Hello, Goodbye and Sayonara (Naruto x JJK)

Wasuke tried to close his eyes, hoping for sleep to come. The hospital room was quiet now, the only sound the faint hum of machines and the memory of Yuuji's voice lingering in the air. His grandson had visited earlier, a fleeting warmth in an otherwise cold and sterile space.

But even that couldn't distract him from the gnawing pain deep inside—cancer cells eating away at what little strength he had left. Every breath felt like shards of glass dragging through his chest. Seventy years old. Goddamn it, he'd just turned seventy. Yet his body felt ancient, as if it had endured a hundred lifetimes of wear and tear. And he knew.

He could feel it in his bones, in the hollow ache that stretched through him—his time was close.

A bitter relief came with the thought. Soon, there would be no more pain, no more helplessness. No more being a burden to Yuuji, who already carried so much on his young shoulders. But the relief was laced with a deeper worry, one that clung to him like a shadow.

What would his wife and son say when he saw them in the afterlife?

Would they be angry, knowing he'd left Yuuji all alone in this cruel, unforgiving world?

Their only son, their precious grandson—abandoned to face it all without them.

He sighed, the sound barely more than a whisper. Maybe it didn't matter anymore. Maybe none of it mattered. His body felt heavier by the second, as if the weight of existence itself was finally dragging him under.

And then, it happened. Consciousness slipped through his fingers like sand. The world around him faded, swallowed by a darkness so complete it left no room for thought, for fear, or for regret.

Yuuji felt like he was in heaven, not trapped in some eerie domain expansion. It didn't matter where he was—this moment, this impossible reunion, was everything. His grandpa was here, alive and warm, just like he remembered.

After all those years of being alone, of feeling lost and hollow, Yuuji finally had him back. Without a second thought, he threw his arms around Wasuke, holding on so tightly it was as if letting go would shatter the fragile dream.

He buried his face into his grandfather's shoulder, tears spilling freely. "I missed you so much, Grandpa..."

"Alright, alright," Wasuke said gruffly, though his hand was gentle as it stroked Yuuji's hair. "Enough of that crying. Your snot's gonna ruin my shirt."

Yuuji choked out a laugh between sobs. "Sorry, Grandpa…"

Wasuke clicked his tongue but kept his hand on Yuuji's head. "Enough now. You're a big boy, Yuuji. Don't go making yourself a crybaby. Look ahead, not behind." His calloused fingers brushed Yuuji's cheek, the way they used to when he was just a kid, always scraping his knees or losing his favorite toys.

The ache in Yuuji's chest eased a little. He sniffled and nodded, wiping at his face as Wasuke gave a small, approving grunt.

They walked together, side by side, and found a seat near Gojo-sensei and Megumi. Yuuji couldn't help the warmth that spread through him as he watched them. Gojo-sensei, ever his usual self, had a soft smile on his face, holding Megumi close. The younger boy had fallen asleep, his head resting against Gojo's shoulder like it was the most natural thing in the world.

For the first time in a long time, Yuuji felt something unfamiliar but welcome blooming in his heart—joy. He wasn't alone anymore. Not here.

Not now.

Her breath felt like it was going to run out. Her lungs felt like they were being stabbed by thousands of needles. Her vision also started to blur.

"KEEP YOUR EYES OPEN, KUSHINA!" Minato shouted.

She kept trying to open her eyes. However, the drowsiness was so heavy, that she wanted go to sleep.

A short nap won't hurt anyone, dattebane?

She closed her eyelids to go to sleep, and the last thing she heard in her ears was the sound of Minato screaming her name before everything became silent and dark.

.

.

.

"Wait, why the fuck do they look familiar?" Toji muttered, his sharp eyes narrowing as he tilted his head slightly, scrutinizing the images in front of him.

"Because they're characters from Anime, you dumbass," Gojo shot back.

Naoya scoffed. "You watch cartoons? Seems like the great Gojo clan has hit rock bottom as you get older."

Toji smirked, leaning back with his arms crossed, clearly enjoying the jab at Gojo. "Yeah, looks like all that 'Strongest Sorcerer' crap only went so far, huh?"

Satoru's grin faltered for a split second, replaced by an almost imperceptible twitch of annoyance. Before he could retort, Geto, who had been sitting quietly, suddenly cut in.

