“ding!” [ undertale x reader ]

series masterlist : [here] | chapter one

summary: you can’t sleep, and at 3:49 AM, a notification pulls you into a mysterious group chat called UnderChat. the members—quirky and chaotic sans au’s like ink, fresh, and error—welcome you as their newest recruit, insisting you’re from an alternate universe. confused but curious, you hesitate to believe them, wondering if you’ve stumbled into the strangest roleplay or something more.

3:49 AM

That was the time, obviously. You were not catching a wink of sleep tonight, even though those eyes of yours were pratically burning at this point. Blinking at the bright light which popped up when you clicked a notifaction. "DING!" echoed the phone on full volume: You were just about to scroll through tumblr aud—

Oh.

Oh. . 

You've been added to a groupchat.

Immediately sitting up you rubbed your eyes, curiousity gleaming in them.

UnderChat 

You don't remember downloading that app. . Perhaps you accidentally clicked on one of those explicit advertisements on accident while reading on pirated websites, that seems like a plausible explanation. Still doesn't explain why you're recieving notifactions saying your in a groupchat. A groan escaped your lips as you clicked the notifaction, although accepting the fact this was some sort of call-out cancel groupchat, an accidental add, or it's fake and it's a virus. Probably the latter.

[ SLEEPRLUVR has joined the group ]

FunkN'Fresh: wellllp ill be diddly darn darned we gots a new funky fresh membah?

GlitchBitch: Stop typing like that.

FunkN'Fresh: noo can do funny magic maannnnnnnnn

[ GLITCHBITCH has muted the groupchat ]

FunkN'Fresh: you maaaaaaad.

Ink: Oh! New member yay, Okay so I can explain this as your probably confused sans!

Ink: Eheh, "how do you know my name" you might ask! wellllp, yknooow the multiverse and all that stuffs? We made a groupchat!

SLEEPRLUVR: what? 

Ink: Okay so a basic run down of how the app works, the three icon's at the side shows you every AU that has joined so far and what their username is - You need to create a profile with yours!

SLEEPRLUVR: what

Ink: Oh— You must still be confused, I'll just do it for you! What AU are you from?

SLEEPRLUVR: what.

Ink: ...

Fell2cool4school: prolly from "what"!tale lmfao

SLEEPRLUVR: no, just wasn't expecting roleplayers in my schedule today. i can do this - what aus are open?

.

.

.

The chat suddenly went dead silent, leaving you staring groggily at your phone, squinting at the screen. You couldn't help but wonder what was going on. Does it really take this long to grab a character masterdoc? It's been a while since you last roleplayed, but this felt off. When the next message finally popped up, you couldn't help but roll your eyes. 

⋆⁺₊⋆ ━━━━⊱༒︎ • ༒︎⊰━━━━ ⋆⁺₊⋆

Ink: Oh, uh... this isn't exactly roleplay, but I get why you'd think that! Anyway, we’ve got a lot of AUs here, so take your pick! Let’s see… there’s Underswap, Underfell, Dancetale, and even some wacky ones like Dusttale and Underlust, but let’s not go there unless you’re into, well, *that* kind of stuff. 

SLEEPRLUVR: ...i’m just going to ignore that last part.

Fell2cool4school: aww c’mon, why skip out on the fun? 😈

SLEEPRLUVR: This is ridiculous. Okay, so let's say I believe this whole “multiverse” thing. Why am I here?

Ink: Well, every AU needs a representative! Think of it like... a council! Each universe gets one member to join the chat, share ideas, keep peace, y’know? And... well, you’re the lucky one picked from your AU!

SLEEPRLUVR: but i don’t even know what AU i’m from. how am i supposed to “represent” it?

FunkN’Fresh: uhhh doesn’t seem too funkay to me, guess they jus got dropped here like a beeboppin’ newbie!

GlitchBitch: Figures. Another clueless one. Just what we needed.

Ink: Don’t mind them! We’ll figure out your AU together! It’s kinda exciting, right?

SLEEPRLUVR: mmm, more like nerve-wracking. can i leave?

Ink: Nope! Once you’re in, you’re in. But don’t worry, we’re all friends here! ...Sort of.

Fell2cool4school: speak for yourself, inkhead. i ain't here to make friends. only enemies. and sometimes frenemies. but mostly enemies.

SLEEPRLUVR: yyyeah, i’m definitely going to regret this. okay, so if I’m stuck here… how do I create this profile thing?

Ink: Just tell me a bit about yourself, and I’ll set it up for you! Favorite color? Likes? Dislikes? Any cool abilities? C’mon, spill!

