You blink as you're lead into the large room, it was decorated in various Halloween themed ornaments and decorations. 

       "Finally! You're here! Ready to see everyone's costumes?" Tendo chimes, bounding over to give you a cheerful hug.

       "Wait. Shouldn't ___ get on a costume?" Daichi comments.

       "Oh! Dress up as an owl with me Babe! Couples costume!" Bokuto gushes hugging you happily.

       "No. ___ should dress up as an angel!" Oikawa gasps.

       "A fox!" Atsumu speaks up.

       "Onigiri!" Osamu shouts. Everyone pauses to blink at him.

       "No, that won't do ___ already looks tasty." Oikawa shakes his head making you blush.

       "The hell did you just say?" Daishou huffs, stepping beside you. "And you're all wrong a serpent ruler is way more suiting." Daishou sends you a wink. 

        "Oi! You get lost! You weren't even supposed to be a love interest!" Atsumu points.

        "Shhh Tsumu. The wall…." Osamu whispers.

        "Yeah. I was even supposed to be a bad guy. Glad that changed." Daishou smiles.

        "Make them stop." Sugawara breathes.

        "Could you please stick to the script." Kita tells them. 

        "... Anyway. How about you dress up as a cute little devil with me?" Tendo murmurs, tipping your chin. 

       "Nope. We should put ___ in a hazard suit." Kiyoomi pulls you back. "Since all of you are so determined to put germs on 'em." He adds as you look at him and stiffen.

       "What kinda costume is that!?" Astumu gasps at him. 

       "Plague doctor." Kiyoomi answers.

       "... Scary…" Osamu mutters.

       "Wait. We're not putting ___ in some stuffy hazard suit." Iwaizumi speaks up.

       "Yeah! Halloween is supposed to be when you can dress sexy!" Rakurai chimes, making them freeze.

        "Relax lads. This is an extra. We can join in on the festivities too." A reaper rumbles.

       "Really Death? A reaper?" Atsumu huffs.

       "I'm kinda concerned now. You okay Kobalt?" Tendo blinks.

      "He's wearing the skull mask to hide his smile." Rakurai assures. "Apparently we're quite popular villains~" 

         "And there goes the wall again…" Daichi sighs.

        "Awww is Death embarrassed?" Tendo teases.

         "Sh-Shut it lad!" The reaper snaps before shifting and looking down. "I-I just ain't used to it. I ain't done nothing for it…"

          "Aww…" You chuckle going over and hugging him. "You evil marshmallow."

        "... It was sweet til ya said that. Now get off me." He grumbles. 

       "Alright! Let's all go dress up too!" Tendo chimes heading off. 

       "Come on ___! Let's go." Nishinoya tugs your hand toward the changing rooms, giving a grin. 

        "What are you dressing as Noya?" You ask him.

        "Me? I'm going to be a werewolf. You decide on yours yet?" He adds.

        "Mmm not yet." You admit. 

        "I'm sure you'll find something that suits you." He rumbles. He then tilts his head and looks to the side briefly. "So. Wanna go on a date with me sometime?"

       "Hm? You want to?" You blink.

       "Yeah. But it's up to you." He smiles. 

       You go into a changing room, deciding on a devil costume (thanks poll) before heading out to the halloween party to see everyone's costumes. 

        The twins decided on The Shining twins gag costume, making you and a few others laugh. "Told ya they would laugh, Samu." Atsumu beams.

        "... I hate you…" Osamu frowns. 

        Daishou had decided on a villain get up, sending you a wink and tongue flick.

        "___! You're a sexy devil!" Mika giggles, greeting you in a kitten costume.

       "Oh god you got more adorable…" You breathe.

       "Hehe look at Noya. He picked a cop costume." She points.

       "How adorably suiting." You hum as he comes over. "I thought you were going for werewolf though?"

       "Last minute decision. You're a cute devil." He beams. "Ryuu went with zombie." He points.

      "Asahi's supposed to be Sam from Supernatural but he's hiding in the corner." Ryuu murmurs to you guys, pointing. 

      "I'll get him." Noya says going over.

      "Sugawara's a vampire." Mika gasps.

      "Aw he looks adorable." You nod. 

      "___! You picked a devil! That makes me so happy?" Tendo chimes hugging you from behind happily. You blink and turn to him, blinking at his costume. His rigid horns were different sizes, skin purplish with black smudges here and there, his red eyes glow slightly.

      "Oi! No fair! Why do you get the realistic costume!?" Atsumu gasps.

      "Mmm… Cause I'm the writer's favorite?" He puts his hands behind his and leaning to the side.

      "Here we go again." Oikawa steps beside you dressed like a prince.

