(TW: blood, fighting, and swearing)
Takes place in Middle school (15- Kenny/y-n, Karen 12)
You shake your boots off as you move to adjust your beanie, South Park was in one of its colder days as the season shifted from spring snow to snow snow. Letting out a breath and watching it spiral as you cross over the railroad tracks you missed the small brunette blurr that body slams you back into a snow pile, letting out a loud ‘oof’ sound you allowed the giggling child to sit on your stomach for a moment as you smile. The small brunette one Karen McCormick let her little dimples show as you heft her into your arms and get up. “Hello Kare bear! How are you today?!” You ask as you gently squeeze your self proclaimed sister, your parents passed away a year ago and the McCormicks keep an eye on you as another one of their kids. You shift Karen to your back as you continue walking, she takes up playing with your hair. “I’m doing good, Kenny says you’ve been sad.” She says as she tries to peek into your face, her pigtails tickling your cheeks causing you to laugh softly. “I’m okay, better that I get to spend the day with you.” You smile at the little girl before knocking on the mcCormicks door. The door is opened by an unnaturally red headed lady with a kind smile, “Y/n! Thank you for coming tonight. Kenny is staying with the boys for a school project and unfortunately Stewart and I have a meeting to attend, so we’ll be home late. Feel free to help yourself in the kitchen and if we aren't back by 10 feel free to sleep in Kenny’s room, you know where everything is sweetheart” Carol says before letting you step in and set Karen on the floor. Stewart came past and ruffled your hair before walking out the front door with Carol, turning to Karen you smile and place a hand on her head, “what should we do squirt?” You ask playfully as she bats your hand away. “Let’s go to the park then maybe Stark's pond” she says before racing into her room and coming back with a small backpack you hadn’t seen before, “who got you the pretty backpack?” You ask with an eyebrow raised. Karen smiled brightly and held it up “bubba butters gave me it for my birthday! Oh! And thank you for the hoodie y/n! I’m saving it for a special occasion!” She cheers before putting the backpack on, you slide your wallet and an extra jacket into the bag for you before grabbing her hand and leaving the house. The park was empty when you arrived, you took the backpack for her as she raced off to the play set, for a young teen she loved playgrounds. You scrolled through your phone sending a small update text to Kenny to let him know you guys were ok.
After updating your social you look up only to not see Karen. You panic for a moment and look around wilding for her only to see her pop out of the bathroom and jog her way over. You quickly pull her into a hug, her face smashed into your chest, “please let me know when you wander off next time Kar, scared the shit out of me baby.” you say, calming your heart beat. Karen quickly grabbed your arm and hung on it “I’m sorry y/n! I’ll be more careful!” She claims before you two start walking towards tweak Bros coffee, you open the door, the bell jingling your arrival. “ACK, y/n! How are you tonight!” Tweek calls from behind the counter as you bounce over and pull yourself up to sit on it. “I'm a great tweekers, where’s Craig?” You notice a lack of middle fingers being thrown your way, tweek shakes his head “he’s home, had detention so he didn’t come by to help out” he replies easily calming in your presence, handing you a hot cocoa for Karen, which she happily takes. “Well we just came by to say hey, kens staying over at Cartmans so I’m dragging Karen around.” You say. He nods and waves you guys out as you leave into the darkening day. Rounding the corner from the theater a hand shoots out and yanks you and Karen back into the alleyway, Karen lets out a startled scream before her mouth is covered. “hello Y/n.” A familiar voice calls out from behind the scared girl, your face goes from anger to terror in 3 seconds as you discreetly slip the tracker/alarm from the strap of the backpack pressing it. “Hello Kalma. It’s been a while, come back to finish me off?” You ask, shaking lightly, Kalma lets out a hard biting laugh before throwing Karen off to the side and stalking closer to you “I wish I could finish you off! But you have a use for the plan. Doesn’t mean I can’t hurt you a little” she laughs bitterly before leaping towards Karen, the younger girl crying in terror. You make a split second decision and place your body in front of Karen’s, a sharp stinging pain hits your side as you start to feel a warm spot on your hoodie. “Damn, Kenny’s gonna be pissed I got blood on another of his hoodies” you try to joke out, looking down at Karen. The younger girl can’t tear her eyes away from the injury on your side so you cover her eyes and whisper “run back to tweak bros, tweek can call our angel.” She gives a nod and takes off, allowing you a moment to turn to Kalma. “You just don’t go down huh?” She asks bitterly “just like your parents, maybe you’ll be more challenging then them after all.” you see red at her statement before tackling her onto the ground and swinging your fist into her face landing a couple of blows before she twists the object in your side flipping you onto the wet and dirty pavement. She opens her mouth to say something else when a shout comes from above “I’d step away from the girl if I were you!” Mysterion’s voice is hard to miss and brings a small painful smile to your face as Kalma scoffs. “Whatever I’m done with her.. for now” she laughs before vanishing down the end of the alleyway. Rapid footsteps make their way down the alley as Karen crash’s into you as you grunt. “Let’s get home” you say to her softly, looking into the worried eyes of mysterion.
After getting Karen home and settling into bed, you heave yourself into Kenny’s room and start digging for his first aid kit when the window slides open. You look up and meet the eyes of mysterion, you let out a small painful laugh as you plop on the floor. “Hey Kenny. Guess I lied about nothing happening” you say roughly, Kenny takes his hood and mask off before rushing over and kneeling next to you, “shit y/n how did this happen?” He asks, sliding back into his smooth tone. You yank the hoodie over your head letting him see the injury better “took the knife to keep Karen safe, Kalma went for her first.” You hiss out as he gently pokes around the wound. Kenny shakes his head before pulling out the first aid kit from his closet along with another one of his hoodies, “of course you did, thank you for that but I’m still and you're hurt” he says in a gentle yet stern tone causing you to laugh. Kenny quickly cleans and wraps your side before helping you struggle on his hoodie and pulls you into a light hug, his face burrowed into your hair as he shakes trying to suppress sobs, “when Karen called I thought the worst, I’m so glad you're ok.” He says, before pulling back and looking over your face. You give him a smile and press a light kiss to his cheek, “remember ken, who is responsible for your missing tooth? I think I can handle myself.” You tease him lightly before he helps you to settle into his bed. He threads his fingers lightly through your hair as you start to feel tired from pain and all the energy you used, “y/n, I love you, your family and I will ALWAYS be there to protect you. Please be safe and sleep well bubba” he whispers, pressing a kiss to your forehead and covering you with the blankets before sliding back out of the window to let you rest.
