The Sixth Transmigration

by sasuwux

Summary:

In her new life, Amelia awakens as Ryomen Sukuna. The world fears her, misreads her intent, and underestimates the mind behind the myth. But Amelia has lived many lives before this one. Now as Sukuna, she navigates a landscape of curses, shifting loyalties, and enemies who don’t yet realize she’s rewriting the game. With allies uncertain and tradition crumbling beneath her, she crafts a plan that bends fate to her will.

Nobody warned Satoru Gojo, that the monster he was born to hate through stories would become the soulmate he couldn’t live without. That the Queen of Curses would wield not just power, but poetry, and a control so intoxicating it made him ache. He came to fight her. He stayed to worship her.

***

A curated collection of flashbacks from Amelia’s sixth transmigration—this time as Ryomen Sukuna, the infamous Queen of Curses. In her fifth life, she was the insufferable Dazai Osamu, tormenting her soulmate Nakahara Chuuya. Now? She’s stuck with Satoru Gojo as her soulmate—an endlessly flirtatious, masochistic brat who clings to her like a curse she can’t exorcise.

Chapter 1

Hey there!

If you’ve stumbled upon this collection without reading my main story The Seventh Transmigration, here’s a quick rundown to help you make sense of the chaos (and maybe tempt you into diving deeper).

This work is a companion piece to The Seventh Transmigration, which takes place in the Hazbin Hotel universe. In that story, Amelia Montgomery has transmigrated into Alastor, and throughout the chapters, I sprinkle in flashbacks from her previous lives to build parallels and deepen emotional context.

This archive specifically gathers all the flashbacks from her sixth transmigration—when she transmigrated as Ryomen Sukuna in the Jujutsu Kaisen universe. Her soulmate in this incarnation? None other than Satoru Gojo, the walking blindfolded headache. Yes, it’s karma.

- These flashbacks are shorter than my usual chapters—they’re meant to supplement the main story, not replace it.

- The flashbacks are presented out of chronological order. Sometimes Sukuna and Gojo are lovers, sometimes enemies, sometimes both in the same breath.

- A CHARACTER CHART is included to help you track Amelia’s transmigrations, abilities, and relationships across lifetimes.

When Amelia transmigrates, she becomes the character—not just a soul riding shotgun. Sukuna retains 'her' canon personality, but with layered memories from Amelia and her past lives. So it’s not “Amelia pretending to be Sukuna,” it’s “Sukuna with echoes of Amelia.” Still AU, still out-of-character in some ways (because, you know, soulmates), but internally consistent within this universe.

Also: Sukuna can communicate with her past selves. They reside in her mind. They talk. A lot. Sometimes helpfully, sometimes sassily. But I don’t add that to my flashbacks, only to the main story… but it is something you should know.

And yes, she inherits powers from previous lives depending on the circumstances. In this life, she’s ridiculously OP—wielding Dazai’s nullification ability and Sasuke’s Sharingan. (As Dazai, she had no powers because nullification cancels everything, so she was just a very chaotic human.)

- If you’re here just for a Sukuna SI, I got you.

- Flashbacks jump around. No linear timeline.

- If you enjoy this, maybe you’ll give The Seventh Transmigration a try. That’s just my wishful thinking, of course :p

This collection will be updated whenever a new flashback appears in the main story, The Seventh Transmigration. That means updates may become inconsistent after the fourth flashback, depending on how the chapters unfold.

I’ll be adjusting the tags as the story develops. Right now, the scope is still small—limited characters, limited situations—so expect the tags to evolve as more dynamics and layers are revealed.

Happy reading!

FLASHBACK ONE

“I can’t believe we actually sat through that trash.”

Satoru Gojo muttered, his expression twisted in exaggerated disgust. He leaned back on the bench, his long legs stretched out in front of him as he dramatically sighed.

Yuji had practically begged Nobara and Megumi to join him at the cinema to watch the latest installment of the Human Earthworm franchise—Human Earthworm 4. The only reason they’d agreed was on the condition that Gojo would pay for both the tickets and the meal afterward. That, of course, had prompted Yuji to plead with Satoru and Sukuna to tag along. Like the indulgent teacher he was, Satoru had agreed, though his motives weren’t entirely selfless. It was practically a date with Sukuna, after all—albeit with the kids in tow.

He glanced at her now, a small smile tugging at his lips. She was in her smaller form, standing at 5’8 instead of her usual imposing seven feet. He almost cooed at the thought. While he adored her towering presence, there was something undeniably satisfying about being the one to wrap her in his arms when she shifted down to blend in with humans.

After the movie, the kids had gone to eat at a nearby café, leaving the two of them sitting on a bench in the park across the street. The faint glow of the café lights reflected in Sukuna’s pink hair as she leaned back, her expression calm and unreadable.

“I quite liked it” Sukuna said with a shrug, her tone casual “The effects were accurate when it came to the body parts.”

Satoru turned to her, his pout deepening “Of course, that’s what you focused on. I bet you felt right at home.”

