Denji x M!Reader
content: Denji x male reader. You (y/n) are a devil whose mission is to steal Chainsaw Man's heart. However, you unexpectedly encounter Denji under surprising circumstances that change your plans.
note: Are we fw the new layout?? Everyone quickly say yes before my feelings get hurt. Anyway, I'm kinda in the mood to write Denji recently for some reason, maybe it's because of the movie. Finally figured out how to do the gradient, and tell me why it's such a genuine pain. Could this have been gender neutral instead? Yeah, but I do what I want.
It should’ve been simple. Y/n had been sent to kill Denji—to take his heart. Y/n was a devil. One who knew how to stay hidden.
To everyone else, they were just another student. A transfer, nothing special. There was always an excuse ready—my family moves a lot, my dad’s job, I had trouble at my last school. Lies came easily when you’d been repeating them long enough. No one questioned it. No one looked twice.
The truth was simpler. Y/n didn’t have a family. Never did. They were just a weapon—passed from place to place, mission to mission.
And now?
Chainsaw Man’s heart was the target.
The instructions had been minimal. A vague description, barely enough to go off. No location. No routine. Just a face—and even that wasn’t detailed. It should’ve been frustrating.
But y/n was used to working with less.
Denji was out walking.
Which—yeah, kinda weird.
Usually, he’d be crashing at home, mooching food, or doing literally anything that didn’t involve thinking too hard. Walking around alone wasn’t really his thing.
But he’d gotten bored. And when Denji got bored, he moved.
The streets were packed—salarymen dragging themselves home, students laughing too loudly, people bumping into each other like it was normal. It was noisy. Kinda annoying.
Denji shoved his hands into his pockets, glancing around without really looking.
Man… I’m hungry.
He’d eaten earlier, sure, but that didn’t really count. It never counted. He could go for something sweet. Or meat. Meat sounded good.
He clicked his tongue quietly, kicking at nothing as he walked.
He was wearing black pants and a loose white t-shirt he’d swiped from Aki Hayakawa. It was a little big on him, sleeves hanging just enough to be annoying—but whatever. Free shirt.
At least he didn’t stick out too much like this.
Not that he cared.
…Okay, maybe a little.
He turned behind a school, cutting through like it was a shortcut—and suddenly something slammed straight into him.
“—gh?!”
Denji stumbled back, more surprised than hurt. It felt like getting rammed by something way too fast for a normal person.
What the hell was that—?
There was a loud thud. Papers scattering. Someone hitting the ground. Denji blinked, then looked down. A guy. Around his age.
School uniform, messy now. Books everywhere. Backpack barely hanging off one shoulder like it was about to give up and fall the rest of the way.
Denji stared for a second. …Did he just run into me?
The guy didn’t move at first. Just kinda… lay there. Then he blinked. Slow. Like he was waking up or something.
And looked up. Their eyes met. Denji tilted his head slightly, still staring.