"Shut your damn mouth," he growled, his voice low but sharp enough to slice through the air like a blade. His dark eyes flicked toward Naoya, narrowing dangerously. "No one wants to hear a nobody Zen'in spewing garbage."

The room went still.

Naoya's smirk faltered for just a second, his fingers clenching into fists at his side. Toji's lips twitched, somewhere between amusement and irritation, as his gaze darted between Geto and Naoya.

Meanwhile, Gojo turned his head slowly, raising an eyebrow at Geto. The sharp edge of humor in his eyes softened into something more curious, more cautious. He leaned back, crossing his arms as if settling into a show he hadn't quite expected.

The bitterness in Geto's tone wasn't unfamiliar, but this? This felt like a flash of the old Suguru—the one who used to stand shoulder-to-shoulder with him, cutting down enemies without hesitation. And for a second, Gojo almost forgot. Almost forgot the betrayal, the blood, the lives ruined.

But he didn't. He never could.

Still, he couldn't help the faint twist of amusement in his chest, his lips twitching upward. "Well, well," he drawled, his voice deceptively light. "Never thought I'd hear you stepping in to defend me. Nostalgic, isn't it?"

Geto didn't respond, his posture stiff and his eyes fixed firmly ahead, refusing to meet Gojo's.

.

.

.

Itadori Jin was feeling extremely nervous. He had been anticipating this moment for quite some time. Occasionally, he would check his watch and the pockets of his pants.

' Luckily, I remembered to bring it, otherwise I would be so embarrassed,' thought Jin as he took out a small red box from his pocket and placed it back in his pants pocket.

Today was the day, he had been waiting for.

After dating Hana for 2 years and having twin baby boys who were just 3 months old. He was going to propose to her and make her his wife. He had also arrived early at their agreed-upon meeting place to surprise Hana with this.

For the past two hours, he had been waiting in the park. Hana had still not appeared. The time on his watch showed 11:30 PM, close to midnight. There was nobody else in the park except for him, sitting alone on a park bench.

'It seems like she won't come today. Should I just go home now? Or should I wait here for a few more minutes?'

.

.

.

"Oh wow, Yuuji. He looks so much like you! Pink hair!" Gojo-sensei exclaimed, pointing at the cinema screen with a cheerful tone, as if trying to lighten the mood. But Yuuji only raised an eyebrow.

He knew his family well—there was no uncle (aside from Sukuna, who didn't count, because, well, admitting to having a ancient cursed spirit/serial killer uncle was a whole different issue) or any distant male cousin with the trademark pink hair that ran in the Itadori bloodline.

No, this was different. This wasn't some random relative. The man on the screen... it had to be his father. His real father. The one he had never met.

Itadori Jin.

And now, it all made sense. The weight behind his grandfather's gaze whenever he looked at him. The sadness Wasuke always seemed to carry. Yuuji looked like a near-perfect copy of the man on the screen.

"That's my dad, Sensei! Right, Grandp-..?" Yuuji's voice faltered as he turned to his grandfather. But the question hung in the air, unfinished. His grandfather's face—always so strong, so steady—was different now. Sadness etched into every line, a sorrow so raw that Yuuji felt his chest tighten just looking at him.

"Jin..." Wasuke whispered, his voice soft, trembling. There was love there, yes, but it was buried beneath layers of grief.

.

.

.

His thoughts were interrupted when his brown eyes caught sight of something suddenly shining brightly behind the bushes. The light quickly faded, but Jin's curiosity remained undiminished. He walked towards the source of the shining light, eager to satisfy his curiosity. As he approached the bushes, he caught a glimpse of what lay behind them.

The first words that escaped his mouth were,

" Gorgeous."

There, lying unconscious on the ground, was a woman with a stunningly beautiful face and long, red hair resembling a blooming rose. Her attire was unfamiliar to Jin, not something he had seen on an average woman.

.

.

.

"Ohhh, this is just like one of those romance drama moments! Love at first sight!" Gojo declared.

"This is Yuuji's dad, not some random meet-cute," Megumi deadpanned, his voice still a little thick from crying. "He wouldn't even exist if that happened, you idiot."

Gojo's heart did a tiny celebratory somersault. Megumi was talking again. Progress!

