I just woke up from a dream in which I had watched an entire episode of Jujustu Kaisen that, presumably, doesn't and won't exist, so I'm compelled to share. I'm anime-only, btw.
Essentially, Megumi summons a curse to help him fight against an opponent of special grade level, but the curse is too weak. In a twist, turns out the curse summoned is only the host to a more powerful curse living inside it (didn't "catch" the name, but the outer curse looks like the onryo Sadako while the inner curse looks like a black mass of tentacles with a mouth). As the outer curse dies, freeing the inner curse (let's call them X), the opponent is quickly defeated and consumed, then spat back out. Despite having been technically summoned by Megumi, X actually wants to take his body over as well - the protagonist knows this and tries to stall for time, but in the end loses a battle of wits and gets his body partially controlled. That's when Yuji shows up. The previous enemy, now controlled by X, attacks him for a bit, they have a quick chat and he backs off - X-controlled Megumi attacks instead. As they talk, there are a few references to other anime (one of X's power has something to do with copying fictional media. He references being able to defeat Bleach's Kenpachi, catching any pokemon and some other jokes). At this time, X has housed himself inside Fushiguro's leg, heavily deforming it. X-Megumi prepares to use a final attack to defeat Yuji when, in the blink of an eye, the hero moves behind them with a classic samurai-style slash motion, Sukuna's tattoos flash in and out of existence, and X is resting in Yuji's hand, as he exclaims (in a somber atmosphere) "your curse only changes the body, unlike Mahito's". There's a brief glitch effect during which Yuji is swapped out with Bleach's Kenpachi saying "easy", and X gets crushed like an egg. The rest of the dream episode is largely setup dialogue.
Now I'll have to live the rest of my life knowing there's a weird made-up episode I'll never watch again. How crazy is that? By the way, the animation quality was a 10/10.
So well thought out, you truly must've spent a long time sitting on that one.
