"DREAM TECHNIQUE: DROWSY SPELL, maximum output!" a blast came from you and hit the smaller enemies, causing them to slump over in a deep sleep. "and now you.." you turned towards the larger curse. it rushed at you. "dream technique: counted she- huh?!"

the curse suddenly had a huge hole in its chest. it fell over, dead. "sorry, were you saying something, brat?" a familiar spoke, cockiness clear in his tone. "what the hell, sukuna?? i had it handled!" you exclaimed as the male approached you. "yeah, sure you did. you didn't even try to fight it without your technique. plus, you were taking too long and i want food." sukuna replied, shoving his hands into his pockets.

"what're you, a child??" you asked, offended and angry. had he really decided to jump in for food?? "what're you, an idiot?" he mocked. you growled, grabbing onto his face and pulling at his cheeks. sukuna grabbed onto your hair and pulled at it. "fuck you, fuck your stupid face marks-!" "let go of my fucking face, you brat!" "that remark didn't even make sense in context!" "THAT'S BECAUSE YOU'RE A DUMB IDIOT!" "KILL YOURSELF-!"

☆☆☆

sukuna rubbed his now bruised cheeks, glaring at you. "you really are annoying, you know that?" "call it karma" you retort as you ate your takoyaki. he scoffed, starting to eat his udon. "just saying guys. why don't you two use that same energy for hate, but for love?" yuji questioned, earning grumbles from the both of you.

yuji had followed sukuna when he heard that he'd be going to fight a curse where you were. he arrived just before the two of you started using your techniques on each other.

"i would never love that menace" you said, pointing to sukuna with your takoyaki. "he's a menace with a good heart, y/n" yuji replied. while you weren't looking, sukuna ate the takoyaki that you had pointed towards him. "sukuna!" "hm?" you gasped as you noticed that the takoyaki was gone. you looked towards sukuna, who was chewing. "must've been the wind" "OH YOU SON OF A-!"

yuji held you back, which made sukuna laugh. "calm yourself, brat, don't get feral now!" he teased, continuing to laugh. "i'll show you fucking feral, ryomen sukuna!" "let's just calm down!" "DREAM TECHNIQUE-!" "Y/N, NO!"

"there's a special grade curse downtown. considering that you're our most powerful fourth years, we're sending you two out" yaga spoke. you nodded as sukuna scrolled through his phone, seemingly bored. "sukuna" the principal said sternly. "i heard you!" sukuna replied. "..you're both dismissed." you both stood and left the room, heading to the location of the curse.

you eventually arrived. "abandoned hospital..of course. it's pretty small compared to other ones, though" you mutter. "why don't you stay out here like a good brat and allow me to handle this?" sukuna spoke, grinning. "do i look like a dog to you?" you retorted. "yes, you're practically identical to one."

you huffed as the two of you entered the building. "i'll handle the second floor, you stay down here" you told sukuna, who rolled his eyes in response. you walked up the stairs, looking for any signs of the special grade.

sukuna walked around the lower floor, running into a couple grade 4 curses. he decided to ignore them, since they weren't worth the effort nor time. he pulled out his phone. after about ten minutes, sukuna noticed the silence. wouldn't he at least hear your footsteps? or your annoying ass voice? he glanced towards the steps. "..nah" he muttered, looking back at his phone screen.

a feeling nudged at him, but he ignored it. worry filled his mind, but he ignored that too. after mere moments, he growled and turned to the stairs again. "why so silent, brat? don't tell me you fell asleep on the job!" sukuna joked. instead of your sassy response, he was met with silence. he grumbled to himself as he began to ascend the stairs. "if this is some stupid prank, i'll kick your ass-!" sukuna's eyes landed on your unconscious body. his angered expression was replaced with one of surprise and concern.

had he completely tuned you out? or was the special grade just that quiet? possibly both..

sukuna tensed up as he felt a presence behind him, swiftly turning around. a large, worm-like creature stared at him, its mouth opening. "CLEAV-" before sukuna's technique was released, a loud screech left the curse's mouth. it completely destroyed the building while the soundwaves pushed you and sukuna out.

sukuna grabbed you, shielding your body as you both landed on the ground. he looked towards the curse as anger fueled him. a sadistic grin soon appeared on his face. "oh, this'll be fun!" he exclaimed, lunging at the curse. he let out of a furry of punches, each punch filled with cursed energy. the special grade cried out as it became overwhelmed with the sudden attacks.

it went to scream again, but sukuna held its mouth shut, his grin widening. "DISMANTLE!" a large slash came down onto the special grade, cutting in completely it in half. sukuna landed on the ground as he dusted himself off. "you give this brat a run for their money if this was an annoying competition" he told the decaying curse, motioning to you before rubbing his now ringing ears.

☆☆☆

you awoke at jujutsu tech in the infirmary. you groaned in pain, sitting up. "shit. i was hoping that you had died" sukuna spoke as he scrolled through his phone. your head snapped to him. "what happened? is the special grade dead?" "i made quick work of that thing. my guess is that it made a sound at a frequency only dogs can hear. maybe it overloaded your brain or something."

you rolled your eyes. has he never heard that there's a time and place for everything, including his 'jokes?' "whatever man.." you spoke. silence filled the room. "..ya know, i didn't exactly expect you to save me" you said. sukuna looked up from his phone. "i was thinking that maybe you'd leave me there and tell the school that i had died or something."

he stood from his seat, now standing over you. you looked at him. sukuna began to pinch at your cheeks, making tears prick your eyes from the pain. "you're more of a dumbass than i thought" he told you as he let go. you rubbed your cheeks. "honestly, you're a pretty strong sorcerer, they wouldn't have believed me if i said something like that. plus, if i did leave you to die, who would i fuck with during class?"

you were in shock, to say the least. ryomen sukuna? being genuinely nice to you for once? "aww~ you softie!" you spoke, a grin on your face. sukuna tensed up, growling as he grabbed onto the collar of your uniform. "nobody's soft, brat! get off your high horse!" "sukuna the sweetheart!" "you got a fucking deathwish or something?!"

you only laughed in response. sukuna huffed as he released your collar. "i hate you so much.." he muttered, leaving the room. you giggled as you waved goodbye and sat back onto the bed.