SLEEPRLUVR: umm… favorite color? any, I guess. Likes? Sleeping. Dislikes? Waking up. Abilities? being normal???

GlitchBitch: Abilities: None. Fitting.

Ink: rainbow, sleeping, normal. Got it! I’ll just make your profile super quick…

FunkN’Fresh: "likez sleeping" heh. typical standard sans bruh.

[INK is typing…]

Ink: Done! Welcome to the UnderChat, SLEEPRLUVR!

SLEEPRLUVR: …i’m going to need a lot of coffee for this, aren’t I?

FunkN’Fresh: forget coffee, maaaaan. get some soda in yer veins, get the funky fresh groove goin’!

GlitchBitch: Or you could just log off and get back to your irrelevant existence. Just saying.

SLEEPRLUVR: …i’m starting to think leaving this group would be the sanest option.

Fell2cool4school: too late for that, buddy. you're one of us now. welcome to the madness.

     You sat on your bed, legs crossed beneath you, staring at the screen with a mixture of bewilderment and curiosity. That was... ermmm, certainly an experience. These people seemed like some serious kinnies or something. You hadn't seen roleplayers this deep in character since the wild days of Danganronpa Kokichi Tumblr drama. You gnawed at the inside of your cheek, debating your next move. You had things to do in the morning, so maybe it would be smart to just get some sleep. But then again—shouldn’t you figure out which AU to be? They didn’t even give you a proper list of what was available!

     You could at least deduce a few things. Obviously, GlitchBitch was the Error Sans of the group, with his snarky, broken-text vibes. Ink was, well, Ink, and FunkN’Fresh was soo stereotypically hippie, it was a dead giveaway who he was supposed to be. But who else was in this group—this "UnderChat" as Ink called it? And how were you supposed to see these profiles they mentioned? The whole thing was making your head spin, trying to figure it out.

     Still, as you finally set your phone down and pulled your covers over you, you couldn't help but feel a small smile tugging at the corners of your lips. Yeah, it was weird—being added to some mysterious group chat by what seemed like over-enthusiastic roleplayers—but there was something almost... nostalgic about it. It had been a while since you just sat back and played pretend, no matter how weird the scenario... or old the fandom was.

     Maybe tomorrow you’d hit up the Undertale Wiki and find a cool AU to rp as. After all, if you were going to be stuck here, you might as well have some fun with it.

* A/N: uhm, this was written for ao3 and crossposted on quotev and now we're here. it looks best, imo, on quotev because it comes with extra media!! but im here because ppl can send asks n stuff for extra content of the skellies. please reblog or comment , it helps my motivation

HIHI i was thinking about your fic and was wondering, what would be the reaction frm the guys with a yn more mean? Like, they told yn to come to a party with them and yn answer "why would i want to be near You guys lmao"

swings legs i had fun with this one pls read until end for longer snippet !!

“How would the sans' react to a meaner MC?”

pairings; undertale sans aus/mean reader

cw; made with ding!sans' in mind, they're from my fic which you can find on my page. can somewhat be read alone.

You’re quick to deliver sharp, biting remarks, often pointing out flaws or poking fun at the others.

Fresh: At first, Fresh laughs it off and tells you how unrad it is, but you notice his responses slow down over time. You almost think you had hurt his feelings—not that you'd care, but then... Eventually, he starts countering with his own brand of overly chipper sarcasm. 90's insults and the whole shabang. “Jabroni!” “Bozo!” He’d text quick wittedly and honestly, you felt as if he didn't take you seriously at all!

Ink: Ink acts unbothered, but his emojis start feeling a little more passive-aggressive after each comment. He eventually flat-out asks if you’re always this “charming.” (Hint: yes, you are.)

Anytime someone gets excited about something, you’re quick to brush it off as “boring” or “childish.”

Blue (Swap): At first, Blue is genuinely hurt. He tries to win you over with kindness, but when it doesn’t work, he grows more defensive. “Well, at least I’m not a grouch like you!” Except this doesn't get taken that seriously through text messages, he made many typos while mad. Embarrassment sunk in his skull.

You don’t sugarcoat anything. If someone asks for your opinion, you give it to them straight—even if it stings.

Fell: While the others struggle with your bluntness, Fell almost seems to respect it. “Finally, someone who knows how to talk without all the coddling. You’re still a pain in the ass, though.”

Your humor leans sarcastic and borderline cruel, often making fun of situations or people when they least expect it.

Mutt (Fellswap Papyrus): Mutt starts out confused but eventually laughs along, he was used to his brother somewhat acting this way anyways. “i can’t tell if yer joking or just heartless. either way, i respect it..”