Sukuna arched an eyebrow, amusement flickering in her eyes “You do realize you’ve killed people and curses in far more gruesome ways than anything shown in that fictional movie, right?”

Satoru flicked his tongue at her in mock defiance “That’s not the point. The point is—”

“There is no point, brat” Sukuna cut him off, her tone sharp but playful “Stop being an idiot. We didn’t even have to go inside the theater. You could’ve just paid for their tickets and food, and we could’ve gone somewhere else.”

“But Yuji said he wanted us to be there and share the experience” Satoru whined, shifting closer to her on the bench. He wrapped an arm around her shoulders, pulling her against his chest “How could I say no? Be a good girlfriend and comfort me.”

“Die” Sukuna replied flatly, her voice muffled against his jacket. She sighed but adjusted her position, leaning into him more comfortably. Now, they sat side by side, her head resting against his shoulder as his arm remained draped around her.

“I don’t know how he does it” Satoru mused, his tone light but tinged with exasperation “One moment, he’s asking me about how my Infinity works during training, and the next, he’s dragging us to watch that garbage. Kids these days” he chuckled, glancing down at her “The lesson earlier got pretty existential, though. He questioned whether my Infinity truly covers everything.”

Sukuna hummed softly, her gaze fixed on the distant lights of the café. She didn’t respond immediately, prompting Satoru to continue.

“You know” he said, his tone darkening slightly “I can bring the concept of Infinity to reality, but it isn’t actually true. As we talked about earlier, there’s still that nothingness—that void I could never get close to. If I did, I would be screwed” he chuckled, though there was a faint edge to it “Can you imagine? Being overwhelmed by nothing?”

“A terrifying thought” Sukuna replied, her voice calm but laced with understanding.

“Indeed” Satoru agreed, his tone softening “It’s a good thing you and I will never find out.”

This time, Sukuna turned to look at him, her crimson eyes locking with his piercing blue ones “Oh? And how are you so sure?” she asked, her curiosity evident.

“Because I’m protected by my Infinity” he said with a shrug, his smirk returning “My Six Eyes warns me to never mess with it and Infinity won’t let me get close to it. And I’ll make sure my Infinity protects you too.”

“That doesn’t make sense” Sukuna snorted, shaking her head “Besides, we won’t always be together.”

“Of course, it makes sense. That’s why it’s called Infinity” he replied playfully “It doesn’t matter if you’re on the other side of the planet. I’ll stretch it until it finds you—if I can’t teleport to your side, that is.”

Sukuna shook her head again, her expression softening slightly “You don’t have that level of power, and…” she hesitated, her voice dropping “And you’ll die before me.”

Satoru’s gaze grew more intense, his blue eyes unwavering as he studied her. A small, genuine smile curved his lips “Then I’ll just curse you” he said simply “And I know it’ll work because… love, while being the most twisted curse, is also the most powerful one.”

His next words made her tense slightly “So, you’ll be fine… even when I’m gone.”

Sukuna didn’t respond immediately. Instead, she studied his face, her expression unreadable. After a moment, she rested her head back against his chest, closing her eyes.

“And since I’m so powerful” Satoru added, his voice soft but teasing “Even when you go to your next life… my curse will go with you.”

Those words earned him a reaction. Sukuna’s arms moved, wrapping around his chest in a rare display of affection. Satoru chuckled, the sound warm and genuine as he tightened his hold on her. Moments like these, when Sukuna let her guard down, were the ones he cherished most.

Notes:

The concept of Nothing/Void plays a significant role in the main story. True to his word, Satoru cursed Sukuna, it protected her even beyond death. When she transmigrated and awakened as Alastor, his curse energy shielded her from the effects of the Void she had to pass through.

Since this is an AU, there are moments where even Gojo’s techniques behave differently. The multiverse in this story is fluid, realities interline, bleed into one another, and occasionally rewrite their own rules. That’s one of the reasons Sukuna retains powers from her previous lives.

Flashback from CHAPTER THIRTY FIVE of the main story.

FLASHBACK TWO

The room stank of iron, gutted lighting buzzing overhead where intestines dangled from bent copper piping. The walls were smeared in blood—some of it sprayed, some of it hand-drawn into glyphs that pulsed faintly with energy and had seen only drawn by Sukuna before. Satoru Gojo stood in the carnage, blinking at the mess with casual awe.

And just ahead, Sukuna Ryomen stood in her shorter form, drenched head-to-toe in crimson, not a strand of her pink hair untouched. The only thing clean from her face was her mouth—which, in Gojo’s opinion, was both reassuring and statistically miraculous. She did not eat anyone, props.

“Sukuna! It’s so good to see you again” he crowed theatrically, arms flung wide as if waiting for a reunion hug he would never receive “While I was trapped in that cold little box, do you know what I thought of? The red of your eyes, your beautiful pink hair, your two massive—AUGH!”

Her fist drove into his stomach with precision, bypassing his infinity. The air evacuated his lungs with a loud gasp as he doubled over, knees nearly buckling.

