need to rub atsushi’s ears and tail till he gets horny and practically humping whatever he’s sitting on

yes oh my gawddddd sometimes it gets tiring for adorable atsushi to hold in the tiger, so when he's relaxing at home with you sometimes he'll let some of his feline features pop out. its usually just his ears and tail and maybe some claws and a fuzzy chest (if you're lucky sometimes some whiskers will appear) - its just much more comfortable like that for him. but atsushi's tiger features are so so sensitive. rub his ears and he's purring so loud you can barely hear the tv or even your own thoughts, but scratching the base of his tail? that's what he goes crazy for. without even thinking atsushi is arching his back and mewling, wiggling his butt to encourage you to scratch harder. it's completely involuntary the way he reacts, and he doesn't even notice the way he starts humping the couch as he begs for more <3

Little tiger 😢😢 eu.. Euuu.. 😭😭😢😢😢 m my baby tiger that I hate

Concept: Orange cat Atsushi

Aka Atsushi’s a regular tiger not a white one and that means he’s got orange cat behaviours.

Tigers don’t purr instead they chuff and as long as he’s not being actively traumatised Atsushi’s always chuffing.

Because he’s happy, happy to be with the Agency.

They find it quite soothing to hear and so whenever someone’s injured or afraid Atsushi will just curl up beside them and chuff.

Touch starved orphan that hates being left alone = clingiest little guy.

It’s something the Agency all has to get used too because they’re not really that affectionate touch wise.

Most of the time Dazai is the target because he will happily indulge him (probably because he’s also clingy as hell.)

If one tries to get away from Atsushi when he’s attached to them he will shriek until they come back.

Kunikida: Atsushi! That’s enough I have a very important meeting to get too.

Atsushi looks up at him all teary eyed.

And then Kunikida leaves carrying a very happy Atsushi with him and glares at anyone to comment.

Atsushi just likes being carried but he’ll always end up upside down and if you try and carry him properly he will jump off you.

Kenji has terrified many a person by happily walking through the streets carrying a giant happy tiger (tiger Atsushi doesn’t realise he’s a giant tiger and still demands to be carried.)

The Agency had rats once and everyone thought Atsushi might do something. No he was just on the sofa, rolled on his back and baking biscuits in the air without a care in the world.

Atsushi is easily started he will jump a foot in the air in fright if the wind blows too hard against the window. He will spend the rest of the day (or rather until he forgets what he was scared off) up on the bookshelves.

He can be bribed down with food though.

Atsushi is rarely ever still, even when he’s asleep or being carried he has to move. Ranpo gave him a fidget toy once and he played with it for 3 hours straight.

The first time Atsushi saw Chuuya floating around he tackled him midair. He then immediately lost interest when Chuuya was on the ground and thus not floating anymore.

Dazai laughed his arse off and filmed the whole thing. And then Chuuya used his ability to get Atsushi off him and then you had Atsushi spinning about like the happiest little guy.

Chuuya: There’s something wrong with this kid.

Dazai: How dare you, Atsushi is a wonderful and amaz- oh shit he’s going blue. Atsushi! Remember to breathe!

Chuuya: How the fuck do you forget how to breathe?!

Dazai: He has a lot going on okay.

Fanfic idea  - Jealous drunken Chuuya x Drunken cat Atsushi

Prompt: As described Atsushi and Chuuya get drunk and comedy ensues

Actual idea- 

So I’m imagining thats its sometime in the future during a cherry blossom viewing.

Everyone is getting drunk and having a great time but cue Atsushi and Chuuya getting drunk.

Turns out a drunken Atsushi acts really silly, like everyone keeps referring to him as a cat and asks him to bring out his tail and ears. Ya know silly stuff but at some point drunken Atsushi just starts acting like complete cat and starts cuddling up to people he likes. You know partially cause he’s drunk and he’s just instinctually scent marking people like an actual cat. 

This all comes to a point where he starts cuddling up to Dazai which triggers the next event.

Which is a jealous drunken Chuuya.

You know in my head Chuuya already found Atsushi to be really cute at the beginning of the night before the tiger ears and tail came out. 

Atusshi is just adorable and Chuuya immediately wants to get to know him more but denies himself since he doesn’t want Dazai to be an ass about it.

