Halloween Special 2021

Karasuno Head cannons: 

- they snuck onto campus (after they all went trick-or-treating) and used the gym to have a giant sleepover and they stayed up watching horror movies 

-Hinata, Tanaka, and Nishinoya went as the three kids from The Nightmare Before Christmas 

-Kageyama was a pizza because it was the only costume he could find at the last minute  

-Asahi and Kiyoko went as spies, and Tanaka and Nishinoya got very jealous 

-Tsukishima and Yamaguchi went in Minecraft animal onesies, using the excuse that they were the most comfortable option to escape teasing 

-Daichi went as a werewolf, and everyone was too scared to ask how the tail stayed in place when they couldn't find any elastic bands on the outside of his costume. (Daichi purposely hid the elastic under his clothes to see if anyone would say anything to him) 

-Suga and Yachi went as Zombie cheerleaders cause Yachi was to scared to do the costume alone 

-Ennoshita, Kinoshita, and Narita went as vampires and they spent the night trying to bite everyone. 

-Ukai gave out candy with Takeda, and they were wearing skeleton costumes. When the team saw them, Suga had to physically bite back his question about them 'boning' 

Aoba Johsai  Head cannons: 

- They threw a "monster mash" and almost the whole school showed up 

- The third years went as mummies (Hanamaki picked the costume this year) 

- Yahaba and Watari cosplayed as video game characters 

- Kyotani went as Ghostface , and abused the fact that no-one knew it was him under the mask to scare Oikawa and Yahaba relentlessly. He got punched by Iwaizumi when Kyotani tried to scare him, so he figured the third year was un-scare able, and gained even more respect for Iwaizumi 

- Kindaichi went as a priest while Kunimi threw on a pair of fake cat ears and said 'that's good enough' 

- Oikawa got drunk and mistook Matsukawa for Iwaizumi and started getting emotional about how Iwaizumi had always been there for him, and Iwaizumi was right behind him watching as a drunk Matsukawa tried calming down a drunk Oikawa 

- They got in trouble for drinking with their coach, and they had to do extra laps hungover. (Kunimi threw up and got out of them, and Kindaichi swore whenever the coach wasn't looking that Kunimi was smirking) 

Nekoma Head cannon: 

- They got together to spend the night in the woods and played games like hide and seek after telling scary stories 

- They dressed up for school and Kuroo cosplayed for Kenma, Yaku and Lev went as Luigi and Mario, Yamamoto and Fukunaga went as robots, Kai went as a plague doctor, and Inuoka went in a dog onesie. 

- Lev wacked his head on every branch possible and lost every round of hide and seek 

- Kenma won most rounds with Fukunaga in second 

- When Kuroo was the seeker he fell down a hill and then found Yaku on accident 

- Inuoka was to scared to be alone so he followed Yamamoto for the night

Shiratorizawa head cannons: 

- They got candy from the corner store and watched scary movies instead of going out 

- Tendo got a spooky mask and spent the day going  around and scaring people. 

- Goshiki got super scared and teared up when Tendo scared him 

- Ushijima was flinched and reached out a hand to keep Tendo away from him when Tendo scared him, and Tendo burst out laughing at the confused look on his face 

- Shirabu kept jumping at all of the cheap jump scares 

- The last movie they watched was "Train to Busan" and they all cried, Ushijima only shed a few tears but they were there nonetheless 

- Semi kept stealing all of their Hershey bars while Goshiki took all of the sour patch kids 

Inarizaki Head cannons: 

- They all go trick or treating separately to see who can get the most candy and Kita is the judge 

- Every year without failing, Atsumu and Osamu do some kind of twin costume cause they've figured out people give more candy to them this way 

- Suna is super lazy and just throws on some animal ears and calls it a day, he spends the evening scaring little kids and giving out candy with his family 

- Aran wins the candy gathering contest most of the time because he dresses up in matching costumes with his baby sibling and old lady's love him 

- After they've decided the winner for that year, they switch out candy that they don't like and Atsumu always ends up with a pile of tootsie rolls cause he's the only one who likes them 

- Osamu gets a lot of the hard candies like lolipops 

- Suna gets most of the candy bars 

- Aran gets the evenest mix of things, but he shares his stash with Kita occasionally 

- Kita doesn't really dress up unless asked to, so the one childhood costume he has was from when his grandma asked him to dress up for her 

Fukurodani Head cannons: 

- As a school fundraiser the team spent Halloween doing a haunted house walk 

-Akaashi was dressed up like a doll and was so still most people thought he was just decoration but then had their minds swiftly changed after he chased them effortlessly into the next section 

-Bokuto got to be a mad-scientist with a fake chainsaw and he has so happy and emotionally connected to the fake chainsaw he gave it googly eyes and put it up in his room 

- Konoha worked the front desk, taking in money and talking to guests 

- Komi got to jump out at people and he enjoyed it way to much 

- Washio was a shadow person and spent the night running up and down the entire path, following and unnerving people 

- When they were finished they went out for some ice cream 

Date Tech Head cannons: 

- They trick or treated for a while, but then messed around at a local park for the rest of the night 

- Aone went as Frankenstein while Futakuchi went as Frankenstein's maker 

- Kogenagawa went as the yellow angry bird and it was hilarious watching him trying to pick up his phone when he could barely bend over because the costume was so big on him ( it was one of those inflatable ones) 

Others: 

- Daisho and Mika went to a Halloween party in a couples costume, but it wasn't cringy it was one of the cute ones 

- Terushima went as sexy magician and got a wedgie from the tight underwear 

- Sakusa spent the night watching scary movies at his house, annoyingly pausing every five minutes to answer the door and give out candy
