I Think A Lot About How Atsushi Sleeps In Kyouka's Closet. Like. Boy Did You Need A Den. Did You Need

I headcanon that Atsushi’s ability will on occasion partially or fully activate in his sleep so every so often in the middle of the night Kyouka will hear the thump of a huge tiger getting squished into the walls of Atsushi’s closet

[Post-canon AU]

1. I'm so tired

2. My HC is that Atsushi is the more possessive of the two (tiger stuff)

3. I rarely draw kisses

4. I hope it looks good And that's how Yasushi's parents got engaged.

Hc that atsushi's pupils dilate like a cats when he's happy or excited

Or when he's fighting his eyes narrow into little slits and he hisses

And when he's eating or looking at akutagawa his eyes get really big

i want atsushi to have more cat like features. him getting twitchy when he sees birds or squirrels, growling when frustrated and purring softly when content, being very territorial, having a scratchy tongue……… i want him to be more big cat coded

Headcanon that the tiger causes Atsushi to consume more calories/energy doing literally than normal people so his coworkers are always making sure he’s eating enough (especially difficult because growing up in the orphanage taught him to not eat a lot)

Hello

There is not enough BEAST sskk or Kunisig/Kunima ((Kunikida x Sigma)) would you create some for the starving fans

I TOTALLY AGREE WITH YOU ON THE SSKK BEAST OMLLLLLLLL.

BEAST SSKK AND KUNISIG HCs

SSKK Beast Headcanons!!

Aku confessed first but it sounded more of a mission. Atsushi misunderstood and took it way too seriously. When Aku was able to find the correct words, Atsushi nearly imploded from embarrassment.

Atsushi love language is touch and acts of service. He does that thing that cats do and keeps giving Aku dead birds. Aku tells him to stop, it makes people uncomfortable, Atsushi misunderstood and started bringing live birds.

Aku likes to holds hands a lot. Atsushi assumes its because he’s clingey, but it’s actually because his hands are freezing. Atsushi is a little portable heater, and Aku just attaches to him like hair to a balloon.

Atsushi and Aku have no idea how money actually works. They keep trying to pay for shit with things and it gets them in trouble. Atsushi however manages to get things this way, and Aku doesn’t know what he’s doing wrong.

Aku convinces Mori to allow him to take Atsushi to the farmlands. Atsushi keeps threatening to eat the cow if someone tells him to leave Aku’s side. (He won’t, but that is one less cow lol)

Aku sleeps in wierd ass spots, usually up high. Atsushi finds him, and lays on top. Example: if Aku is laying in a tree, Atsushi will lay on top and his limbs will dangle.

Atsushi won’t wear other clothes. Aku has to basically box, cheese, and string him into the shower. Atsushi is more likely to bathe if Aku does it for him. (He can do it on his own, he’s just busy and wants Aku’s attention.)

Atsushi yowls when he’s mad. Only Aku has caught him doing it, and no one believes him when he tells them the White Reaper is more catlike then they think.

After Atsushi rehabilitation at Mori’s orphanage, he can finally work at the agency. He does really well with his coworkers but won’t leave Aku’s side. Fukuzawa ends up giving up, and that's when Atsushi decides that he doesn’t need to be stuck on Aku all the time. Poor Mr. President.

Atsushi does really well with the no-harm rule. If he sees Aku fucking shit up though, he will also cause havoc.

Kunikida X Sigma Headcanons

Note: I have not considered this at all. I took a lot of time to think about how they work together.

How they got together:

Kunikida at first was not interested. He would give Sigma a look and walk off. Sigma just assumed it was because he was an ex-rat. He just focuses on becoming a detective.

Dazai makes Sigma one of his underlings and often works with Atsushi the most. In some cases, Sigma needs to work with Dazai and Kunikida. They don’t work well at first because they keep tripping over each other. They do not communicate well. Kunikida doesn’t get mad at him, though he is a little frustrated it keeps happening. After the case, Sigma offers to get to know each other a little better. Kunikida offers to do some training together to try to find a middle ground so they can work with each other effectively.

They have a good understanding of right and wrong. Sigma opens up about being manipulated and Kunikida promised him he would never. It’s against his ideals. Sigma took that seriously, and had a strong respect for Kunikida.

The training they do actually works really well. Atsushi and Sigma are able to train together. Sigma asks Kunikida more private training to try to catch up and Kunikida obliged. It was all fine till Kunikida pinned him, and they stared at each other. This was the moment they caught feelings, and Ranpo walked in. They try to explain it, but Ranpo thinks it’s funny.

They got really awkward with each other for a bit. Kunikida starts unraveling that Sigma messed up his life plan. Dazai starts picking up that Kunikida is a mess, and starts picking on him. Kunikida blows up and basically has a nervous breakdown. Confessing that he likes someone, he wants to change his ideals and plans to consider the possibility of being in a relationship. Dazai did not do the right thing, and just teased him.

Kunikida keeps running into Sigma. Literally, he can’t stop tripping into him. Sigma accuses him of doing it on purpose, but in all actuality, Kunikida is fated to trample Sigma.

Dazai figures out that those two have this fling after Sigma helped Kunikida up. He sees them staring at each other and was like “:O these bitches gay… GOOD FOR THEM” and now has a twisted obsession to get them together.