Well a few hours later drunken Chuuya gets jealous that the cute weretiger is cuddling up to Dazai. 

Cause ya know Dazai is the worst and in Chuuya’s mind doesn’t deserve to have an adorable creature cuddling up to him and being affectionate. 

So in his drunken jealous wisdom Chuuya thinks its a great idea to go over there and just grab Atsushi and say that Dazai doesn’t deserve to have a cute cat before walking back over to the port mafia side while a confused but still drunk Atsushi just kinda shrugs and continues to act like a cat. 

Just ya know:

Angry drunken Chuuya (clutching Atsushi like a child would a plush toy): “O-oi this cat is mine now! F-fuck off  you Shitty Mackrel!”

Atsushi (who is now slightly confused but unbothered just makes chuffing sounds before cuddling into this new persons neck and nuzzling their cheek like an overly affectionate cat.) 

YESSSS to the"feel strongly, that's what you do when you want to experience the past". atsushi's hallucinations mentioned by fake dazai YAY next month has to be about atsushi's ptsd PLSSS (also, AWWW atsushi's expressions when he's overwhelmed😭 i want to hug him)

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.

Rewrite x3 adventures: oh god why did I start this I am Not Capable

Also rewrite adventures: this paragraph could probably be cut but!! If you weren’t a coward he would’ve licked the injury

Atsushi’s tongue feels too large in his mouth. The tiger in him urges him to dip his head and groom Akutagawa awake, to clean the wound with firm swipes, to press close and share warmth with a too-cold body. Atsushi droops, only to jerk back the second he catches himself, swallowing hard. He is not a tiger, he repeats silently as he carefully straightens Akutagawa’s supine form. Licking would be gross and not helpful and Akutagawa would be mad.

Nekomimi

(The Japanese art concept of giving human characters animal ears and tails is called kemonomimi! And did you know that tigers don’t purr, they chuff?)

216/365: Nekomimi

“Stop laughing.”

“I’m not.”

“You are. It’s in your eyes.”

Ryuu looks away quickly, placing his hand over the lower half of his face. Atsushi sticks his lower lip out.

“Now you’re covering up a smile,” he mutters. Ryuu coughs once, happening a glance back to Atsushi before he quickly turns to face the wall again, closing his eyes.

“How dare you accuse me of such things, Jinko,” he says. Rolling his eyes, Atsushi leans across the futon to swipe Ryuu’s hand from his face. For a split second, he sees the smile on Ryuu’s lips, a rare sight that Atsushi would normally welcome. But in this case, he groans and draws back.

“C’mon, Ryuu, it’s not funny,” he mumbles, crossing his arms over his chest. Ryuu glances at him once before giving a cough that sounds oddly like a snicker.

“Your tail is lashing,” he points out monotonously. Atsushi bristles, an emotion that’s only further emphasized by the fur on his tail sticking out in all directions.

“Imagine if you got hit with that Ability,” he says, round ears pinning back against his head. “Rashoumon would practically have a mind of its own.”

Ryuu coughs again, leaning forward, and Atsushi doesn’t realize until it’s too late that he’s reaching for his ears.

“Yes, but,” Ryuu says, rubbing Atsushi’s velvety fur between his forefinger and thumb, “this is far cuter, I believe.”

Atsushi blushes, and though his fur settles, his tail continues to swipe back and forth. He isn’t sure how long he’ll be stuck like this, with his Ability on the fritz and his ears and tail manifested, but he hopes it ends soon. Asking for Dazai’s help is out of the question; Atsushi wouldn’t hear the end of it for weeks. Months.

“You’re patronizing me,” Atsushi grumbles, shoulders bunched and knees crisscrossed beneath him. But Ryuu takes his fingers from his ear, moving down to the space behind it, scratching there, and Atsushi’s tension seems to suddenly and miraculously leave his body. He relaxes under Ryuu’s touch, closing his eyes, turning into butter in his fingers.

Ryuu abruptly stops, and Atsushi looks up to ask what’s wrong, but Ryuu stares down at him with something bordering on playful in his eyes.

“What was that?” He asks. Atsushi tilts his head, subconsciously cat-like.

“What was what?”

“You made a sound.”

Atsushi frowns. “Did not.”

“You did. You chuffed,” Ryuu says, the tiniest of triumphant smiles on his lips. Atsushi narrows his eyes.