"Nu-uh, Megu-chan! In another universe, anything is possible," Gojo quipped, wagging a finger in mock reprimand like he was some all-knowing sage.

"Have you ever been in love, Sensei?" Yuuji asked, his tone pure and curious, the kind that could disarm anyone.

Gojo froze for a fraction of a second, his grin faltering just enough to be noticeable if you were paying attention. His gaze flicked ever so briefly to Geto, who was leaning casually against the wall a few feet away, pretending not to eavesdrop while failing miserably.

"Yesn't,"

"That's not even a real answer!" Megumi huffed, his brow furrowing in a way that made him look far too serious for his age.

"Yeah, Sensei, that's not a real word!" Yuuji chimed in, half-laughing.

"Sure it is! 'Yesn't' is totally a thing," Gojo shot back with a mischievous smirk. "Look it up—oh wait, you can't. Because I just invented it."

Megumi groaned, pinching the bridge of his nose, while Yuuji burst out laughing. Somewhere in the background, Geto let out an amused snort before quickly pretending he hadn't heard a thing.

.

.

.

It was only then that he realized the severity of her injuries when he saw her abdomen oozing fresh blood, almost the exact shade as her hair. Panic set in, and without hesitation, he quickly took off his jacket and used it to tie around her wound, temporarily stopping the bleeding. Swiftly, he picked her up and hurriedly carried her back to his house.

Upon arriving home, Jin burst through the door, startling Itadori Wasuke, who was still awake. Wasuke was so shocked that he nearly choked on the pill he was about to take before going to bed.

"What the fuck-?"

.

.

.

"Language, Itadori-san! There are children present!" Gojo scolded, though the wide grin on his face made it abundantly clear he wasn't serious.

"Hey! I'm turning 21!" Yuuji protested, puffing his cheeks like a disgruntled hamster.

"And I'm 28, which makes me ancient compared to you. Therefore, you're still a child, Yuuji-kun. And Megu-chan too!" Gojo declared with a teasing lilt, leaning back in his seat like he'd just made an unarguable point.

"Leave me out of this," Megumi muttered, his face halfway buried in his hoodie.

Wasuke, sitting nearby, rolled his eyes but couldn't help the small grin that tugged at his lips as he watched their antics.

Meanwhile, in the corner of the cinema, Geto sat with Mimiko and Nanako perched on either side of him, the twins clearly more interested in interrogating their father than watching the movie.

"Why'd that guy bring the woman to his house, Geto-sama? Why didn't he just take her to a hospital?" Mimiko asked, her tone genuinely puzzled.

"That normie man probably wants to steal her virginity and then sacrifice her to wild cursed spirits. Right, Geto-sama?" Nanako added with a disturbingly casual air, earning a soft chuckle from Geto.

"Uwaa, normie are so scary," Mimiko whispered, inching closer to him as if the idea had sent a chill down her spine.

Geto leaned back with a calm, almost lazy air, his hand gently brushing over their heads in a soothing motion. "No need to worry, sweetie. If any monkey even thinks of touching either of you without your permission, they'll get an up-close introduction to my finest cursed spirits. And trust me…" He smiled, sharp and cold as ice. "…it'll be a meeting they'll never forget."

.

.

.

" Dad, could you bring my medicine box?" pleaded Jin to his father.

Wasuke had a sense of deja vu. Suddenly, he remembered about 17 years ago when Jin, who was only 5 years old at the time, came home with tears streaming down his cheeks, carrying a fallen baby bird from its nest.

" Dad, could you help it?" his son pleaded, crying for the injured bird with a wounded wing.

" Dad."

" Dad."

"DAD, HURRY!"

A scream from his son snapped Wasuke back to reality. He immediately began searching for the medicine box that he kept in his room.

.

.

.

"Wait a minute, I just realized—that's not our old apartment. Since when did we have a house way out in the countryside?" Yuuji asked, his brow furrowed in confusion.

His memories were clear: he and his grandfather had always lived in the middle of a bustling city. It wasn't Tokyo, sure, but it definitely wasn't a two-story house in a quiet rural area like the one on the cinema screen.

"We used to have that house," Wasuke said, his voice steady but tinged with nostalgia. "I bought it back in the '70s as a birthday gift for your grandma's 23rd."

