Jujutsu Kaisen X OC (The Red String of Fate)

The Brothers

Sadako's POV

"Kugisaki, avoid contact with his blood," Itadori warns, anticipating the danger.

"I know—"

Activating Rot Technique, Maximum: Wing King, Big Bro unfurls insect-like wings forged from his poisonous blood, preparing to unleash his deadly assault.

"Run. Keep close to me," Itadori instructs, urgency coloring his tone as they flee from the oncoming threat. Lines of toxic blood snake after them, forcing them to sprint for their lives.

"Kugisaki, can you run faster?!" Itadori queries, concern evident in his voice.

"I can't!" Kugisaki stumbles, unable to keep pace, prompting Itadori to scoop her up and carry her, utilizing his incredible speed to escape.

"Ah... Yuuji~~~?" I can't help but gush like a smitten schoolgirl. "How old is he again? Such terrifying speed, and carrying Kugisaki as well. Simply remarkable."

"He's 16," Gojo responds nonchalantly.

"He's strong, handsome, kind, and a bit dumb, making him a truly remarkable lover," I continue, lost in admiration.

"I'm right here!" 

- Sukuna

"You can shove it,"

- Sadako

Zigzagging through the forest, Itadori deftly evades their pursuer, eventually losing them near a highway. As Kugisaki expresses her gratitude, they are suddenly ambushed by Lil Bro.

Realizing they've been outmaneuvered, Itadori comprehends that Lil Bro took a more direct route to cut them off.

While Kugisaki tends to Itadori, she is caught off guard by Big Bro's wings, striking her from behind. "Ah, finally home," Gojo sighs in relief as the situation stabilizes.

"Your students are on the brink of death, and you're just chilling at home?! What's wrong with you?! Can't you at least lend a hand?" I chide Gojo, exasperated by his nonchalance.

"I remember now! Satoru!! Want to watch something? The thing I've been checking out," I inquire, recalling one of the cursed techniques from my clan.

"Couldn't you have remembered that sooner?" Gojo responds, unamused, while I giggle in response. "It just came back to me," I offer innocently.

The technique in question was called "Dreamweaver's Gaze," an extraordinary ability that allows me to share my visions and experiences with others, transcending the limitations of time and space.

"What a remarkable technique. Truly rare and revered," Gojo remarks in admiration. "Can you see clearly?" I ask, rubbing my eyes before reopening them.

"Yeah..." he confirms with a nod.

Meanwhile, having caught up with his adversaries, Big Bro elaborates on the properties of their acidic blood. "Don't worry. My brother's blood has different properties than mine."

"Even my blood isn't lethal unless it covers your entire body. But it's going to hurt like hell... Rot Technique..."

"Decay."

With that, he activates Rot Technique Decay, manifesting floral patterns across the areas of Itadori and Kugisaki's bodies that were struck by the blood, signifying the onset of decay.

"So it's poison after all?!" Itadori was concerned, but Big Bro clarifies that it's actually a decomposing agent affecting their bodies. 

'Surprisingly good news!'