“I did not,” he says again. “I’m not so much of a tiger that I’d-!”

He stops the instant Ryuu begins to scratch beneath his chin. Atsushi closes his eyes again, leaning into Ryuu as if some other force were controlling his body, smiling and definitely chuffing.

“Good kitty,” Ryuu murmurs, kissing the crown of Atsushi’s head as he scratches his chin with both hands.

Atsushi’s tail gives the occasional, satisfied twitch.

Feral Atsushi because he is a weretiger.

Atsushi hates wearing shoes with a vengeance and kicks em off whenever Kunikida isn't looking.

He will argue what's the point anyway when his ability will just break them. It's not like the Orphanage ever let wear shoes anyway so what's the big deal?

When Atsushi runs he will automatically do it on all fours, because it feels natural and he's just faster that way.

He once gave Akutugawa a dead bird as an apology.

Atsushi curls up into a ball when he's asleep. He'll sleep in his futon but sometimes he'll just throw off his blanket and snooze on the floor.

He loves to swim because tiger and is almost as bad as Dazai in that he will just dive into whatever body of water he finds.

Dazai sometimes hops in with him because it's fun and it pisses off Kunikida.

Kenji is more than happy to gift Atsushi with meat he's acquired from family. Atsushi will straight up eat it raw if he's hungry, not even bothering to cook it if Kenji hasn't already.

Atsushi is a lot more alert and focused at night. He likes to take night walks and hunt in the woods.

Atsushi both as a combination of poor socialisation and being part tiger, doesn't understand humans and their etiquette sometimes. He will blurt out that someone is lying.

He will ask and state things very bluntly without beating around the bush what so ever. He was punished and taught to always tell the truth, so this all confuses him.

The only one who gets him in that regard is Ranpo.

When Atsushi gets lost or kidnapped he will roar to try and get the others attention.

Atsushi makes chuffing sounds when he's happy. He takes naps during his breaks, either curled up on the sofa or under his desk.

Atsushi has deemed the Agency as his terrority. He's very protective over everyone in the Agency, especially Kenji and Kyouka.

He had to be held back from biting Fitzgerald because Atsushi sensed bad intentions. Infact the Agency always know if someone's bad news because Atsushi will immediately start growling at em to back the fuck off.

And if that doesn't work Atsushi will than launch himself at them and bite them.

It's why they know Poe and Lucy are cool now because Atsushi just waved at them.

Cut to Ranpo leaving the meeting with Fukuchi after thinking it well. And the moment Atsushi spots Fukuchi he's on all fours hissing

Ranpo:... Well I fucked up.

Nyatsushi Anon! Hello!!! First of all, I'm flattered you like my asks so much!!! And I've talk about Atsushi Cat Concepts, but I just realized- I haven't! Talked! About Tiger Concepts!!! Because baby boy is a TIGER!!! Like, him purring is cute and all but,, Imagine him making tiger noises? Growls? Big old roars??? CHUFFING??? I'm so here for it all ahaha,,, And imagine! Him marking the ADA and his apartment as his spaces with like, scratch marks!!! I'm sorry I'm just Very Enthusiastic aaahhh,,,

DONT SAY SORRY I LOVE THIS SO MUCH BUT Y E S SS BABY BOY IS A TIGER!!! I LOVE EVERY CONCEPT!!!! Y E A A S S S SS

he would definitely do that uwuwu i mean have you heard him yell “AKUTAGAWAAAA” that definitely do be the tiger inside of him yellin 

Atsushi?

Headcanon A:  realistic

He keeps a notebook about all his new experiences living in Yokohama, but rather than focusing on the fighting and bad things, it’s mostly filled with recipes for different foods and drawings of random things he’s seen.

Headcanon B: while it may not be realistic it is hilarious

Since tigers can’t purr, when Atsushi is in his tiger form, he chuffs, and he makes this noise a lot in his sleep in his human form as well when he’s having a good dream.

Headcanon C: heart-crushing and awful, but fun to inflict on friends

Despite all his efforts, he will probably always have days where he feels like he’s useless, and days where he can’t stop thinking negatively.

Headcanon D: unrealistic, but I will disregard canon about it because I reject canon reality and substitute my own.

As a small child, Atsushi only turned into a tiger cub when he transformed.

