I hope you enjoy diving into Arisa’s story.
Arisa Kurobane never believed in fate. She believed in anime marathons, late-night ramen, and the way stories made her heart race. Jujutsu Kaisen was one of those stories — a dark, thrilling escape from the dull pace of her real world.
But tonight, something shifted.
She remembered hitting play on her laptop, Yuji charging forward with Megumi at his side. Then… nothing. A tug in her chest, a dizzying pull, and when her eyes snapped open, she wasn’t staring at her bedroom ceiling.
She was lying on cold pavement. Neon signs buzzed overhead. The air was thick, heavy with a pressure that made her skin crawl. She sat up fast, panic tightening her throat.
Shibuya. This looks like Shibuya.
Her phone buzzed in her pocket. Relieved, she grabbed it — only to freeze. The wallpaper was different. The apps were the same, but the contacts weren’t hers.
At the top of the notifications was a group chat:
“Jujutsu High 🖤🔥”
Her stomach flipped. She knew that name.
Group Chat — Jujutsu High 🖤🔥
Yuji
Yo!! Who’s the new number Gojo-sensei added?? 👀
Nobara
Probably another idiot.
Arisa
Wait..This can’t be real
Yuji
LOL what can’t be real?
Nobara
Oh great, she’s already weird.
Arisa’s pulse hammered. These names. This chat. No way.
Yuji
Haha, don’t worry! We don’t bite. Well… except Nobara.
Nobara
Watch it, Itadori.
Arisa
Arisa. Arisa Kurobane.
Yuji
Nice to meet you, Arisa!! Welcome to Jujutsu High 🔥
Nobara
Ugh. Another newbie.
Megumi
Do you have cursed energy?
She lifted her hand without thinking. A faint shimmer — black sparks, like static — crackled over her fingers. Her breath caught. She felt it, thrumming through her veins like a second heartbeat.
Yuji
Awesome! Then you’ll fit right in.
Nobara
If she doesn’t die first.
Nobara
WHAT?? I’m just saying.
Arisa lowered her phone, staring at her hands. In her old world, she was nobody special — just another girl with exams, dreams, and too much time on the internet.
But here… her body wasn’t the same. It had power. And power in this world came with a price.
The city around her seemed alive with shadows. A flicker in the alley. A shiver in the neon glow. She swallowed hard. She knew what that meant.
Curses.
Group Chat — Jujutsu High 🖤🔥
Yuji
Don’t freak out, okay?
Megumi
We’ll meet you soon. Gojo insisted you join us.
Nobara
He’s probably laughing somewhere, dropping another newbie into our laps.
Yuji
Don’t worry! We’ll protect you. That’s what senpais are for 😎
She hesitated, then typed quickly:
Arisa
Um… one question. This might sound dumb
Nobara
All your questions will sound dumb.
Arisa
Where am I supposed to go?
Megumi
Tokyo Jujutsu High. Send me your location.
She glanced around at the bustling street signs. Shibuya. Her heart squeezed. She knew what happened here. She’d watched it play out on screen.
But now it’s real. Now I’m inside it.
As she typed her location, a wave of unease passed through her chest. She froze.
It wasn’t hers.
It wasn’t fear. It wasn’t hunger. It was something deeper — ancient and cruel — stirring for just a second in the pit of her stomach.
Yuji’s contact icon flickered green in the chat. He’d gone silent.
Yuji
Weird. For a second, it felt like Sukuna twitched inside me.
Nobara
Ew. Don’t say it like that
Megumi
Maybe he sensed something.
Arisa
(typing, then deleting)
Her throat went dry.
No. Sukuna couldn’t know. Not yet.
Arisa hugged her phone to her chest. She could still feel it — that faint echo, like a monster shifting in its sleep.
She’d wanted to be part of this world once, in the safe distance of fiction. But standing here, cursed energy crackling at her fingertips, the King of Curses stirring somewhere in Yuji’s body…
She realized she wasn’t a spectator anymore. She was a thread tangled in the fabric of this world.
And if Sukuna ever noticed her, if his eyes ever turned her way—
She might not survive it.
