"Itadori Tōkan." It's not a question; more a statement. The source of the voice, a white-haired boy who seems to be about the same age as Tōkan, seems to have come from out of nowhere, he walked so quietly. He steps out into the light of the hospital reception where Tōkan was signing the last release forms for his grandfather's remains to be cremated. "I am called Fushiguro, from Jujutsu High. We need to speak. Now."
"That sounds entirely disgusting," says Tōkan, who can't help but feel fascinated by it. He extends it towards Fushiguro. "Take it."
Fushiguro nods, takes a step forward—
—his dogs immediately look up at them and start growling—
—his eyes widen and he jumps, pushing Itadori away and crying "Run!" just as some huge thing crashes through the celing on top of him.
Fushiguro's dogs finish the job of pulling Itadori and his friends out of danger, but given the size of the froglike creature now holding Fushiguro in its hand, that is but a temporary state of affairs. "Fushiguro!"
His hands are still free, so he punches his right palm then makes a "bird" shape with both hands while saying "Nue!"
The dogs start melting as soon as he does that, but the curse throws him at a wall and then blasts him with some electricity-themed beam of energy that punches him through said wall and out above a bridge connecting two of the school's buildings.
He falls, two stories rather than four.
He is rather undamaged even so, and the creature jumps through the hole it created with his body and lands on the bridge in front of him. The boy spits blood, trying to get to his feet and glaring at the curse—
—who gets very badly punched by Itadori. He lands on its head then swivels out away from it, kicking it one last time both to hurt it and to gain momentum.
"I said run," cries Fushiguro, trying to get up again and falling to hands and knees.
"I am not leaving you!" replies Itadori as he dodges one of the creature's arms and then grabs onto it to fling himself up into the air.
"Coulda said this earlier," Tōkan yells as he watches one of the creature's eyes, which he had just burst with a well-placed punch, reforms right then.
"Take those other two and—" Fushiguro collapses onto the floor, coughing blood. "—and run," he finishes, starting to drag himself away from the fight.
Anime plot.
Stupid anime plot.
He doesn't want to eat the finger, despite the obvious foreshadowing going on.
But, you know, he can only dodge the thing's swipes for so long, and then eventually he does fail and it grabs him and tries to eat him—probably it just wants to eat the finger in his pocket, but since his arm is conveniently free between two of the curse's outsized fingers, he can reach into said pocket and grab the finger once again and pop it into his mouth—
—(it tastes like soap)—
—and swalow it—
(Fushiguro has enough energy to facepalm. That idiot is going to diiiiiiiiiie.)
—and right on dramatic cue, Itadori breaks free from the curse's grasp, jumps from its face for some extra momentum, and then lands down onto it, ripping its face to shreds with his nails (?).
It dies. Unlike the times when he punched it and it regenerated, it dies.
One in a million chance. Or more, who knows.
Maybe he was onto something when he said this is the start of the anime plot.
Fushiguro thinks that thinking like that will get him killed and he would much rather not die. On the other hand, Itadori Tōkan has just eaten Ryōmen Sukuna's finger and rather than dying has become a vessel. The actual worst thing that could have happened today... did. If this is the start of an anime, he and Itadori were not the protagonists; Itadori was a short-lived character who gets possessed by a special-grade curse, and Fushiguro was a short-lived source of audience exposition who will soon be killed.
He laughs to himself, a little bit, weakly.
But his laughter is more than matched by the growing cackle coming from the body previously occupied by Itadori Tōkan. Said body seems to have acquired various markings, lines going along his arms and neck and face. Two lines on his face, actually, right under his eyes, are more than lines—they open, and reveal another pair of eyes. Ryōmen Sukuna laughs, to himself, at who knows what, the picture of a villain, examining his three-inch-long claws and his newfound body. "Ah, I had forgotten," he says, laughing so much he's almost doubling over. "The moonlight feels so much better on a body made of flesh."
He places both hands on his own chest, then shuts his fists around his shirt and with a single pull rips it off his body, showing off his (or Itadori's?) toned physique and, more importantly, the various lines, markings, tattoos adorning his torso. He laughs some more, looking to all the world like he is enjoying himself immensely.
Fuck. Fuck fuck fuck fuck fuck they are so fucked he is so fucked he is absolutely dead—maybe he can pretend to be dead, maybe he can run—he cannot take on a special-grade curse by himself, not as weak as he is, not when he was just thrown through a wall and down two stories, he is a sorcerer but he is not made of steel—
As if on cue, Sukuna swivels around to look at Fushiguro. "Thinking of running? Maybe I'll let you. Tell your sorcerer friends all about this and watch them try to stop me. Ah, it's been centuries, and I feel like a feast is in order—could you run if I pulled one of your legs off?" He starts taking steps towards the boy. "Your pick which. Just don't bleed out on your way back. Or do, I suppose it's up to you. I have children to kill and women to dismember and men to rape, or is it the other way around?" He grins widely, stopping just a few steps in front of the sorcerer. "Maybe both ways! All ways! I can do whatever I want—"
He slaps himself. "What do you think you are doing?" he asks, and this time he... does not sound like Sukuna. At all.
Sukuna's—Itadori's—that body's face goes through rather a lot of expressions, eventually landing on disbelief. "How... do you have control over this body?"
Now Fushiguro starts laughing again, and he's not sure if he should be crying instead.
Itadori places both hands on his cheeks and then slaps himself a few times. "My body. The eyes and tattoos and claws are cool and all but my body. Not yours."