The Skeletons Get Used to You

Over time, the group adjusts to your personality. While the initial sting of your remarks still lingers, they realize that your meanness isn’t necessarily personal—it’s just who you are.

Fell outright calls you out one day: “At least I have the guts to say it to someone’s face. You just hide behind a screen like a coward.” Surprisingly, his bluntness makes you pause. After that, the two of you develop an odd sense of camaraderie, bonding over your shared abrasiveness. But, in your defense, it's not even like you could say anything to any of their faces—it was a groupchat! An online one!

Blue learns to dish out sass in return, though he’s not nearly as sharp as you. “Hah! See? I can be tough too!” It’s almost endearing how hard he tries to keep up.

Overall; the skeletons gradually adjust to your mean-spirited personality, finding it strangely entertaining rather than off-putting. For you, being snarky behind a screen is easier than dealing with the judgmental stares of real life. At first, your bluntness catches them off guard, but having already dealt with Fell’s abrasive honesty and Error’s sarcastic tendencies, they learn to roll with it.

───────────────────────────────────

Ink: we should do introductions!

You: pass.

BlueberryBoi: that’s no way to make friends!

You: i’m not here to make friends. isn’t that obvious?

GlitchBitch: ok, but why’re you still here if you hate us so much?

You: free entertainment. like watching a bad soap opera.

Ink: :\

───────────────────────────────────

BlueberryBoi: hey, what’s your favorite color? i wanna know more about you!

You: it’s not blue, if that’s what you’re fishing for.

BlueberryBoi: why would that be what i’m fishing for?!

FunkN’Fresh: dang, blueberry got roasted!

You: relax, fresh. you’re next. how’s it feel living in 2010 with that personality?

FunkN’Fresh: YO YOU DIDN’T HAVE TO GO THAT HARD!!

ISTHATTHEGRIMREAPER: this is just sad at this point.

You: what’s sad is your edge level. did you write this chat on a black notebook with skull doodles in the margins?

DANCETILLURDEAD: ok but that’s actually kinda funny.

You: congrats, first compliment of the night. don’t get used to it.

nastydawg: i’m crying.

───────────────────────────────────

Ink: it’s been a while since we had someone meaner than fell in here…

Fell2cool4school: correction: i say it to yer faces. this coward hides behind the screen.

You: pretty big words coming from an off-brand tsundere.

FunkN’Fresh: HAHAHA TSUNDERE FELL

Fell2cool4school: say that again, and yer dead.

You: aw, did i hurt your feelings?

───────────────────────────────────

FunkN’Fresh: hey brah, we’re watching a movie later. wanna join?

You: nah.

Fell2cool4school: you always say no. do you do anything fun?

You: yeah, but it doesn’t involve hanging out with people like you.

Fell2cool4school: just admit it. you’re scared we’ll out-snark you.

You: yeah, i’m terrified. let me go cower under my desk real quick.

ISTHATTHEGRIMREAPER: ngl, that sounds like a yes.

BlueberryBoi: i think you secretly like us!

You: doubt.

───────────────────────────────────

Ink: so you coming to the movie night or what?

You: didn’t i already say no? you forget things a lot for someone with so many brains.

Ink: nah, just figured you’d be too lonely to say no twice.

You: …ok, that one wasn’t bad.

FunkN’Fresh: WHOA, INK GOT A POINT!!

BlueberryBoi: hey, if you hate us so much, why’re you always online?

You: you’re that one annoying ad you can’t block.

BlueberryBoi: that doesn’t even make sense!!

Fell2cool4school: neither does their personality. move on.

You: says the guy who named himself “fell2cool4school.”

───────────────────────────────────

You had just logged off your last class for the day, stretching as you leaned back in your chair. The soft hum of your computer faded into the background as your phone buzzed on the desk. That group chat again.

Despite how bizarre it all was, you hadn’t left yet. Something about their antics kept pulling you back—though you weren’t sure if it was curiosity or sheer disbelief at their personalities. You picked up your phone, thumb swiping to open the app.

ISTHATTHEGRIMREAPER: yo, who’s up for a party tonight?

FunkN’Fresh: YO YO YO!! PARTY?? sign me UP, my dudes!

Ink: Party? Who’s hosting??

Fell2cool4school: tf u need to know for? either you’re in or you’re not.

nastydawg: bet it’s just some lame excuse for you to brood.

You couldn’t help but scoff. A party? With them?

You already knew where this was going. The thought of actually hanging out with the loud, chaotic group made your head hurt.

Before you could mute the conversation and move on with your evening, another message came through.

Ink: protégé, you coming?

GlitchBitch: doubt it.

