Undertale AU Sibling Oneshots

Kris x Older! Reader (part 2!)

Part 2 requested by the lovely forbids, @Lua047 & @YourNekoNekoKneecaps!~
(Srry if it didn't tag properly slow data sucks :/ )
(See if you can guess your battle tactic!~)
(Also finished Jacksepticeye's playthrough of Deltarune chap 2!(kinda, I stopped watching after they fixed the fountain) but I might try to get Deltarune (and maybe Undertale too!) for my switch to play in my own time!)

(Random question!: Who's your favorite Deltarune character so far? Mine would be Kris! I adore mysterious characters, but my second favorite would be Susie because I also like tough and baddass characters!)

You sneezed as your open your car door to the freezing cold, tugging your coat and scarf around you tighter. Shutting it behind you, you leaned against your semi-warm car as you waited in front of the school building. You got to come home early, so you decided to wait outside on Kris' last day to surprise them.
You watched as students filed out of the building with the last bell, chattering about winter break and gifts they'd hope they'd get over the holidays. You waved to Noelle, who excitedly waved back before heading on home.
Your mother stepped out soon enough. "Come to surprise Kris, dear?"
"Yep!" You replied, grinning with rosy cheeks from the cold. "I got let out early."
Toriel smiled warmly in return. "That's lovely to hear dear! I'll be heading home, I trust you can bring Kris home?"
"Yeah, of course mom!"
You two departed with a hug, and you watched as she got in her car and drove off.
You waited about half an hour, when everyone had already left, and still no sign of Kris.
You sighed heavily, rolling your neck and hearing it pop. "Alright, Kris, which web did you get tangled in this time?" You huffed, walking into the building.
You didn't bother with any of the classrooms, immediately making your way to the closet. You stuck your hand out, pressing it to the door and shutting your eyes.
"...There you are." You grinned, pushing open the door and leaping into the darkness.
You watched with glee as your form changed, gaining armor adorned in red swirls. Your skin glowed a royal blue, and with a perfectly timed roll, you slid down the sheer cliff and to a stop in the Dark World.
"Woo!" You jumped to your feet, stretching as the adrenaline still skipped through your veins.
Picking up the sword that rested next to you, you slid down the miniature waterfalls, following after Kris.

You found him in quite the pickle, holding off various Dark World monsters. A pink-purple dinosaur monster was a ways away holding off her own volley, and a character all too similar to Asriel was panicking.
Dashing in, you quickly looped your arm around the monster, pulling it with your momentum. It went to turn on you, but quickly backed down at the sight of your red-eyed glare.
"Down." You commanded, rushing off to help the dinosaur, and barked another order as you passed the goat. "Go help Kris!"
You kicked an enemy back the moment your reached the dinosaurs side, and she looked up at you with a mix of confusion and awe.
Together you held them off long enough for them to grow wary and turn tail. Once they were gone, you turned back to join the group, scooping up the scattered shield you lent Kris along the way.
"Are you alright?" You asked, walking no further than three steps before Kris was buried into your stomach, hugging you as tightly as he could. "Hello Kris."
"Kris, who's this?" The little goat asked, adjusting his hat.
"Yeah they look hella badass!" The dinosaur added, grinning up at you.
"I'm one of Kris' older siblings. My name's (Y/n)." You introduced yourself, and soon enough you learned their names were Ralsei and Susie.
It seemed they had simply come back to hang out when they had gotten jumped, and had explained more and more Darkners seemed to have grown hostile.
"Yeah that does sound like a big pickle." You hummed, handing the shield back to Kris. "I'll help you out."
"Really?!" Ralsei said cheerfully, clasping his hands together in glee.
"Hell yeah!" Susie cheered, grabbing Kris and Ralsei before running off ahead. "Keep up (Y/n)!"
"You only end up running into more monsters like that!" You called back, running to keep up with them.
As you traveled with them, you traveled through the various areas, and when you came upon the market you immediately broke off to go see Seam.
"Seam!" You greeted, watching as the cat doll looked up, smiling warmly at your presence.
"(Y/n)! It's been far too long!" He purred, reaching up to hug you around the shoulders.
"You two know each other?" Ralsei piped up, Kris' group having followed you in.
"Oh yes!" Seam hummed, sitting back in his chair as you settled around his small shop, "I do believe (Y/n)'s first time here was around the time the young prince had just been born."
"You were here when Lancer was born?" Ralsei gaped at you, the three of them completely immersed in your story.
"Yep! I'd fallen down here trying to escape some bullies of mine, and the King had me train as a knight for a bit. I almost didn't leave the Dark World that day, it had seemed so much more interesting than being stuck in school with a bunch of bullies."
"What'd made you go back?" Susie asked.
"Mmm, the fact that Kris, Mom and Az would miss me." You replied, reaching out to ruffle Kris' hair.
"(Y/n) made a fine knight, and knew when to back down from their opponents. The day they left is the day I gave them that shield." Seam explained, piping up from organizing a few of his wares.
"Woah! You were a knight?!" Susie exclaimed, grinning a toothy grin. Even Kris was sporting an excited expression.
"Yeah!" You grinned back, looking a bit sheepish, "I could show you some moves later if you want."
"Hell yeah!"
You all continued on, working together to calm the hostile darkner monsters.
"I have a feeling there's another fountain beginning to build somewhere..." Ralsei spoke their thoughts out loud as you all walked.
"Anyway we can tell where it'll be?" Susie asked, scowling as Ralsei shook his head.
"We won't know until it does."
You quickly held out your arm to stop them, seeing a darkner monster up ahead, readying itself for a charge.
"Stay back, I'll handle this." You spoke, straightening your posture. You lifted your hand, palm out, and as your Soul pulsed, flickering in front of your outstretched hand once, you spoke out again with authority in your voice.
"Stop."
The charging darkner slowed to a stop, blinking almost confusedly as it glanced around.
"How'd you do that?!" Ralsei and Susie both gasped, Kris looking up at you in awe.
"I learned a few tricks. But I doubt we'll learn anything else here about that fountain, so let's head back to the surface. Besides, mom's waiting for us at home." You said, turning back to the group.

You, Kris and Susie all woke up in the closet again, and moving quickly, you headed out to your car to see it was nearing late afternoon.
"Susie, you wanna ride with us? It's getting late, and we can drive you home in the morning." You offered, hitting the button on your car fob to unlock it.
"Sounds good, sir knight!" Susie joked, hoping into the backseat of your car alongside Kris.
"Kris I get first slice of moms pie when we get home."
You didn't need to hear him speak to know he'd accepted your challenge, your and Kris' Determination for moms pie combatting one another through the windshield mirror as you began driving away from the school.
