Chapter Text
In the end, only the warrior remained.
His comrades had fallen—the brave, the foolish, the strong. Shadows devoured kingdoms. Empires burned to ash. Yet still… he stood.
The warrior's cloak fluttered in the storm's violent winds, torn and bloodstained. His blade—ancient, humming with forgotten power—gleamed under the crimson sky. Behind him? Ruin. Before him? The Beast. A monstrous thing older than time, all teeth and hunger, its roar shaking the heavens-
"Adam… hey. Wake up."
The warrior knew this was his final hour. Legends spoke of him—of the nameless human who defied fate, who challenged the darkness itself. And as the storm cracked and the world trembled—
A finger poked his shoulder, dragging him from the edge of destiny straight into the blanket-smothered reality of his bedroom.
"Come on, I need you to get up," Someone muttered, her voice low but rushed, words tripping over each other.
Adam groaned, squinting up at her. The hallway light made her look worse than usual—messy hair, oversized sleeping wear, eyes wide and twitchy.
"Alphys… it's three in the morning," he rasped as he looked at the alarm clock on his table.
"I know, but… look, I think Mew Mew's outside." She wrung her hands, glancing nervously toward the door. "Her bowl's empty, I forgot to pour milk, and you know how she gets when she's… hungry."
Adam stares at her "The cat that may or may not exist? That Mew Mew?"
Alphys' shoulders hunched defensively. "I… I heard something, okay? Out by the trash cans. I-It could be her." She shifted her weight, eyes darting to the window. "And, uh… it's really dark out there"
"Right," Adam sighed, dragging the blanket off himself. "And because you're scared of the dark, I get milk duty." He pulled on a jacket, feet hitting the cold floor. "For your imaginary cat."
"I never said she's imaginary," Alphys mumbled, stepping aside as he passed her while wearing the jacket. "I just never seen her before. But her milk keeps disappearing, and-"
"Y'know, fun fact," Adam cut in, rubbing a hand over his face as he shuffled toward the fridge, "most cats are lactose intolerant. So, either you've been poisoning Mew Mew this whole time, or that milk's just been disappearing into the void."
Alphys froze, halfway wringing her hands. Her expression twisted, somewhere between guilt and defensive panic. "I-It's... It's the thought that counts!" she blurted, tail flicking nervously.
"Besides, cartoons always show them drinking milk… I-I didn't think—" She trailed off, shrinking under his deadpan stare.
Adam grabbed the milk, already regretting being awake. "Yeah. That logic works great when your cat's fictional."
Alphys made a wounded noise in the back of her throat as he trudged toward the door.
The door creaked as he stepped outside, cool night air settling heavy over the cracked pavement. The alley stretched beside the trash bins, bathed in weak, flickering light from an old streetlamp. The clouds overhead hung low, blotting out the stars.
Adam exhaled slowly, dragging a hand through his messy blond hair, fingers catching on the knots from sleep. His palm came away cold, damp with the night air, and he shoved it back into his jacket pocket.
This was his life now.
Name's Adam. Or at least, that's what they called him now. Average guy, supposedly. Except most average guys didn't get the joy of doing life twice.
Long story short? He died and it didn't end there, though. He reincarnated.. One second, living your painfully normal, human existence, worrying about bills and deadlines—the next? Boom. New life in a new world.

The worst part? Doing it all over from scratch. He remembered enough of his past life to hate being a baby again. Drooling, flopping around, stuck staring at colorful mobiles while everyone treated him like a potato with limbs. The only upside was that creeping hum at the back of his mind—the awareness, the fragments of another life keeping him grounded, even if it made everything twice as exhausting.
There's also hell of a lot more monsters than he was used to. Literal monsters, not the metaphorical kind.
It took him a while to piece together. His mom's new husband was a literal dinosaur. Like, fangs, tail, scaless—the whole prehistoric package. His new stepdad was a nice enough guy though, he could give him that much credit. Certainly better than his biological father, who… yeah, not around anymore. It was complicated.
Everything was fine and dandy, for a while. But, nothing ever felt quite right. Everything seemed too familiar. Some of the faces around here, he could almost say he recognized them. Maybe it was just his imagination, he thought at first. Or maybe whatever god threw him here was lazy and used an existing template or something.
