Dusted, a RWBY age change story
GK: *currently working on something* oh, you again, whatever, I'm used to you being here at this point. I'm just finishing up what i need for my next plan to work. An acquaintance of mine asked me to swap the ages of rwby characters Yang and Ruby. Now, i wouldn't call this an age swap, the two girls are only a few years apart so I'm gonna make it a little more interesting for myself. Oh also *looks at the screen* you know who you are, sorry if this wasn't what you expected, this was just the simplest way i could do this with it having any real effect. Plus it makes it about 110% easier for me to come up with.
*a few minutes later*
GK: okay it's ready, now let's get on with this. This is happening just after season 5. And if this isn't exactly what you wanted, then there's always another timeline i can work with to make the exact story you want if the outcry for it becomes big enough. Or, whatever. Also, quick warning, i like these characters a lot, so there isn't gonna be any big downside for one or the other honestly.
*after the battle for haven team rwby had a short bit of down time, and a delivery of what should've been just a restock on dust for their weapons, brought changes that could never have been expected*
Ruby Rose: hey, looks like the dust we ordered is here.
Yang: cool, make sure everything's there.
(Short time distributing the dust later)
Ruby: hey, it seems there's an extra box here.
Yang: really? There shouldn't be, might want to send it back.
Ruby: but it's addressed specifically to us sis.
*the two open the package to find 3 different kinds of dust in silvery red, silvery blue, and silvery gold colors*
Ruby: I've never seen any dust like this before.
Yang: me neither, well, it was free, guess the only way to see what they do is to try them out.
Ruby: are you sure we should just use some of this without even knowing what it does?
Yang: come on sis, when have you ever heard of bad dust?
(Ruby looks down at the dust then back up to her big sister)
Ruby: okay, sure.
A little while later, after setting up some targets.
Ruby: okay, let's see what these can do (loads in some of the blue dust) maybe they're just new versions of some other dust.
Yang: (loads some red dust) yeah, maybe.
*the two girls fire their weapons but the dust just comes out as, well, dust. Then a strange wind blows the red dust onto Ruby and the blue dust onto Yang*
Both girls: *cough* *cough* *cough*
Yang: what the heck? They were duds? *continues coughing*
Ruby: guess someone decided to pull a prank on us.
*Both girls brush off the dust before they both feel a tingle in their spines (presumably from the wind… gk: it's not), Yangs cold Ruby's hot*
Ruby: *very slight deeper voice, just losing a bit of the remaining childish tone to it* (notices a slight pinch from her clothes) what the?
Yang: *nearly unnoticeable higher pitch voice* you okay sis? (Not noticing her clothes start to sag a bit.)
Ruby: something feels off, my uniform feels, tighter.
Yang: what think you're going through another growth… *her voice trails off as she notices ruby is actually close to her eye level, when she knows she's taller than her younger sister* sis you look, ACK!
(it's at this point the dust starts to really take effect)
Ruby begins to grow, shooting up in height passes what her big sister had stood at just moments ago. Unlike her sister her chest did not grow as much...
GK: What? We all know the joke that yang has a huge rack right? I mean did you see the first few seasons?
Anyway, but instead the silver-eyed redhead’s chest was just a cup size smaller than her sister had. Still pushing her bra into uncomfortable territory though, same goes with her backside. Her hair lengthened a bit, more just needs a trim rather than anything else.
Yang on the other hand had some really weird changes about to happen. Of course she lost a bit in height just about being where her sister was in season 2 or 3. And her breasts shrank a small, but noticeable amount. But two things really got to her, her hair shortened as expected which of course made her a little mad (GK: you don't mess with her hair, but I can do it indirectly). But then the two changing girls her a crashing sound, like metal hitting the ground. Yang looked down, seeing the robotic arm she had been using lying on the ground, and in its place, her actual arm, from before it was cut off by Adam, throwing Yang into a swirl of emotions.
GK: PTSD will do that to ya. What? You're giving me a look like I've done something wrong. Do ya think I'm “letting yang off too easy” with this? Well it's realistic, the two are only like, 2 years apart from each other, Yang most likely hadn't grown that much in 2 years, most of this change comes from the dust itself. And if it's about the arm thing, well, the time in this dimension hasn't been two years, yang's arm was cut off less than 2 years ago so it's back. Now, let's just get back to the story.
Ruby: yang you, you look so young! And your arm
Yang: yeah thanks for pointing out the obvious, maybe look at yourself. (She stares at her arm, she knows it's been gone for a while, but it now feels like it never left)
Ruby: oh, sorry, I shouldn't have said anything.
Yang: it's fine, can, we just head back inside for now?
Ruby: um, sure.
After heading back inside they find the closest mirror to see the changes much easier. Luckily no one else saw them, yet.
Ruby: geez, this bigger body makes this feel, (she pulls on her uniform) a little tight.
Yang: *gets one of her spare shirts and a spare bra* here, put these on.
Ruby: oh okay. *she changes out of her too small, (GK: is it a combat skirt? Whatever) uniform and tight bra and puts on yang's clothes* they're a little big, but at least they aren't tight.
Yang: *stares at ruby's bra, before changing and putting it on and then putting back on her jacket* I guess I'm back to your size.
Ruby: so, what happened? Did that dust make us flip ages? Are we stuck like this? *not so panic* does this make me the big sister now? *back to panic* How are we gonna tell the others? What will dad think? What…
Yang: geez sis, you're asking too many questions, we'll just have to tell the others, and hope there's a way to fix this.
So the girls then have to show themselves to their friends and Crow. Here are their reactions.
Crow: what the? *looks at his flask*
Blake: *shocked look, no response*
Jaune: this is, really weird
Nora: what in the world? Swapped sisters? What is this a fan fiction? (Quick glance at 4th wall)
Ren: well, this isn't something I'd thought we'd be seeing.
Oscar: WHAT IN THE WORLD HAPPENED TO YOU TWO!?
Ospin (in Oscar's mind): as long as i remember, I've never seen anything like this before. And oscar can you not shout?
Weiss: how the heck did this happen!?
*a short explanation later*
Ruby: so that's its, weiss, your family is a dust company, do you think they can help us?
Weiss: um, maybe, but, i don't think they'd want to help me.
*After a bit of convincing the group heads off to figure out just what the f@#$ is going on with this strange dust… right after Ruby and Yang get some new clothes*
GK: there, it's done. This took forever to make, all I can say is that I lost motivation to do this. This is still open ended, and there is definitely more to tell, but, I can leave that for another time. See you later, Deviant. Also that's what I'm gonna call you from now on, you said you find your way here through deviantart, so I'll just call you Deviant. Don't expect much from me soon, I'm kinda losing motivation to do this kind of stuff.