Do you think Atsushi has trouble eating peanut butter, you know like how a cat's tongue can't grip Peanut butter?

I SAY YES!!

I think Atsushi does a lot of tiger/cat things!

Actually my most favorite headcanon for him, was put forth by @awkward-atsushi who pointed out that tigers don’t meow, they chuff.

So now Atsushi chuffs like a tiger in my mind.

-MI

so much atsushi slander. how do i put into words that his character is so refreshing. that his reactions aren't weak for the situations he was put into and what prep he was given, but endearing to me because he's always trying his best. not in a 'he just messed up and is trying his best sort of way' but in a 'he's experienced so much cruelty that still affects him to this day, but he's still trying his best.' that he hates himself sometimes and can't brute force a solution to the problems he faces. he's just. so realistic.

What do you think would happen if Atsushi tried catnip

Not a question I was expecting to get, but sure! Let's brainstorm.

It would definitely start with confusion—him being cautious when he gets a whiff of something interesting. He smells it before he sees it. But when he finally finds it, he takes it into his hand and sniffs it. Atsushi has no idea what it is, but it smells... interesting.

Then, of course, in a moment, it finally kicks in. He starts to feel relaxed, maybe even a little bit loopy. Meanwhile, Dazai, being who he is, takes full advantage of Atsushi’s state, messing with the younger. Kunikida is a bit concerned but doesn’t insert himself into whatever the heck is happening.

Soon after, the playful side kicks in. He could even start rolling around on the floor, acting more cat-like—on zoomies. He might try to steal Ranpo’s snacks. He better not run into Akutagawa, or he’ll get stabbed. He would definitely knock stuff over, and his ability might go a bit out of control—transforming parts of himself before it fades again. Naomi probably recorded all of this.

After that? Sleepy time. He might curl up somewhere in a sunspot, completely blissed out. Once he snaps out of it, he’s straight-up horrified. He’ll be begging for the videos to be deleted. He won’t be able to handle it.

dazai voice: pspspspsps

Do you like boxes? (I've been watching big cat videos and a lot of them like boxes. Big cats really are just cats, but big.)

much to think about

his day !!

It is I, Nyatsushi Anon, back again because the power of tiger kitty Atsushi is something I don't get to talk about. Anyways, now that I've said my bit on Tiger Atsushi, here's another Nyatsushi Concept- Imagine him grooming the people around him!!! Like, Kyōka rolls out of bed and he, without thinking, tries to "groom" her hair into neatness. Someone has a smudge of dirt on their cheek and he licks it off of them without noticing. Bonus points if he's got a rough tongue!!!

OWOWOWOWO HE GROOMSS!!! okay but kyouka would definitely suddenly start showing up with different hairstyles or naomi and yosani are like “yo how come ur hairs so neat drop the tutorial” and kyouka is like “atsushi. i dont know what he does” and atsushis just like :DDD so he becomes a makeshit hair salon for the Ladies . they love him

and ohoho!! lickin shit off. he wont think it’s a big deal but when dazai returns it and does the same to him he jerks back in shock and is like O-O cause he does N O T expect that (just like how cats dont expect it when u do the same mannerisms as them AGEJEHJSKDS)

It is! The headcanon anon!!! I shall give you four fluffy, somewhat cat!Atsushi headcanons right now to make you smile 💜💜💜 Hopefully these are as cute as I think they are! Regardless of how plausible they may or may not be, though, they do make me smile- Hopefully. They can do that for you, too!

- Much like actual tigers will groom each other and their young, Atsushi will also do this!!! It’s primarily reserved for the baby siblings (IE- Kyōka, Lucy, and Kenji), and it’s done in a more human fashion, but I’ve always imagined that he’ll start idly brushing their hair if it’s messy or it he just doesn’t have anything to do with his hands. He’s surprisingly good at giving them cute hairstyles!!!

- I like to imagine that the ADA has an unspoken rule that you Are Not allowed to move if Atsushi falls asleep on you… Like if someone’s pet falls asleep on your lap, you know?

- He bleps sometimes. I’m sorry, I don’t make the rules. He kitty, he blep.

- Okay so this one might be more funny that fluffy but I feel like the idea of Atsushi chasing a laser pointer is too good to ignore??? Ranpo would absolutely fuck with him using one and it makes me giggle.