But then. He met her.
His adoptive step sister—Alphys. Yeah. That Alphys. Glasses, a nervous wreck, spends 90% of her time talking about anime and weird science projects that probably violate every safety regulation imaginable.
That's when it hit him. Monsters living amongst us, Alphys, it all added up. He thought for sure, knew, even, that he was reborn in an Undertale AU. Made sense, right? He even started connecting the dots. Guessing who's who. Figuring out where he fit into all this.
But then… Hometown happened.
Hometown was… weird. It was friendly on the surface, but it was drenched in that off-kilter vibe that clung to small towns where everyone knew your name—and your business. Where privacy was the exception, not the rule.
See, what happened was, his parents got busy with work. Real busy. Some overseas thing called them away—probably for the best, if he had to be honest. They've got enough on their plate without having to take care of a kid on top of it all. So, Adam ended up moving in with Alphys. Here, in this quiet, somewhat eerie little town where everything feels… off.
And that's when he realized… this isn't Undertale.
It's Deltarune.
If you don't know what that is… fair enough. He barely remembered half of it himself.
Deltarune is the second game made by Toby Fox. Same creator Of Undertale and definitely the same weird little dog mascot. Except, this one does not go by the same rules. Not the same world. Not the same story.
In Undertale, your choices could change everything. Kill or spare, fight or flee, how you treated people shaped the ending.
But Deltarune? Different deal entirely.
As the game itself loved to remind people—"You can't choose who you are in this world."
Adam mostly remembered Deltarune from the memes, if he was being honest. Kris and the player being two different people, Dark fountains, Some goat kid named Ralsei, Card Bowser and his son, Cancer or something. Robot Markiplier, and Tenna- He likes Tenna so Adam remembers him-, Dark Knight who could be the mayor or Dess, Asgore allegedly ran over Dess with a truck… or maybe that was just Twitter being Twitter. His memory of actual canon was a lot fuzzier than it should've been.
And wait—Toby Fox. The creator. If this was his world… Does that mean God is the annoying dog?
Adam grimaced at the thought, rubbing his temple.
Great. God is a yipping cartoon mutt with a stupid smile and an even worse sense of humor. That explained a lot.
Which means whatever rules he thought he understood.
Throw 'em out the window.
If he's right about where he is, and he's fairly certain, trouble will come whether he wants it to or not.
Starting with whatever the hell's digging through their trash right now.
His internal monologue came screeching to a stop as the low crunch of shifting trash echoed through the alley ahead. It was heavy, deliberate, like whatever was out there was searching for something. And it definitely didn't sound like some alley cat.
Peering through the gloom, Adam flinched as something large moved. Broad shoulders, rough scales catching the faint light. Clawed hands rifling through garbage with all the grace of a wild animal.
Definitely not a cat.
Adam exhaled, watching his breath fog in the cold.
"…Oh, it's you," he muttered. Loud enough for the one who's been rummaging through the trash could hear.
The figure stiffened. Yellow eyes gleamed as it turned—sharp fangs visible even in the low light.
Adam recognized her immediately.
Purple scales, messy bangs falling over one eye, She wore the same rumpled clothes he'd seen her stomp around school —a faded purple jacket hanging open over a white t-shirt with some worn, half-faded logo he couldn't make out. Torn jeans clung to her legs, frayed at the knees, and the heavy boots on her feet looked like they'd been through a few fights or kicked more than a few lockers.—the whole walking red flag package.
The kind of person you kept your head down around if you valued your teeth.
Susie. The school's infamous delinquent.
And right now she's caught elbow-deep in garbage, dumpster-diving like a feral animal at three in the morning.
Her eyes flicked to the milk in his hand, then back to his face, unreadable.
Adam exhaled through his nose, lifting the jug slightly. "So you're Mew Mew, huh?"
The alley stayed quiet except for the faint hum of the streetlamp overhead, its flickering glow stretching long shadows over the cracked pavement.
Figures.
His first real run-in with trouble since moving here… and it's her. The supposed second protagonist of the game. His classmate. Currently neck-deep in trash like some kind of raccoon
Just his luck.