DanceTillUrDead: um, we haven't even seen their face yet..

fell2cool4school: shut up remix no one likes u

DanceTillUrDead: i didnt even say anything :(

FunkN’Fresh: c’mon, protégé! it’ll be fresh. gotta let loose sometimes, you feel?

ISTHATTHEGRIMREAPER: yeah, don’t be lame.

The barrage of messages made you pause. Did they actually think you’d go? You glanced at the messages again, your lips curling into a smirk. If they were expecting you to jump at the invitation, they had another thing coming.

You typed quickly, the sarcasm practically dripping from your fingertips.

You: why would i want to be near you guys lmao.

The chat went silent for a moment. Then:

Fell2cool4school: lmfao

Ink: 😐

nastydawg: damn, that’s cold.

You could almost picture their faces—well, if skeletons had proper faces. Maybe they weren’t used to being called out like this.

FunkN’Fresh: WHOA OKAY, rude.

ISTHATTHEGRIMREAPER: not rude lol, just pathetic. they’re too scared to hang with us.

You raised an eyebrow at the message. Scared? Hardly. But the baiting tone was hard to ignore.

You: scared? pls. i just don’t waste my time.

Fell2cool4school: says the one still sitting here reading our messages.

You grit your teeth. Fell’s words hit a little too close to home, and you weren’t about to let him get the last word.

You: nah, i’m just here for the free comedy show.

gotta say, you guys are top-tier entertainment.

The chat erupted into a mix of responses.

nastydawg: ok but this is funny

Ink: yeah, hilarious.. /s

GlitchBitch: stop fueling them, mutt.

FunkN’Fresh: YO PRO, i’ll have you know i’m like, the LIFE of any party!! you’re missing OUT, my dude.

You: i’m sure. let me know when the clown

show starts, maybe i’ll swing by.

You set your phone down, satisfied. The chat was still blowing up with messages, but you ignored them. They wanted to play games? Fine. You weren’t about to make it easy for them.

Still, as you leaned back in your chair, you couldn’t shake the faint curiosity lingering in your chest. For all their weirdness, you wondered what they’d actually be like in person.

But you weren’t about to admit that—not to them, and definitely not to yourself. Why are you even wasting your precious time with some dumb no life roleplayers anyways.

[somniseeker]

Anon who commented on most of the AO3 chapters here: if possible. Can we request POV of the other skeles or the other characters? If so, may I request Geno pov from chapter 6 on your Ding fic! I’m also going to assign myself the 💀 or the🧣anon nickname for well. Talking with you about Reaper and Geno in the comments section. So it is easy to identity myself for you amongst the other anons so you don’t presume all of them are me. XD

alr!!! ill stop assuming every anon is u LOLOL .. arghghgh ur literally such a smarty pants i would’ve never thought of writing this!! anyways ofc i can do chapters from charas povs!! im glad i could write this as i haven’t really gotten to write much of geno!! and heres sprinkle sprinkle of reaper because the two are the bestest ever i love them. headcannons & more of their dynamic soon!!!

“chapter 6 of ding! from geno's pov.”

c/w; you’ll be a little confused if you haven’t read ding! otherwise, its fine.

───────────────────────────────────

Geno sat in the stillness of Reaper’s universe, his bones relaxed for what felt like the first time in ages. A warm cup of peppermint tea, its steam lazily drifting up in the air, sat comfortably in his hands. The aroma was earthy and calming, something he didn’t think he'd ever truly appreciate until now. It was a moment of peace he hadn’t known he craved, something that had seemed so far out of reach for so long.

The universe around him was quiet, filled only with the soft hum of existence. The void stretched endlessly, a place where time didn’t move quite the same, and nothing was urgent. Geno leaned back, his skull tilted slightly upward as he closed his eyes, savoring the simple act of not needing to worry about anything. For once, there was no battle to prepare for, no new timeline to navigate. It was a rare, fragile peace.

He took another sip of his tea, the warmth sinking deep into his bones. For all the complexity and chaos that had marked his journey, this... was nice. He hadn’t realized how much he needed this, a quiet day with no expectations.

The quiet was interrupted only by the occasional shuffle of Reaper nearby, a figure who, despite his seemingly cold demeanor, had become more than just an acquaintance. Reaper’s presence had been a constant through Geno’s darker moments. There was something about Reaper, a way he moved through life—or unlife—with such quiet confidence that Geno couldn't help but gravitate toward it.

For all the time they’d spent together, it was hard to pinpoint when their connection had deepened. Maybe it was when Reaper first showed up and inserted himself into Geno’s life. Maybe it was when they had sat like this before, sharing silence and tea, just... being. It didn’t matter. What mattered was that, in this vast, seemingly endless universe, Reaper had become a constant in a way no one else had.

