Another Party

Y/Ns p.o.v

NI stared at the creepy child. She glitched, turning all her features opposite colors, then another glitch would occur, and she was normal. Chara extended her hand. I didn't take it. "Well? My arms getting tired, just shake my hand. It's polite." They reassured. I narrowed my eyes at them, "Polite, huh? Aren't you the one who rammed me in the side and knocked me out?" I question. Chara obtains an 'Oh' face.
"Uh, yes, sorry, about that. I was so desperate for a host, I may have gotten a little carried away." They said, rubbing the back of their neck.
"Host?" I inquire.
"I am unfortunately a glitched ghost. I need a host if I am to keep up a physical appearance." She said, bringing her hand back to her side.
I narrowed my eyes at her once more, "What do you need a physical body for?" I ask, almost scared of her answer.
"Well, I used to be part of an AU, in which that boyfriend of yours originates from." I blushed, "Killer is NOT my b-boyfriend!" I say with an embarrassing stutter.
Chara giggles, "I'm part of your mind, I can hear and understand every thought that comes to your mind. You wish you had a relationship with him because your lonely!~" Chara sings.
I run up to her, and get close to her face, restraining myself from stretching her adorably creepy little cheeks with my fists. She gives me an amused look, "What a short temper." She observes. "No, I-I-! Aagghh...! He probably doesn't return those feelings! Ugh, Why are you so annoying?!"
She laughs, "Because I have experience with sibling fights." She chirps teasingly.
Her expression changed, teasing and smug, "You should wake up, you're boyfriend is super worried about you!~" I clench my temples like Nightmare and groaned. Everything turned white, and then dark. I opened my eyes and see Killer, Error, and Color looming above me. I squint from the sudden brightness of the Anti-void.
"Hey, I think she's waking up." Error mumbled.
I hear a sigh of relief, and sit up, groaning. "H-how long was I out?" I say stretching, earning a satisfying popping sensation from my back. Color looks around, "Thirty minutes or so." He says.
I look at Killer, who's looking curiously at me. "What?" I ask. "Your face is beet red, are you okay? Did Chara hurt you? What happened?" He interrogates. I blush a little more, and realize I could feel the warm sensation of blush on my cheeks. I shrug it off, trying to keep cool, "She's annoying, but pretty nice. I don't think she wants to... try anything."
I just remembered that I didn't let her finish her explanation of why she needed a physical form. "Well shit. I didn't let her finish her sentence..." I mumble. Killer looked around worriedly, "If she says or does anything suspicious, please tell me." He finishes. I nod, "Okay, though, before assuming things, I'm going to try and talk with her and see what she wants." I say. Killer nods.

*awkward silence*

"So, uh, I'm just asking now, to break the ice, but do you guys want to go to  another party..? Its today." Color asks cautiously.
"Sure!" I say.
"No." Error protests obstinately.
"Long as Nightmare gives the okay." Killer replies.
Color smiles, "Meet me here in 3 hours." Color says cheerily.
"Wait, can't we just meet up on the ground? Why in my place?" Error asks, obviously irritated. "Because, I'm too tired to set a new location. See ya later." Color says dismissively. Error grunts, and continues stitching a worn jacket. I didn't know he could sew. He seemed to be trying to hide it by turning his shoulder to us. I guessed that everyone here had their own little quirks. Like, my dog is weird, and likes to chase her tail, while I have friends, who like to destroy universes and level cities! ((LEGO Ningago movie reference, sorry not sorry XD))

—TOm SkiPs! BrouGht to You Boi TEM Flakez!—

I decided that I would just wear my f/c hoodie with a pair of s/f/c jeans. I >insert hair style here< and listened to music for the next two hours, alone in killers room, sitting on the floor, in the corner. Petting Lilith, who was trying to bite a peice Unrecognized Flying Food out of the self sustaining tornado of trash. 

You could be doing anything at this moment. Literally, anything. And you listen to trashy depressing songs like this? Seriously. Chara says.

Shush. Maybe you could listen to. I bet you can relate. I say back to her.

Chara huffs, and stays quiet.

....

Can you go get some chocolate? Chara asks. I roll my eyes, and get up, heading towards the kitchen. I opened the fridge, and find a Brand Name chocolate bar. I go back to killers room.

So, how're you going to eat it? I ask.

Let yourself go, and let me take control.

Eeeeehhhh, I don't wanna sound rude.. but, uh, I don't trust you all that much. I protest.

Please? I promise I won't try anything! Chara begs.

I let out an exaggerated huff, and let Chara take control. I was sent back to my mind, and watched as Chara ate the chocolate quietly. She seemed content, when she had a weird, bright red smile. I panicked as she reached for the bag, which held my gun. Chara snatched her hand back, and shook her head, rubbing her face. No. That's the past. You're a better person now... I heard her mumbling. She was so tempted to kill, but she was so desperate for a physical form and to better herself, she shoved all these thoughts of murder and death to the back of our mind.

Take back control. I'm done... I can't handle it.... yet. She said.

I drifted out of my mind, and switched places with Chara. I thought of something. "Why can't you just posses something, like an inanimate body, like a puppet or a robot?" I ask aloud. I could feel Chara shaking her head. No, I can't. I was stuck in the void for so long, I could only get out if I bonded with another beings SOUL. If I tried to get out, in a puppet, I would be forced out, and blasted right back into the void. Chara said. "So I'm stuck with you?" I ask. Yup. She replied.

"Hey, y/n, we're leaving!" I could hear Color shouting from the front door. "Get out of my house." I hear Nightmare insisting. Those two don't seem get along well. Chara mumbled. I didn't notice. I say sarcastically.

I quickly walk down the hallway, and wave by to Nightmare, who needed to "Blow off some steam" in another AU.

"Who's party is it this time?" I ask Color, who was opening a porthole.

"I think its at FlowerFells place." Color replies.

"Is he and Fell the same guy?" I ask.

((I am truly sorry for making y/n ask this question *i cri thinking of how Frisk died*))

"Uh, no. He's part of an AU where Frisk got some sorta sickness, got a new flower after every reset they did. After so many resets, the flowers completely enveloped them, and they permanently died. 

.....

Buts that's just the gameplay! FlowerFell is kinda disturbed every time he gets to see his girlfriend die, but when the player leaves, they see each other again. It's kinda depressing." Color explained. "That is depressing." I say thoughtfully. 

It's all just a game.

Chara said, seeming angry. But anyone could hear the sorrow in her voice.

Sorry I haven't updated in, like, 6 days.... school is frustrating. And I don't have a tablet at my dads house because he does not support me going on apps that have online chats.... huh.

Welp, I hope this chapter wasn't too* disappointing.
