Some villian stsg headcanons:

So I haven’t seen more ppl talk about this but what if Geto convinced Gojo to join his cause… BUT it’s not like Gojo and Geto go on a rampage together. Oh no no no no, Geto asks Gojo to stay back at Jujutsu High and let him do the dirty work. Gojo’s job is more like infiltration, he has to clear records of Geto’s murders and whereabouts, provide the higher ups with false information and keep getting money from his own clan to fund Geto’s cult. Gojo works as a jujutsu sorcerer but gives Geto information about his missions and lets Geto consume the Special Grade curses he is assigned to exorcise. So they basically an unhinged couple where one is running a cult and going on a murder spree while the other one is doing the insider job and covering up for the other.