"Wow, really? I didn't know that, Grandpa! That's so cool!" Yuuji exclaimed, his eyes lighting up with genuine excitement. "But… why don't we live there anymore? It looks so nice."

"Bad memories," Wasuke replied simply, his face softening into something sad and faraway.

"…Oh," Yuuji murmured, the enthusiasm in his voice fading. The weight of his grandfather's tone told him everything he needed to know. Whatever had happened in that house, it wasn't something his grandfather wanted to relive.

Yuuji looked down at his hands, unsure what to say. There was so much about his grandparents' past that he didn't know, and this was clearly one of those things. For once, he chose not to press further, letting the silence settle between them.

Wasuke's gaze lingered on the screen, his expression unreadable. But after a moment, a faint, wistful smile touched his lips.

"It was a beautiful house," he said quietly, more to himself than anyone else.

.

.

.

With great caution, he carefully retrieved the medicine from underneath his son's bed, making sure not to disturb his two grandsons, Sukuna and Yuuji, who were still fast asleep on the nearby bed.

.

.

.

"HOLD UP, WHAT?!/ WHAT THE FUCK?! " Yuuji and Gojo shouted in unison, their voices echoing through the cinema as their eyes stayed glued to the screen.

Beside them, Megumi just sat there, mouth agape, too stunned to form a single word. Anime characters being real and somehow transported into the Jujutsu world? Sure, weird as hell, but still manageable. But finding out that Sukuna, the King of Curses himself, was Yuuji's baby twin? That was a whole new level of what the fuck.

"HA! Just as I thought!" Naoya sneered, his voice cutting through the stunned silence. "You're descendants of Sukuna! That's why you can control him! The Elders should've just executed you on the spo—UGH!!"

His rant was abruptly silenced as a sandal smacked him square in the face.

"Keep my grandson's name out of your filthy mouth," Wasuke snapped, his voice laced with fury as he stood with another sandal in hand, ready to strike again. "Say one more word about Yuuji, and you'll be eating this one next!"

Naoya sputtered, too stunned to respond for a moment. His pride took a hit, being publicly humiliated by an old man who didn't even have Jujutsu, one who—he bitterly noted—smelled faintly like grave dirt.

But when Naoya tried to get up, he realized something was wrong. He couldn't move. It was like he'd been glued to his seat, completely immobilized.

"What the fuck is this?! " he growled, struggling against the invisible force pinning him down.

Wasuke just smirked and casually dusted off his hands. "That's what you get for running your mouth. Learn some damn manners."

Naoya glared, but the others were too busy trying to process what they'd just seen to pay him much attention. Even Gojo looked rattled.

"Yuuji," he said, running a hand through his hair. "You've got some serious explaining to do."

"I swear I don't even know it, Sensei!"

.

.

.

Wasuke closed the door to his son's room softly before rushing downstairs to the first floor. In the living room, he saw his son who had already undressed the red-headed woman and was carefully cleaning her body with a wet cloth dipped in water to prevent any infections.

"Oh, thanks, Dad. Don't worry, I'll take it from here," Jin said as he took the box of medicine from Wasuke's hand and began treating the woman's wounds with the supplies in the box.

He observed his focused son attentively tending to the woman's injuries. Her body was covered in cuts and the most severe one was on her stomach.

He's beginning to doubt if that woman is gonna life to see the tomorrow morning.

.

.

.

"Wow, Dad can heal?!" Yuuji asked, his voice brimming with excitement. The enthusiasm made Wasuke chuckle softly at his grandson's lively energy.

"You bet, kid! He even went to college as the youngest student to become a goddamn doctor!" Wasuke said, a hint of pride in his tone. "But in the end, he decided to drop out and become an office worker instead."

"That's kinda a waste of talent... No offense," Megumi chimed in, his expression a mix of curiosity and blunt honesty.

Wasuke waved it off with a grin. "A, it's fine. Besides, I forgive him. He gave me the cutest grandson ever, after all." He reached over, rubbing Yuuji's head and playfully ruffling his hair.

.

.

.

"Oh, dad, you're still awake? Remember the doctor's advice to sleep on time and not stay up too late," Jin said.

" Bah, forget about the doctor's advice! I'm more experienced than any doctor! I know my physical limits very well. Besides, how can I sleep when I see you coming in like this? Who is that woman? Where's your supposed girlfriend? Weren't you supposed to go on a date with her?"