Geno glanced over at him now, catching the faint glimmer of something in his friend’s gaze. Reaper was texting the Underchat. but Geno knew him well enough to recognize it. The group chat had been suspiciously quiet all day—a sign Geno had learned to interpret as the calm before the inevitable chaos. Sure enough, the moment Reaper settled on the couch beside him with his laptop, the notifications started rolling in again like clockwork. Geno opened the chat on his phone, already bracing for the nonsense.

Reaper was grinning at his screen, fingers flying over his keyboard, clearly up to no good. Geno sighed, leaning back against the cushions, his phone balanced lazily in one hand.

“You’re playing Uno again, aren’t you?”

Reaper didn’t even bother looking up. “Of course. And I’m winning, obviously.”

“Winning,” Geno repeated flatly. “That what you call it when you’re glitching the deck?”

Reaper’s grin grew wider, more infuriating. “Creative solutions, Geno. Nothing in the rules against them.”

He glanced over at Reaper, who was laughing to himself, clearly enjoying the chaos he was stirring up. "You’re enjoying this way too much."

"Of course I am," Reaper said with a shrug. "It's not about the winning, you know. It’s about the reactions."

Geno sighed. "You sound like Ink."

Reaper gasped in mock offense, clutching his chest as if Geno had mortally wounded him. "How dare you compare me to him! Ink's chaos is messy. Mine? Mine is art." Geno thought it was quite ironic Reaper compared himself towards art more than Ink, a literal artist and creator—who’s entire existence revolves around that fact.

"Yeah, yeah, sure," Geno muttered, though he couldn’t help the small smirk tugging at his mouth. It was hard not to find Reaper’s antics at least mildly amusing, even when they were as infuriating as this.

Geno rolled his eyes, scrolling through the chat to catch up on the unfolding drama. Sure enough, Error was already losing it.

GlitchBitch: YOU GLITCHED THE DECK, I SAW IT!! THAT DRAW FOUR WASN’T EVEN IN THE GAME UNTIL YOU ADDED IT!!

Geno’s head tilted slightly. “You added cards to the deck? That’s... bold, even for you.”

“Bold?” Reaper repeated, as though tasting the word. “I prefer innovative.”

“More like insufferable,” Geno muttered, his tone dry. He watched as Error continued to spiral, Blue tried to calm everyone down, and the newbie—Protégé—typed in with what was clearly genuine confusion:

SLEEPRLUVR: wait how do you cheat in uno?? isn’t it all luck and strategy?

Geno blinked. Oh no.

Beside him, Reaper cackled softly, his fingers dancing across the keyboard. Geno didn’t even need to see the screen to know his next message would be dripping with smugness.

ISTHATTHEGRIMREAPER: ah, protégé! it’s good to see you’re as naïve as always. 🙏

Geno sighed loudly, leveling an unimpressed look at Reaper. “Really? You’re laying it on that thick?”

Reaper glanced over, his expression all too pleased. “What? I’m just addressing them by name. The name you gave them.”

“You’re addressing them like you’re in a bad soap opera,” Geno shot back. “You do realize they’re already out of their depth in this chat, right? When I was new to the group chat I nearly had a meltdown. You’re gonna give them an existential crisis.”

“Relax, Geno,” Reaper said with a dismissive wave. “I’m just being charming. No harm in that.”

Geno didn’t respond, opting instead to keep scrolling through the chaos. Error was ranting, Blue was pleading for everyone to calm down, and Protégé was clearly trying to keep up. Then came the message that made Geno pause mid-scroll.

ISTHATTHEGRIMREAPER: 😘 for you, I’ll consider it.

Geno’s screen dimmed as he stared at the message. For a long moment, his expression didn’t change, but internally, his thoughts were a whirlwind of confusion and disbelief. Slowly, he turned his head toward Reaper, who was leaning back on the couch, his grin practically radiating smugness.

“You’ve got to be kidding me,” Geno said finally.

“What?” Reaper asked, all faux-innocence.

“You just—” Geno gestured at the screen. “You flirted with them.”

“It’s harmless fun,” Reaper replied, his tone light. “Why so serious, Geno?”

Geno’s jaw tightened briefly before he let out a long, slow sigh. “Do you realize what you just did? They’re probably overthinking that message right now.”

“Oh, come on,” Reaper said, a laugh bubbling under his words. “They’re fine.”

“They’re spiraling,” Geno corrected, turning his phone to show Reaper the flurry of messages Protégé had started typing and deleting. Protégé hadn’t said anything after that, but he could see the three typing bubbles appear and disappear. “See? This is what I’m talking about. You can’t just throw stuff like that out there.”

