Honestly, the way fanfic writers handle Gojo and Geto’s relationship is way more compelling than the canon half the time. It’s not just about romance, though 'GojouSato' is obviously massive. It’s about filling in that chasm of 'what could have been' between them, all that lost potential and ideological drift. A lot of fics treat their past friendship as this perfect, sun-drenched thing, which makes the fallout so much heavier. But the more interesting ones to me are the AUs where they never split, or where Geto returns somehow. Those stories dig into the mechanics of their power dynamic and whether their bond was ever truly equal. They’re both so catastrophically powerful and lonely, which creates this fascinating push-pull.
I also see a ton of exploration around the trio—Yuji, Megumi, Nobara. Fandom latched onto them as this found family unit incredibly fast, which says a lot about how well their dynamic works. The fics range from fluffy slice-of-life stuff to really dark explorations of survivor's guilt, especially after Shibuya. The Megumi/Yuji ship has a huge following, obviously, but I think the platonic friendship fics often hit harder emotionally. Writers get into the quiet moments, the shared burdens, the way they communicate without words. It feels authentic to the source material's tone, where the bonds are forged through shared trauma.
Then you have the wilder, niche ships like Todo/Itadori, which are built entirely on Todo’s unshakeable, bizarre brotherly devotion. Those fics are either hysterically funny or surprisingly tender, reframing his intensity as a form of protective love. The beauty of 'Jujutsu Kaisen' fanfiction is that the source material provides such a rich, traumatic sandbox. Relationships aren't explored in a vacuum; they're tested by curses, loss, and the constant threat of death, which forces writers to get creative with how connections survive, or don't, under that pressure. I’ve stumbled on a few crossovers with 'Chainsaw Man' that explore this even further, throwing characters into even more nihilistic settings just to see what bends and what breaks.