Dazai convinces Kunikida that Sigma is in trouble, and Kunikida doesn’t question that Dazai told him to get the closet. Dazai locks them in. Kunikida and Sigma realize this is a trap. Dazai had switched the doorknob, so the lock was on the other side. Sigma pouts that Dazai manipulated him again, and Kunikida comforts him. (He is so gonna beat the shit outta Dazai.) Sigma is the first to confess, and Kunikida nearly blew up. His response was just syllables, and Sigma thought it was cute. Kunikida calms down and returns the confession. They start to plan their first kiss. They end up freaking each other out because they are getting ahead of themselves. It wasn’t till the next day they were released. (Dazai forgot)

Sigma sees Kunikida stress out, and ends up just kissing him there. The nerves start to die down. After the worst of the worst got out of the way, they were making a better effort to talk. Sigma enjoyed the fact that Kunikida was a good man. Sigma didn’t keep up his guard around Kunikida and it started to become aggressively obvious.

They start officially started dating. Regardless of Kunikida’s ideal rule to never date a coworker, he can’t separate from Sigma.

Cute things they do:

Sigma is not a morning person at all. Kunikida wakes up at 6 am every day. He notices Sigma struggles to wake. He gives soft kisses on his brow and makes his coffee.

Sigma often debates Kunikida about topics. They have a lot of things in common, but Sigma thinks Kunikida tends to be self sacrificing. This is often the main topic of their debates.

Kunikida actually really likes Sigma’s hair. He loves to brush it after a bad day. Sigma doesn’t quite understand why Kunikida wants to deal with that mess but loves the attention that he gets from it.

Kunikida taught Sigma to cook. (Something Sigma is embarrassed to admit has no idea how to do). Sigma likes it when Kunikida comes up from behind him and helps him cook that way. He plays dumb, and Kunikida is actually worried he has memory problems.

Kunikida’s love language is acts of service. He loves doing Sigma’s laundry. Sigma assumes it’s because he loves being able to smell him, but Kunikida just really like laundry.

Kunikida loves to guide Sigma with a hand to his back. Sigma will get upset and lift Kunikida’s hand to his back. Kunikida found it weird at first but later found it second nature to touch Sigma’s back when he started to read Sigma’s mood.

Neither are romantic. They actually really suck at it. They try to be romantic but it ends up going really bad and they end up just spending alone time together. They work better just existing together than trying to set up the scene.

Kunikida started using pet names, and Sigma gets flustered. If Sigma starts barking at Atsushi or Dazai, Kunkida will just tell him, “Hey darling, let's not.” And Sigma is tamed. Sigma can’t say anything verbally to get Kunikida to stop lecturing Dazai. He ends up dragging Kunikida to private and kisses him. Kunikida and Sigma would come back kinda scruffed up, and returns to work.

atsushi doesnt like storms becuz all alone in the cage the loud noises scared him but its okay now becuz dazai and ranpo noticed so dazai holds his hand when its storming so the loud noises arent as loud and ranpo gives him candy and yosano bought him noise cancelling headphones and kunikida makes him hot chocolate and fukuzawa gives him a weighted blanket and junichiro calls him every time it says its gonna storm to let him know and kyouka sits by his side so he knows he's not in the cage and akutagawa tried to fight the sky (he was a little tipsy when he first learned)

atsushi with more cat/tiger behaviors but some lesser discussed ones:

he scratches all the doorways of the agency building and his dorm. kunikida scolds him for damaging property for over an hour but while he apologizes he’s strangely uncontrite (at least for atsushi who tends to overapologize) about it

/

a mostly nocturnal sleep schedule feels the most natural to him but since his orphanage’s schedule was (quite literally) beaten into him, he regularly wakes up early, though after a long mission or multiple in a row, he tends to sleep through the day instead.

/

when really frustrated (usually during an argument with akutagawa) he has a tendency to stomp his feet. it tends to break the tension, and atsushi finds its super embarrassing. akutagawa finds it cute

/

he’s constantly fighting the urge to sit on his coworkers desks while they’re working and distract them. same with knocking things off their desks.

/

head bunting!!!! he first starts doing it to kyouka after the end of the guild plot. just does it to her one morning while they’re cooking breakfast without realizing. he’s mortified for a moment until kyouka does it back, equally shy yet earnest about it. slowly he catches himself doing it to the rest of the agency: when kenji gives him a hug after a mission, when yosano buys him something he was looking at during a shopping trip, while sharing lunch with the tanizakis, to ranpo after atsushi solves his first mystery on own, to kunikida and dazai after a dangerous mission. he hasn’t worked himself up to doing it to the president yet (and fukuzawas kind of sad about it). dazai and kunikida are the most flustered by it, kenji and kyouka do it back to him the most.

/

as much as he hates being locked up or confined against his will (and he really hates it), he genuinely loves being in small spaces. he sleeps in the closest for kyoukas privacy but he does geniunely feel comfortable there. sometimes he eats lunch under his desk or in the supply room if he’s feeling stressed. dazai did give him a giant box once to see if he’d sit in it and he totally did.

/

he tends to suck on the corners of blankets and things like his shirts or sweaters when he’s asleep or distracted. dazai used to tease him for it until he read that it was often found cats taken to soon from their mothers. he didn’t really find it funny after that

/

he will just Stare at people. agency members look up from their work and will see him looking directly at them. he usually snaps out of it right after and apologizes but just like slow blinks and winks and closing his eyes, he starts doing it more and more as he gets in tune with his ability.

the bsd ao3 (specifically fics that focus on atsushi) is the only thing that's kept me going these last two years. thank you so much bsd authors.

Your honor that’s his son