"Hana didn't come to the park tonight. Maybe she's busy-"

"YOU KNOW WHAT, FORGET IT! Your " Cute" girlfriend only came here to drop off her two kids! And just disappearing god knows fucking where! Do you still think she'll come on a date after abandoning Yuuji and Sukuna here?! I'm sure she's out partying at some nightclub, with shady men, offering herself to others behind your fucking back,"

" ENOUGH, FATHER!"

"...."

.

.

.

Yuuji clenched his fists, his whole body tense as he listened to his father yelling at his grandfather. He hated it. His grandfather wasn't wrong.

In his eyes, Itadori Jin had so many choices. He could've married a kind Japanese woman, or even a good-hearted man and maybe adopted a child. But instead, he fell for her. For Kenjaku's trickery. That woman—no, that thing.

His jaw tightened. He would never accept it. Never. That thing wasn't his mother. It never was and never would be.

.

.

.

"I understand you've never liked Hana! But she's the one who filled the void in my heart after Rui passed away. Hana is also the one who gave you your grandchildren, Yuuji and Sukuna! I know she has her flaws, but I love her!"

Wasuke remained silent and walked towards his bedroom. Before closing the door, he said to his son, " Just so you know, my instincts are always right about someone's true nature and character. So don't come running to me, crying and complaining, when Hana's true colors come out and break your heart."

Jin could only watch as his father's bedroom door slammed shut loudly. His evening took a turn for the worse. Feeling defeated, he found himself sitting on the floor in the living room, impacted by the hurtful words his father had just uttered.

It always seemed as though luck was not on his side when it came to matters of the Love.

.

.

.

"Wow, that's some big tea," Gojo said with zero restraint, leaning back like he was settling in for a show. "Is your son, like… I don't know....maybe actually colorblind? Because having that kind of girlfriend as his dream wife? That's a parade of red flags marching through a dumpster fire. Even I wouldn't touch that mess."

"Gojo-sensei!" Megumi hissed, glaring at him.

"It's fine, kid," Wasuke said with a tired chuckle. "I get it. My son… unfortunately, he's as hard-headed as I am. He always sees his girlfriends through rose-tinted glasses. To him, they're never in the wrong, and he'll always take their side. That's his biggest flaw—and his deepest regret."

"So, basically," Geto chimed in, a sly smirk spreading across his face, "you're saying your son's just a people pleaser with terrible taste in emotionally unstable women. Good to know Monkeys are still attracted to Garbage."

Yuuji didn't even hesitate. He shot Geto a sharp glare and flipped him off. "Say that again, I. dare. you."

.

.

.

Just like his late mother who passed away when he was 10 years old, his son was too kind and naive. Even after his mother's death, he still held onto her teachings, as she was a nurse during her lifetime.

Jin inherited his mother's talent for healing others, as well as her innate goodness and naivety. When they were teenagers, Wasuke, who was close friends with his wife, would often witness her being teased and pranked by her older classmates at school.

Sometimes, she wouldn't even realize that she was being pranked by her seniors.

.

.

.

"Is Grandma really that oblivious to people bullying her? Like, I'd definitely know if someone was bullying me instead of asking me for help," Yuuji said with a confidence smile.

Megumi and Wasuke exchanged a glance, both putting on straight faces at his answer.

" Look who's talking. You're just as the same,"

"Huh? You say something, Megumi?"

"Nothing, just watch the screen,"

.

.

.

"Oh, darling. If only you were still alive. You would know what to do for our child," he murmured, kissing the wedding ring he still wears from his late wife.

Wasuke hopes and prays to a higher power for guidance and protection for his son and grandchildren from any potential harm.

He also hopes his son realizes and finds a better partner than the one he has now.

.

.

.

Yuuji's gaze shifted to his grandfather, taking in the sorrow etched across his face. The old man's expression was heavy, his eyes glistening with tears that silently slipped from the corners. It didn't take much for Yuuji to guess what was going through his mind. His grandfather probably felt responsible—like some part of his dad's death was on him.

It all led back to Kenjaku that thing.

Yuuji understood his grandfather better than most. People often mistook the old man's stern reprimands as harshness, but Yuuji knew better. Beneath that gruff exterior was someone who only wanted to protect and guide, even if his methods seemed heavy-handed.