      "Bullshit! I got a story for me too!" Atsumu objects.

      "Mine's cooler." Tendo smirks.

      "If I may interject. Burst was originally supposed to be about me." Kiyoomi states.

      "And it was supposed to be ten parts." Tendo adds. "Things just didn't work out that way."

      "What a travesty…" Iwaizumi mutters, rubbing behind a werewolf ear that he wore. 

      "Alright. The next one to break the wall gets shanked." Akaashi warns wearing a prisoner's jumper and broken handcuffs.

      "We're sorry." They respond.

      "Thanks Akaashi." Kita hums wearing a fox God costume.

      "Both of you look amazing." You gasp making them smile. 

      "You do too." Akaashi winks.

      "Can we get this started already, I want to sleep." Suna hums hugging a pillow wearing old time pajamas.

      "I want to bob for apples!" Bokuto beams, wearing a Batman costume. 

      "Come on Kenma, the party's about to begin." Kuroo rumbles leading Kenma in. Kuroo had an Egyptian pharaoh costume. Kenma wearing a cat costume.

       "Cat comrade!" Mika bounds over to him, surprising the blond. 

       "I'm a sun!" Hinata rushes by, knocking over a ghoul Kageyama. 

       "Boke! Hinata boke!" 

       "I will bob the most apples." Levi declares wearing a spiderman suit.

       "Hey ___. I brought some sweets for you." Yaku hums coming over and offering you a pumpkin bucket. He gives a fanged smile.

       "Awe you're so sweet Yaku." 

       "Party time!" Oikawa turns up the creepy party music and everyone starts to mingle. 

       Ushijima decided to dress as Zeus, carrying around a cardboard lightning bolt which he would occasionally use to tap people on the shoulder and play innocent.

      Tendo hums, often pulling you in to dance with him. Kiyoomi stayed in the corner for most of the party.  

     "Having fun?" A hum sounds near your ear, making you jump and look over to find a girl in a janitor outfit, leaning on a broom.

     "Ah… Yes?" You blink, tilting your head. 

     "Good. You should tell them it's time to leave soon. Something is coming." She smiles.

      "Ah. Okay. Who are you…?" 

      "We'll meet soon enough… Maybe." She peers about as the lights start to flicker. "Happy Halloween." She hums as you glance at the lights. 

       "Happy Hallo-" You look back over to find her gone.

      "Hm? Who are you talking to?" Kiyoko asks, sporting an angel costume. 

      "Ah… I…" The lights go out and the building shudders. Asahi cries out, clinging to you blindly.

      "Calm down. I'm sure it's nothing." Nishinoya chuckles fearlessly. When the lights come back on you looking around in confusion. Asahi squeaks out with a point making you look up at the wall near the ceiling. A fleshy grey figure sits on the wall, mouth opening up as rows of teeth show themselves. 

       "What the hell is that!?" Atsumu gasps. 

       "We need to leave!" You gasp to them.

       "Exit's open!" Kiyoomi shouts, already at the doors. You swiftly push Asahi towards the door as the others rush out. You're the last out as you make sure the others were out. 

        Stopping to close the door when the creature leaps at you. "Shit." But something stabs through the side of it's head, stopping it and slinging it away. 

        "Don't worry. This isn't your story." The girl from earlier puts a hand on the door knob, sending you a smile. "See you later." She hums before closing the door as a monstrous howl sounds from the building.

        Daishou and Tendo warily pull you back. "So…. How about we finish the night with trick or treat?" Kuroo hums. 

        "Whoever gets the most candy gets to have ___ sleep in their room!" Mika calls. 

        "Like hell I'm losing that one!" Iwaizumi gasps as the others suddenly take off running for a neighborhood.

        "Eh?" You blink back "Wait! What if I win!?" You call chasing after them. Tendo and Kiyoomi linger behind.

        "Think I'll just go to the store and buy a few bags." Tendo hums.

        "I'll go with you. This mask is stuffy without rushing about." Kiyoomi breathes, removing the plague mask as they start walking.

        "By the way did you see that awesome raptor costume?" 

        "Yeah that was cool. The s'mores that hung out next to him made me hungry though…"

        "We should bring food back to the dorm or they're going to eat candy all night and get sick." 

        "They better not. I'll lock them all out… Except for ___."

        "Of course. Of course. That devil costume looked really good though."

        "It did. Your costume is nice too."

        "Thank you. But yours was way scarier."

        "... Think I could scare Atsumu?"

        "I think you could torment him actually."

        "... Even better. I think it'll be worth losing a few nights of sleep."

        "Oh! Could I be your cameraman?"

        "Sounds like a partnership."