Have a nice day, Ray 💜 Make sure to get some rest and sustenance!

Look no I love these and now I'm also stuck thinking about Atsushi being very particular about Dazai's bandages. One starts fraying, they get stained, anything and he's fretting

BUT

he also has the deep urge to bat at them all the time and the struggle is so so real

Lately I’ve been really enamoured with the idea that the tiger is like. a secondary personality in atsushi’s head that he can speak to, and occasionally the living incarnation of gremlin brain

atsushi, grocery shopping: okay so i’ve saved enough coupons to eat this week tiger: fish. eat. consume! atsushi: no, i’m not transforming in the middle of the supermarket so you can go apeshit on the raw fish section. tiger: but….fish prey atsushi: but money can and should be exchanged for goods and services tiger: useless square leaves.

atsushi: smiling is a display of affection, okay? tiger: baring your teeth is a challenge and an invitation to fight or submit atsushi: well, how would you show affection? tiger: slow blink to display trust. rub scent glands against them. chuff. curl around to share warmth. atsushi: that’s– listen I know I had a weird childhood deprived of affection, but I really don’t think that’s how it works. tiger: ….bring prey for them to consume? atsushi: no. i still haven’t been able to look Kunikida in the eyes ever since you left the dead rat on his back porch tiger: was gift. atsushi: he doesn’t eat rats! tiger:…bring mouse? atsushi: you know this would be a lot easier if you didn’t keep suggesting dead animals the rest of the ADA, who’s been watching this one sided exchange go down: 0_0

Have you ever seen one of those videos of Tigers or other big cats playing with a pumpkin that's been filled with meat?

Here's a cute one if you've never seen that before. https://youtu.be/fFOPhelZxPU?si=5jR3eDQg5BU4QBjC

Anyway can you imagine as Atsushi Starts to feel more comfortable and safe around the agency He starts displaying more big cat mannerisms. Because he knows the others won't judge him for it or think he's less human.

Imagine getting him to feel comfortable and safe enough that he starts playing. I think that would be fun.

a/n: THAT’S ADORABLE OMG honestly atsushi deserves to play around every once in a while outside his agency duties given his traumatic childhood :(( i think it’d b so nice seeing him relax a bit and just be the kid he never got to be. here’s some headcanons i think might fit into ur idea !!

atsushi hcs: big cat behavior!

✑ character/s: atsushi nakajima, mentions of other ada members

✑ short desc: just atsushi being the big cat he is.

✑ content includes: general headcanons ; focus is on atsushi ; no warnings, just pure fluff

✑ word count: 1.3k words

i think as much as atsushi may have been portrayed as being on the more timid / wary side in the beginning of the series when he first joined the agency, he was also almost always on high alert / defensive mode a lot — typical cat behavior

after the whole shenanigan with the black lizard breaking into the agency’s main office (and them being thrown out promptly after lol), that’s when his trust in them solidified a little more and he decided then and there that they were the people he could always come back to no matter what

hear me out for this one: although the popular choice for the person able to loosen up his screws a bit more is dazai, i genuinely think that both the tanizaki siblings are one of the most responsible for helping him relax a little around the agency

when both jun’ichiro and naomi aren’t being weird (ahem) or when they aren’t on the job, i’m pretty sure they act the same way all typical teenagers do — they have interests outside of work / school that they spend time with, like to go along with trends, and they socialize a lot with people their age

and because the tanizaki siblings are the closest age-wise to atsushi, i think he learns to act his age around them as well. they probably hang out every once in a while and do normal stuff that don’t involve the use of abilities or crime-solving

hanging out with dazai is a little more different; i don’t want to make their relationship seem shallow because i know there’s more to them than meets the eye, although branching out in this post might make me go off topic, so we’ll just stick to saying that beyond them having a mentor / supervisor and student relationship, dazai seems to be able to bring out a much more honest and open side to atsushi

dazai’s words of encouragement and points of advice allow him to grow from being stuck in a circle of self-pity and learn to slowly move on from the events that traumatized him as a child — that being said, atsushi learns to unfold himself a little more with dazai’s guidance, which in turn helps him become a more honest version of himself around others