Reaper waved him off. “If anything, I’m helping them adapt. Survival of the fittest, Geno. They’ll thank me later.”

Geno rubbed his temples, the faintest hint of a smirk tugging at his lips despite himself. “You’re ridiculous.”

“You’re entertained,” Reaper shot back, eyes twinkling.

Geno couldn’t deny that. For all Reaper’s chaos, there was something almost... comforting about it. Predictable, in its own twisted way. Still, he couldn’t let him off the hook completely.

Opening the chat again, Geno typed out a single message.

alivebutimdead: wth

Reaper chuckled at the screen, clearly unbothered. “That’s all you’ve got to say?”

“It’s all that needs to be said,” Geno replied, his tone dry. He leaned back against the cushions, watching the chaos unfold as Reaper continued to fan the flames.

A soft hum of amusement escaped him as he caught sight of Protégé’s latest message—an obviously confused, probably oblivious response to Reaper’s earlier flirting. He sighed, shaking his head. “You’re really enjoying this, aren’t you?”

Reaper didn’t even pretend to deny it. “Of course. You should be too, Geno. Life’s too short to take everything so seriously.”

“Someone has to be the adult in this room,” Geno muttered, though there was no real heat behind his words.

Reaper laughed, leaning back with his arms crossed. “And you wear that title so well.”

Geno shook his head, exasperated but oddly fond. For all his frustration, he knew Reaper didn’t mean any harm—it was just his nature to stir the pot. Still, Geno made a mental note to keep an eye on Protégé. Reaper’s chaos could be a lot to handle, especially for someone new.

───────────────────────────────────

EXTRA SNIPPET

Geno sat at the small, dimly lit desk in his room, a mug of lukewarm tea sitting untouched to his right. The group chat notifications had gone silent—Reaper was busy dragging Error and Ink into whatever chaos he’d concocted, and Geno, well, he wasn’t in the mood for it. Too many personalities in one room was overwhelming at the best of times, and tonight, he just wasn’t up for it.

But sitting alone left him with the faint, nagging itch of boredom. He rested his chin in his hand, glaring at the scattered cards on the desk in front of him.

"Uno," he muttered under his breath, the word sounding strange and foreign. He picked up the little rulebook he’d printed off from some online source, flipping through the pages for the fourth time. “Simple game,” Reaper had called it. “No-brainer,” he’d said.

Geno squinted at the rules, his sockets narrowing. “How is this simple?”

The bolded letters on the page mocked him. Match colors or numbers, use special action cards to disrupt your opponents, and remember to call ‘Uno’ when you’re down to one card.

“Sure,” Geno muttered. “Sounds easy enough. Except—” He gestured at the cards spread out before him in frustration. “What is a wild draw four? And why are there so many skip cards? Why do I skip myself?”

The room was silent, save for the soft ticking of a clock on the wall. Geno picked up a random stack of cards and shuffled them awkwardly. It wasn’t smooth, but it worked well enough. He laid them out again, trying to simulate a game.

“Okay. If I have a green three and a blue three... does that mean I can stack them? Or is that against the rules?” He frowned, flipping back to the rulebook. “Oh. I can’t. But... why not? It makes sense to me.”

He leaned back in his chair, staring at the pile of cards like they’d personally offended him. His sockets drooped slightly in resignation. “This is stupid,” he mumbled.

Still, his curiosity gnawed at him. Reaper always made Uno seem so effortless, like a game of chess he was five moves ahead in. Geno couldn’t help but wonder what it was like to understand the strategy—or to use it as shamelessly as Reaper did.

He picked up a wild card and held it up to the dim light of his desk lamp. “Change the color to anything you want. That’s great and all, but what’s stopping someone from just picking whatever’s best for them? No wonder Error loses his mind when Reaper plays.”

The thought of Reaper’s smug grin made Geno’s scowl deepen. He imagined Reaper leaning over his shoulder now, laughing at his pathetic attempt to piece together the game. “Creative solutions, huh? What would your ‘creative solution’ be for this?” he muttered under his breath.

Sighing, he gathered the cards and shuffled them again, this time slightly more smoothly. He laid them out into two fake “hands,” playing against an imaginary opponent.

“Okay,” he muttered to himself, placing a red eight down. “Red eight. If I had a yellow eight, I could play it, right? But... let’s say I don’t. Do I draw? And if I draw, do I—ugh.” He rubbed at his temple, glaring at the card like it might suddenly start explaining itself.

This was hopeless.

Geno groaned, slumping forward until his forehead rested against the desk. “Why am I even doing this?” he mumbled. His voice echoed faintly in the quiet room.

