You pounded hard on the dented vending machine, trying desperately to knock loose a can of SOMETHING to drink. This was day 3 of being in this dilapidated city, scrounging for scraps to survive, doing everything to avoid the notice or detection of the various monsters you'd seen around this city. Nervously you looked around, almost expecting the banging noise you just made to attract a vicious beast or one of the other worldly looking denizens of this nightmare world to your location.
As you listened and heard nothing, you sighed in relief, though that did nothing to quench your thirst or fill your belly, wincing as it growled in frustration, hoping the noise of that too wouldn't bring anyone or anything to you.
As you were preparing to walk away however, a feminine giggle resounded from behind you, and your heart nearly stopped in your chest as you paled. It was really close, and they clearly knew you were here. You gulped, turning around expecting the worst only to see...a small, flying woman, a short bobcut of red hair, a pretty face, and all dressed in a tight blue form fitting outfit, that showed her arms and thighs entirely, with matching blue long gloves and legwear. She looked to be the size of a fairy, her entire form wrapped around what looked to be a can of juice.
"Oh wow, it's a human, a real human, still breathing and everything!" she said, her tone excited, a mischievous glint in her eyes as you stared at this girl hovering in front of you with something you desperately want. A drink.
You stood staring in a stupor, before you found your arm snatch out, trying to get the can of soda from this small girl, but she very quickly dodged out of the way before pouting. "Hey now mister, that's rude!" She said right before a gust of wind hit you right in the chest and knocked you on your ass. She had hit you with one of her skills, zan, and you hit the ground hard, groaning.
"This is my hard earned drink, got it human?" She said, hovering down to your face as you almost wanted to cry. "Please...I haven't had anything in days. Just give me a sip..." You begged, the small fairy looking contemplative. "Hmm...I dunno...considering what you are I doubt you'll live long enough for it to be worth it anyway...tell ya what!" The Pixie put the can down on the ground, right near your hand as you heard the tab get pulled and she opened the can of juice before quietly dropping something in it, something you didn't see.
"If you want this juice, then you can have it." She said in a cheery tone, the glint in her eyes never leaving as your hand shot out to grab it. "But before you drink it, I want you to agree to something." The girl said, your hand stopping from chugging the contents, as hard as it was to do, you didn't want to piss her off after she'd just knocked you down.
You looked at her as she giggled once more. "First off, let's get introduced. My name is Pixie. What's yours mister?" She asked before you told her your name.
"Huh...weird name! Well anyway, before you drink that, you need to be aware that if you do, you're gonna be both my buddy and subordinate for the rest of your days, no take backsies!" She said, and it almost made you want to throw the drink away at that moment.
You of course knew that if you did though it was probably inevitable that you'd either starve to death, or get killed by another monster. At least maybe with this girl you had a shot at surviving for a while. Worst case scenario you might even be able to escape from this girl, even though she said 'no take backsies' there had to be some moments she'd leave you alone you figured.
"Okay, um...sure. Deal Pixie!" You said and she giggled.
"Well to seal the deal, why don't you drink up!" She urged and you raised the can to your lips, the sweet taste of a fruit juice hitting the back of your throat, and you blissfully enjoyed taking in this drink. It was a lukewarm but even then it was the best tasting thing you'd ever drank as relief and warmth filled your body.
"Oh...thank you Pixie." You said, before all of a sudden feeling your head rush, an intense warmth from inside feeling like it was spreading to every part of your body as you started to feel intense tingling. "What's...what's happening?" You asked, The Pixie landing and standing on the ground, her hand on her hip as she marveled at her handy work. "You're gonna be my little buddy (y/n), like I said, no take-backsies!" And the world around you shot up as you started to shrink...and shrink...and shrink. Soon you were eye level with Pixie, her face looking delighted as her light pink lips blew you a kiss before you shrank down again, shorter than her, shorter and shorter until...