“Shut up, you pervert” Sukuna drawled, glaring down at him as he wheezed with laughter “It’s been a week. One week, you fucking idiot. I told you to be careful. I warned you. And you—like the goddamn compulsive arrogant idiot that you are—ran headfirst into a trap set by Kenjaku.”

“Look, I was busy protecting civilians” Gojo argued, voice slightly higher-pitched than normal thanks to the hit. He rubbed his aching ribs and grinned weakly “Unlike you, oh Mighty Curse Queen, who took a week to pull me out. Which means—let me guess—Kenjaku slipped past you too. So who’s really the stupid one?”

“You’re comparing rescue response times like this is a quiz” Sukuna muttered, rubbing her temple.

Gojo flashed a thumbs-up as he gestured around with dramatic flair “Besides, I forgive you. You’re hot. And humble sorcerer that I am, I’m willing to look past your flaws out of love.”

“I’m going to rip your tongue out and eat it.”

Gojo pursed his lips and tilted his head “I don't think you realize what kind of effect that has on me when you say it.”

“You’re a fucking child.”

“An emotionally secure child” he corrected with a smug smile.

His eyes finally scanned the rest of the scene—blood pooled under his boots, glistening intestines swinging overhead like party streamers “I didn’t mention it right away because I was soaking in the view” he said casually “But I feel like I missed something major, since the room is definitely decorated in viscera” he pointed toward the ceiling “I recognize this place we are in. Are those the higher-ups?”

“Yeah” Sukuna replied smoothly, not bothering to sugarcoat it “I killed all of them. You’re welcome, by the way. They voted to classify you as a traitor permanently. Ordered you never to be unsealed. Planned to execute your old principal, too. And Yuji—was going to be next.”

She looked back at him with a feral smile, red eyes gleaming “Do you think I overreacted?”

Satoru Gojo stared at her, motionless beneath the hum of cursed silence. Blood still coated the walls in violent brushstrokes, soaked into the tatami beneath his boots, yet his gaze was fixed solely on her—the woman standing at the center of it all, drenched in red, perfectly still. Once, long ago, he’d thought this moment might belong to him. That when the time came to purge the rot of the jujutsu higher-ups, to take out the centuries-old corruption that ground down young sorcerers like meat, it would be his burden to bear. To destroy so the next generation could rebuild without the weight of their predecessors’ sins. And yet… Sukuna had done it. Decisively. Mercilessly.

And somehow, that made him fall for her just a little bit more.

He’d hated her, once—almost viscerally. Back when she was still thought to be a man. Back when he truly believed she’d consumed Yuji in cold blood. He’d tried to kill her. Lost. Badly. And learned it hadn’t been a fight at all. Sukuna had played him—crafted a scenario where the higher-ups believed Yuji dead, sparing the boy from their assassination order.

He hadn’t stood a chance. Not in battle. Not emotionally.

“Your response was entirely appropriate” Satoru said at last, his voice low and dazed, the words almost reverent.

Sukuna narrowed her eyes, catching the softened gleam behind his words “See, and that’s why I’m the smarter one” she said, striding toward him with deliberate grace “It was a brilliant idea to keep my body’s true state hidden—let those bastards believe I was still tethered to Itadori. Less suspicion. Fewer chains” her grin widened as she reached him, claws slipping into his hair and yanking his head down until their eyes were level. Predictably, his dazed expression twisted into one of amused pleasure, like he relished the pain her grip triggered. Typical masochist.

“And you” she drawled, red eyes gleaming “Are the dog that obeys my commands.”

“How could I refuse the Queen?” he murmured, gaze darkening with affection and something heavier—need, reverence, maybe both. The air between them buzzed with tension, thick and heady. He leaned closer, intent on shrinking what little space remained—

Until the door rattled.

“Uh, Sukuna?” came Yuji’s muffled voice, half-nervous, half-annoyed “Are you done? Did you free Gojo-sensei? You said it would be quick and it's been like… thirty minutes?”

Sukuna’s expression shifted instantly. She pushed Satoru away with a quiet huff and turned toward the door “I did free him, you little brat. I’m just catching him up” she growled, clearly annoyed “Don’t get impatient.”

“Damn it, Yuji…” Satoru muttered under his breath, eyes still trained on her as if the moment might resurrect itself.

A pause.

Then Yuji again, voice quieter “Yeah... I bet that’s what you two are doing…”

Sukuna narrowed her eyes “What was that?”

“Nothing!” Yuji chirped instantly “I’ll just head to training with the others now. Bye-bye!”

The other side of the door echoed with retreating footsteps.

Sukuna rolled her eyes and turned to Gojo, arms crossing over her stained chest “Thirty minutes” she echoed, tapping her claw idly against her elbow “The unsealing takes seconds.”

Gojo tilted his head, smiling with lazy admiration “You were having fun.”

“I was” she said with a shrug “I really enjoy taking my time when I’m only using my hands.”

Gojo blinked.

Once.

Twice.

And then cursed internally ‘Yuji, you bastard… why did you have to interrupt us now?’

Notes:

Number one thing to know about all her soulmates... Gojo is the horniest one of all:p