The group chat pinged, drawing his attention. Reaching for his phone, he saw a new message from Reaper.

ISTHATTHEGRIMREAPER: having fun all by yourself, geno? ;P

Geno scoffed. “He always knows, doesn’t he?”

He tapped out a quick reply.

alivebutimdead: better than getting dragged into your nonsense.

ISTHATTHEGRIMREAPER: ouch, gen. if you’re lonely, just say so.

alivebutimdead: i’m fine. go bother error.

The typing indicator appeared, then disappeared, then reappeared again. Geno could almost see Reaper’s smirk through the screen.

ISTHATTHEGRIMREAPER: tell me you’re not trying to learn uno by yourself.

Geno froze. He glanced at the cards spread out on the desk, then back at his phone.

alivebutimdead: ...what if i am?

It didn’t take long for Reaper’s reply.

ISTHATTHEGRIMREAPER: 😭😭😭 geno, you wonderful idiot. wait for me, i’ll teach you.

ISTHATTHEGRIMREAPER: you never read uno instructions lol, everyone has different rules.

Geno rolled his eyes, but his expression softened slightly. Despite his frustration with the game—and with Reaper’s incessant teasing—there was something oddly comforting about knowing he wasn’t entirely alone in this. How was he supposed to know everyone had different rules? What was the point of the instructions then… Whatever.

Setting his phone down, he leaned back in his chair, a small, wry smile tugging at his lips. “Guess I’ll have to survive your version of a lesson,” he muttered to himself.

For now, though, the cards could wait.

Heyy so, i was reading your story and, how they would react if reader just send something like "hey can i change my character???" Or a photo with a fanart in where u can see that they're a human!!!! i'm sorry if this is too long or the answer has spoilers it's just that while i was reading i NEEDED something like that😿

hihihiii!!! this ask is not cannon and does not affect the current story !! sorry its so short but i don’t want to potentially spoil the actual story !~ btw dont be sorry!! i love imagines/asks 🤍

“What if reader asked to change their 'character'?”

pairings: n/a

this is not cannon, but you need to read the fic (ding!) to understand it !

The screen’s glow illuminated your dimly lit room. You had been pacing back and forth for hours, debating your next move. CollegeTale Sans had been fun to think about for a while, but the longer you stayed in the UnderChat group, the more you realized how little you enjoyed being tied to the concept of school. It wasn’t like you even liked college that much—you only picked the persona because it seemed safe.

You didn’t even like college that much—why would you want to pretend to be a version of Sans who’s in it?

You groaned, running a hand down your face. "This is so dumb," you muttered. "Why did I even think this was a good idea?"

Finally, with a heavy sigh, you plopped into your chair, opened the group chat, and typed:

SLEEPRLUVR: hey... so... i’ve been thinking about this all day

SLEEPRLUVR: can i change my character???

The chat went still. For a second, you thought maybe no one saw the message. Then:

ISTHATTHEGRIMREAPER: what

Fell2cool4school: ????

alivebutimdead: change... your what?

GlitchBitch: lmao what r u talking about???

Your fingers hovered over the keyboard, heat rushing to your face. You tried to explain, typing quickly before anyone else could respond.

SLEEPRLUVR: okay so i don’t rlly like collegetale sans anymore, there’s not much info about him online and idk how to be “in character”

SLEEPRLUVR: and like i don’t even like school irl, so i was thinking of switching to a sans i connect with more??

SLEEPRLUVR: here’s the one i was thinking of

You attached an image of your computer screen showing a piece of fanart showing Ccino Sans from Fluffytale, holding a coffee cup and wearing his signature barista apron, cozy vibes radiating from the character.

It felt like a good choice—simple, cozy, and much easier to relate to.

The chat exploded almost immediately.

Fell2cool4school: HAHAHAHAHAHA

Ink: oh my god are you serious??

FunkN'Fresh: yo. YO.

ISTHATTHEGRIMREAPER: wut

GlitchBitch: …this cannot be real

You frowned, staring at the messages. Why are they reacting like that? Before you could ask, a new notification popped up:

Fell2cool4school: @cattuccino 🐾 , COME ONLINE TWERP.

[ CATTUCCINO 🐾 has come online! ]

cattuccino 🐾: wha???

Your stomach dropped.

cattuccino 🐾: why is my face here? what’s going on???

Oh no. Oh no, no, no. You stared at the chat in horror as embarrassment crept up your spine. They already had another Ccino sans? That's embarrassing for you - but then, why the reactions? Was it really that bad to have multiple people roleplay one character?!

Your hands froze on the keyboard, hovering uselessly as panic crept up your spine.

You reread the past messages.

Realization hit you like a truck. No. No way. This can’t be real. This has to be a joke.

