I personally head canon that Sanemi despises the sound of chewing / loud smacking.
So after you two get into an argument and aren’t speaking, you’ll purposely start chewing gum and make a point to chew it as loud as you possibly can.
I’m talking open mouth, loud chomping while just glaring at him. And you can tell he’s getting worked up because his ears are turning from white to pink to bright red.
You keep going until he finally snaps, shooting up from the couch and stomping over to you. Sanemi knows how you work, he knows you only do this to get under his skin.
So his calloused hands are on your cheeks, squishing them hard so you stop your godforsaken chewing.
He’s glaring down at you, lips pulling into a scowl as his nose scrunched. “You’re fucking cruel, ya know that?” But he has you in a position where you can’t speak.
“Gum. Now.”
So you stick your tongue out, the wad of gum present as he uses his free hand to pluck it from your mouth and toss it in the trash. “Fucking childish shit, you know that?”
But now his other hand is on your waist, his thigh is squeezing between your own and forcing them apart. “Such a fuckin brat, ‘s annoying” except, his lips are hovering centimeters above yours.
“You need to be put in your place, sweetheart.” But he’s still got his hand on your face, you can’t do anything but nod in response to his words. “Oh? You agree? You want me to teach you a lesson, hmm?”
Sanemi is grinning now, any ounce of anger from the fight is gone. Which had been your goal from the very start.
Idk I guess I’m just missing my baby daddy since I’m giving y’all two headcanons in one night - May 🩵
Villain Nanami but instead of joining Geto, he never made the phone call to Gojo after 3 years and just--straight up broke and killing the higher ups. Of his company, not jujutsu society rip
He then proceeds to work as a merc similar to Toji but not really because he aint a bum lmao
Everyday Gojo thinks about the irony about how the only people who could really touch him are both cold blooded killers that have an agenda against everything he stands for, aka jujutsu society rip
I imagine though that gojo tries talking to him similar to geto. Things go... a bit differently compared to what happened then, nanami revealing to him that hes not against jujutsu society as a whole, just the way its run. After that bombshell, gojo tries every encounter they get (i imagine they have a lot of those thanks to the higher ups sending him to hunt nanami down) to get him to stop his murderizing ways and find a different way. He keeps failing, but nanami always assures him that hes on gojos side as he wants to reform and help their society
I can actually see him helping subtly with getos defection. Since hes a merc and sorcerer for hire, i can see gojo hiring him to do things he cant since hes always stretched too thin. Like keeping tabs on geto, sabotaging his efforts to collect more curses, etc etc. Ofc he still murderizes people and other targets though, he might be a bit of a jujutsu vigilante but hes still a blade for hire
I realize that ive just turned nanami into Jason Todd Red Hood.
ANYWAYS--
With Kento being outside interference wholly focused on helping gojo and doing his own thing, id like to think theres a good chance they could stop the Night Parade from happening. With his time working in that profession, i imagine that he develops his technique much further and has a more thorough understanding of the other aspects of jujutsu like barriers, and simple domains. Add to that his lack of a moral code and shit about murderizing people, and i genuinely think that theres a good chance of it either not being as bad as in canon or just. Straight up Not Happening. The Night Parade, i mean.
I can see nanami, after learning of what getos planning, coming in and systematically dismantling each and every one of his plans via murder. And gojo would trust him, since i imagine at this point, nanamis serving as his eyes and ears on geto, and nanamis been helping him deal with all the troubles hes been causing. So ofc, while none the wiser on as to how nanamis gonna do it, he trusts nanami to execute on his plan.
So off he goes, eliminating or killing curse users that might join geto, defeating or at least weakening higher grade curses that geto might have his eye on, and systematically eliminating getos different cult strong posts via murdering important members and whatever of getos inner circle he can reach. At a certain point, i can see geto getting wind of what nanamis doing or at least realize that nanamis the one behind the fuckery happening with his plans. I see him being... unsure on whether or not to be furious or amused, and a bit more research later, discovers that hes a bit of a sellsword. A look through his client list and he discovers that his most recent hires are from JujuTech, and quickly assumes that gojos the one hiring nanami to sabotage him. He isnt exactly wrong, but he isnt exactly right either. Hes only hired to keep watch. Doesnt say that he cant meddle though.
Geto then gets it into his head to use nanamis for hire status against gojo, and hires him to work for him instead—saying that he's gonna pay him double whatever gojo pays him. Nanami accepts. Hes quite literally being paid to betray gojo, doesnt mean he cant betray them back for free though. Geto, quite literally, put a fox in a chicken pen.
Yes, he still does as Geto wishes—targeting JujuTech students and trying to kill them (his attempts are so half hearted though that he just ends up decommissioning them for a bit), targeting and attacking clans (this, hes perfectly okay with not holding back—helps both geto, him and gojo anyways if a few more of these fuckers died), and locating and not killing strong curses (dont mean that he cant leak their existence to Gojo though). Nanamis running the riskiest double con here because hes now officially working for geto, but still helping out gojo LMAO
I could go on but ive lost steam rip-- its a poggers thought experiment thoughk
It is terribly, distantly funny though. In a way that's not funny at all. Like, at least the question of "is my mother a bad person?" can finally be put to genuine rest for all of eternity, and I don't have to grapple with the back-and-forth teetering. I wanted objective, concrete proof—well, here it is.
