Okay so I was outside getting my cat off a window sill because she's annoying, and right after I got her off a hUGE spider came out of no where and it scared the frick out of me.  And then I thought, "What if I made some sort of headcannon out of this?".  So here ya go.

Hope you enjoy!! ☺️

KuroKen-
Kuroo is desperately afraid of bugs and will crouch down and hide behind Kenma until it is dead.

Daisuga-
While Suga is afraid of big bugs like those gigantinormus (yes I just made up a word) cockroaches, both don't mind little spiders and stuff.  I mean, Suga and Daichi have ten kids to care for they can't be afraid of these things.

IwaOi-
Oikawa fricking jumps into Iwazumi's arms until its dead (look at the picture I found at the top, credits to the original artist!!)

Tsukkiyama-
Whenever Yams sees a bug (especially a spider) he runs into the next room and has a freaking heart attack until Tsukishima kills it (honestly same)

YakuLev(idk the ship name)-
Yaku is surprisingly scared of bugs, and so is Lev so they just cower in fear together.

KageHina-
Yeaaaaaah Hinata hates bugs because their scary.
Kageyama hates them too, but because they make Hinata scream and gives him a headache.

BokuAka-
Akaashi is actually very scared of bugs, and Bokuto loves them.  Ever since he was a kid, Bokuto tried to catch them and then set them free.
