of ruin and rebellion?"

Based on the description alone it seems that it is a very actioned pack volume for the manga. Can't wait to see and read what these characters have in store!