Maybe that's why his grandfather was so overprotective. He always warned Yuuji not to rush into love, to truly know someone before making serious commitments. It wasn't just advice—it was a shield forged from past regrets and deep wounds. His grandfather had already lost two of the people he loved most.

And now, Yuuji realized, his grandfather was probably terrified of losing him too. Afraid that Yuuji might leave him behind, just like the others.

Without a word, Yuuji did what any kind grandson would do in that moment. Wrapping his arms around the old man, Yuuji held him close, offering what little comfort he could.

.

.

.

" Did you kill him, yet?"

"No, my deepest apologies, Kenjaku-sama," replied the black-robed figure. "The person you wanted me to target was not present."

Kenjaku seemed to pause for a moment, then took a seat in one of the chairs, crossing his legs. "Alright then. Go back to your original position. I'll handle this problem myself in the future."

"Understood, Kenjaku-sama," responded the figure.

.

.

.

Gojo squinted at the screen, trying to make sense of the woman displayed. She had a scar on her forehead and a pair of eyes that, strangely enough, reminded him a little of Yuuji. No doubt about it—this had to be Hana, the one Itadori Jin and Wasuke had been talking about. She had an air about her, like an unknown curse user, or maybe someone just really damn good at hiding. Either way, Gojo was sure he'd never crossed paths with her before. If—no, when—he got back home, he'd definitely need to run a deep background check on her.

Something didn't sit right.

But what really threw him wasn't Hana—it was the way his students reacted to seeing her on the screen. The second her face appeared, their expressions darkened. They looked like wild animals, eyes sharp and burning with hate, ready to tear her apart. It wasn't just anger—it was rage. Pure, seething rage.

Gojo's stomach tightened. Shit. This woman must've done something, something bad enough to leave scars on them—especially Megumi. And just like that, he finally had a clue about who had hurt his kids while he was away.

"Damn," Toji drawled, breaking the tension with a cocky smirk as he leaned back in his chair. "She's got some nice big racks, though. Gotta hand it to her. Those seem legit as fuck."

The room fell into stunned silence.

Gojo, Megumi, Yuuji, and even Geto all turned their heads in unison, fixing Toji with synchronized glares and scowls.

The cinema screen faded to black, and the dim ceiling lights flickered back on, casting an eerie glow over the room. Then, just like before, the voice of an unknown speaker echoed through the theater, smooth and calm yet unnervingly detached, as if it came from everywhere and nowhere at once.

"Chapter One has concluded. Thank you for your cooperation. As a gesture of goodwill, we will grant you a break outside the cinema, where you may sleep, rest, and eat before the next chapter begins."

The words lingered in the air, carrying an odd mix of warmth and something… unsettling. Before anyone could respond, a large gate materialized at the far end of the theater.

With a groan of ancient wood and unseen mechanisms, it slowly creaked open on its own, revealing an inviting but unknown expanse beyond.

Even Naoya, who had been quietly fuming in his seat, stood up with a reluctant scowl. Hunger gnawed at everyone, leaving little choice but to comply. One by one, they began shuffling toward the gate.

Yuuji hesitated, lingering near the back. Something about the voice intrigued him, its calmness both soothing and unnerving. Swallowing hard, he raised his hand slightly, his voice uncertain. "Erm… can I ask a question?"

"Ask, My Child," the voice responded, smooth as silk and oddly comforting, like the whisper of a parent soothing their child after a nightmare.

Yuuji took a breath, his tone cautious. "How long are we… going to be here? I mean, stuck in this place?"

A pause. It wasn't long, but it was enough to send a ripple of tension through the room. Then the voice returned, steady and composed.

"We do not know how long you will remain. But we can promise you two things: when you return, time in your world will not have passed… and you will go home."

Yuuji blinked, then exhaled a breath he hadn't realized he'd been holding. Relief washed over him, and he managed a small, grateful smile. "Thank goodness. Thanks for answering."

"You are welcome, my child," the voice replied, its tone almost… kind. "Now, please enjoy your break. You will be summoned when the next chapter is ready to begin."

The words faded, leaving the room in silence once more. Yuuji glanced at the gate, its ominous presence somehow less threatening now, and joined the others as they stepped into the unknown.