Ink: …wait.

Fell2cool4school: …

alivebutimdead: uh. okay, hold up.

GlitchBitch: ...what do you mean by “character?”

You wanted to disappear. The room felt suffocating, and your laptop screen seemed to grow brighter, as if to mock you. With shaking hands, you typed:

SLEEPRLUVR: um. uh. it’s a joke??? haha jk nvm i’m staying collegetale!!!!

SLEEPRLUVR: yk me! always joking, like sanses do.

Oh yea, you're a bad liar.

Ink: don’t lie to me

The sharpness of his words made your chest tighten.

Ink: you’re not a Sans, are you?

Your breath hitched. You felt exposed, vulnerable, like a deer caught in headlights.

alivebutimdead: wait… what.

Fell2cool4school: hold up. you’re not a Sans?

ISTHATTHEGRIMREAPER: ....lmao we're all fucked

GLITCHBITCH: i knew this was a bad ide.

FunkN'Fresh: yo. YO. THIS IS REALLY BAD BRAH.

cattuccino 🐾: someone explain what’s happening???

Your head spun, the chat messages blurring together. This wasn’t happening. This couldn’t be happening. Your fingers trembled as you tried to explain.

SLEEPRLUVR: no no no, i totally am! i’m just—

Ink: don’t

The single word felt like a slap.

Ink: you’re not one of us. you’re not even supposed to be here. how did you get into this chat?

You swallowed hard, feeling the heat of embarrassment and dread crawl up your neck.

Fell2cool4school: yer joking right

ISTHATTHEGRIMREAPER: obviously not dumbass

alivebutimdead: this… this is bad. like, timeline-breaking bad.

GlitchBitch: you’re telling me this random human just stumbled into a multiverse chat???

SLEEPRLUVR: I didn't stumble into this chat-- I was added! I just saw the app pop up one day!

cattuccino 🐾: …they’re human??

Your pulse quickened. The word "human" hit like a hammer. They knew. They all knew.

Ink: do you have any idea what you’ve done?

Your stomach churned as you tried to type, but nothing came out. The enormity of the situation crashed over you like a tidal wave.

Ink: we need to fix this

SLEEPRLUVR: fix this? what does that mean?

Ink: it means you don’t belong here. we need to figure out how you got in and get you out. now.

The reality of what you’d done hit you like a punch to the gut. This wasn’t fun or exciting anymore—it was terrifying. Your mistake wasn’t just embarrassing; it was dangerous. You’d crossed a line you didn’t even know existed. You didn’t ask to be added to this app! You didn't know it wasn’t a roleplay so why are you getting the repercussions for a mistake!

You have a bad, bad feeling about this.

Are we gonna see more Horror, Classic, Remix, Outer or other sanses that aren't really mentioned more often? I was just wondering if there was a particular reason they aren't mentioned as much. (Talking about ding!)

im so glad you asked!!! yes you will see these sans' more often as the fic progresses. since the story is set up like a chatfic mostly, it only makes sense to have the more chatty au's have more texts and stuff yk? but heres a better explanation behind every character!

i dont see dancetale sans being the type to want to text or talk a lot, i see him as not that social! lame lazy excuse but that's genuinely the reason why he hasnt been mentioned a lot. hes one of my favs tho <3

in my au, i also dont see classic sans as someone who was very ecstatic to know there was alternative universes of him - i think he knew of the theory, but was still a little creeped out to know he was the very original one. so he's not very active in the groupchat, preferring to talk to paps and stay in his own au.

as for horror sans, hes a fan favorite. i know that for sure. but then again, hes another sans i dont see being interested in texting a lot. i can see him reminding the others to eat or just like, hovering and lurking in the messages but i don't see him as an active member of the chat. he probably knows who protégé is by now and their personality, just from lurking lol.

outer sans, eeek i had so much planned for this guy </3. this one i dont actually have a good explanation for. i owe him some justice, dont i... he hasnt even been properly introduced in the main story...

overall, i plan on making these characters have more appearances as we drift away from text-based interactions. i dont want to spoil anything, but you'll be definitely be seeing more of them in future chapters. i want every sans to have their own personality thats fleshed out in this story, so it might take some time to do that. you probably have realized certain sans' have gotten more attention in earlier chapters! thats who im focused on rn.

[somniseeker]

squinting on whether or not i should remove a part of my fic (new chapter being written). i want mc to be applicable to everyone but theres a part that mentions mc's hair. what if one of my readers are bald or has a buzzcut. hmmmmm

its a couple hundred words but i dont mind changing it tbh .... ill post the draft one as an extra on tumblr/here tho if i get rid of it
