Yandere!Geto X Isekai'd!Reader Drabble
lwk geto is kinda ooc with this one i think but its ok i have a better one up my sleeve its ok i swear (its not ok) lol this is also a separate one from my other yandere!geto x isekai'd!reader and lowkey i wanted to use you for everything but like i swapped it out so now it sounds eugh
Picture this: Yandere!Geto’s still a kid, way before Jujutsu Tech is even on his radar, and that’s when he meets you—a stranger from someplace else entirely. Honestly, you just popped into his world like you’d fallen straight out of the sky. Only, you’re not just lost or confused. You'd spot him, and your eyes would light up. Every. Single. Time. You'd cling to him, and you wouldn't ever let go. Everyone else might think it’s weird, but you’re different. See, in your last life—wherever you were from—he meant something to you. A lot. Maybe you obsessed over him. Maybe you memorized every little detail about his story. Either way, you hang onto him for dear life, like you’re terrified he’ll vanish if you blink.
Geto’s younger self isn’t quite sure what to make of it at first. You say wild stuff sometimes—talking about things nobody else would get, telling him he's special, even when he hasn’t done anything remarkable yet. But pretty soon, he just accepts it. If someone like you thinks he matters, maybe there’s truth to it. So, by the time the two of you march through the doors at Jujutsu Tech for the first time, you’re a team. And that’s where everything shifts.
Yandere!Geto notices Satoru, sure. Who wouldn’t? But honestly, Geto barely pays him a second thought. Why would he chase after someone else when you’re always right there? You look at him like he hangs the stars. And, honestly, that obsession goes both ways. He starts to act like you’re the only person who makes the world interesting. Everyone else becomes background noise.
So when people later ask how he never really befriended Satoru, Geto just shrugs. He doesn’t need another friend. He’s already got someone who knows him better than anyone—who won’t leave, no matter what. And in Geto’s mind, that’s more than enough.
------------------------------------
Yandere!Geto’s obsession really kicked in the day you got hurt during the Star Plasma Vessel mission. He couldn’t handle it; it was like watching a bird with a broken wing—his “poor little bird,” as he called you. From that moment, he threw himself into Reverse Cursed Technique, just to make sure he’d always be able to patch you up if anything went wrong. Defecting never crossed his mind seriously after that. Sure, he had his doubts and frustrations, but every time he saw you happy, the idea of causing you pain just seemed impossible. The world could fall apart, but making you cry? Never, if he could help it.
Well—at least, that's what he told himself for a while. Years passed. Something shifted. He noticed how your eyes always shimmered before tears spilled over, the way your nose crinkled, and your voice got all wobbly. One day, teasing you just a bit too much, he realized he almost liked it. Seeing you cry awakened something dark and strange in him. But Yandere!Geto wouldn’t admit it, not even to himself. He just kept finding little ways to coax those tears out, brushing it off as harmless fun, while feeling oddly pleased whenever you sniffled and glared at him. Not that you could help it—sometimes, you’d tear up over practically anything; he just had to poke a little.
You, though? You were still processing the whole being-isekai’d thing. Winding up here, in this world, with Geto attaching himself to your side like a persistent shadow, hadn’t been part of any plan. But you’d started to notice things were… better than canon, if you had to put it in anime terms. Geto hadn’t defected. He was way stronger than you remembered from the story, and—was he actually in love with you? You were starting to suspect you’d lucked out. Except, you missed the crucial detail. The Geto you knew from fiction didn't keep entire boards filled with contingency plans labeled “what if [Your Name]…” scribbled everywhere. Real-life Geto did. He’d catch himself plotting ten moves ahead, all centered on you. He just couldn't help it.
Yandere!Geto’s affection showed in all sorts of strange ways. He even tried making his curses look less creepy, just so he could give you one as a present. You found the gesture endearing and a little weird, not realizing he programmed it to quietly keep you safe, alerting him the moment things felt off. He couldn’t turn his curses into his eyes the way Mei Mei did with those crows, but he figured out a workaround. Guardian, ornament, or spy—call it what you want, but it was for you.
Isekai'd!Reader had their own quirks, too. Geto had a habit of going out with his friends, and there was this one café where the waitress seemed a little too interested for your liking. Jealousy flared in your chest whenever she hovered a little too close. Of course, you didn’t know that Yandere!Geto was already three steps ahead of you—he always turned her down, sometimes a little too bluntly. One time, to really drive the point home, he handed her a stack of bills and told her he wanted his girlfriend to get a little jealous. She laughed it off, playing along, but you only caught the part where she smiled at him. Your stupid eyes watered again, and Geto, seeing that, dropped everything to comfort you with a weird sort of pride.
Crying over a waitress? It made you feel ridiculous. You tried to hide your flaming cheeks while Yandere!Geto quietly savored the whole scene. He crooned soft reassurances until you started laughing at yourself. Maybe you weren’t actually that petty, and your eyes just had a mind of their own.
Eventually, though, the nostalgia faded. That soft ache in your chest—the longing to go back to where you’d come from—it just... wasn’t there anymore. After all this time with Yandere!Geto, after all the little routines and inside jokes, living with someone who obsessed over you in a caring, sometimes terrifying way, you realized there was nothing to “go back” to. This was home, and you didn’t really want to leave. The world you left behind might have existed once, but the person you were now only fit with Yandere!Geto by your side—clingy curses, secret plans, jealous tears, and all.