outside agency duties, i hc dazai to be the more chaotic of the two, often dragging atsushi into whatever shenanigans he has planned. he probably lures atsushi into playing pranks on kunikida, who very likely finds them irritating at first (schedule issues) but i think kunikida has the heart to let them off easy every now and then given he’s well-aware that they never had the easiest upbringings either. and if he scolds dazai / atsushi, it’s really just because he cares about them

with ranpo, i think atsushi is probably the more mature of the two. i hc that whenever they get paired together for a mission and are sent out of yokohama for that same reason, they often stop by candy stores to bond over buying sweet treats after accomplishing their tasks

yosano comes off as quite strong to atsushi at first, and the whole operation thing probably still scares him to death, but her kindness and care towards everyone including atsushi helps put him at ease. he’s at comfort knowing that someone is there to patch him up as well as the other people he cares about at the end of the day, even if his ability allows him to regenerate his limbs

he learns to become an older sibling figure through both kyouka and kenji. there’s more responsibility taken for them outside their jobs (older brother duties), but the innocence that comes with playing games with them or simply chatting about whatever topic pops up helps him hold onto his own innocence

and then there is fukuzawa — stern as he may appear, i’m sure he genuinely cares for the well-beings of all his employees. his ability says it all: it gives his subordinates all the control and freedom needed to ensure that their abilities are under full command of themselves. from atsushi’s side, there is gratefulness (especially after making peace with his own ability), but from fukuzawa, there is a lot of parental care outside duty (also because atsushi is part cat and fukuzawa likes cats lmao)

that comfort from having peers he can socialize with without the fear of being bullied or messed around with allows him to feel a little more at peace with himself at some point later on, and because he is part-tiger, he eventually ends up becoming more playful around everyone when his feline instincts come out

i like to imagine everyone sees it as a little inside office joke at first when they buy him toys like those cat scratching pillars or the little fishing rods with the feathers at the end, and he gets embarrassed about it initially, but he’s around people who care about him and don’t judge him for what he is, and he figures hey, why the hell not?

so now, it becomes the norm for one person every day to bring a new cat toy for atsushi to play with

it’s kenji who brings the pumpkins to the office (which earns him a few side-eyes of confusion, not to his knowledge), and at first, atsushi doesn’t really know what to do with them until one day after a particularly stressful mission, he finds himself gnawing at the pumpkin to help relieve himself a bit

it’s a strange feeling at first, but being able to sink his teeth into something that (thankfully) isn’t human flesh really helps him relax

sometimes he’ll use his tiger claws to slash at the pumpkins and mess around with the insides if he doesn’t feel like using his teeth

nobody at the agency really says anything about it aside from the occasional joke about it here and there but it’s all light-hearted and they seem to really enjoy watching him be himself around them

there is now a supply of pumpkins specifically for atsushi, and the roof garden above the agency now also has a pumpkin patch (run by kenji and kyouka, of course, and supervised by fukuzawa every now and then) so they don’t run out

remains of the pumpkins aren’t wasted. somehow the rest of the agency members (or at least the ones who know how to cook) find different pumpkin recipes to try and now they have a mini cookbook in the communal kitchen where the main ingredient for every dish is a pumpkin lmao

i’d imagine that if they do celebrate halloween, atsushi’s in charge of gnawing out the insides so the rest of the members (and he himself) can carve their decorations on the pumpkins respectively

when atsushi is sleepy, he’ll rub his face around on the surface he’s laying on or the person nearest to him (kind of like cats in general) and i think that a lot of the other members find it adorable so nobody makes any comments about it when he does that

sometimes dazai will bring one of those laser pens around when he’s bored and when he points it at a wall (or kunikida’s forehead), atsushi instinctively goes up to try and “catch” it lmao

i think he really enjoys playing hide-and-seek with the kids (and ranpo) especially when he’s “it”, primarily because of the feeling of the chase / hunt (which big cats seem to enjoy)

to no one’s surprise, fukuzawa enjoys playing with him a lot when he’s in his big cat form. i feel like he spares a few of the sardines he keeps in his yukata for atsushi as well. he probably carries around one of those fishing rods with a toy fish / feather at the end for atsushi (and atsushi enjoys it anyway lol)

everyone thinks it’s very enjoyable seeing him be himself. even if the whole found family dynamic turns out to not be true in canon, his happiness will still remain their happiness because they’re all still part of an organization who supports each other and are understanding of one another’s upbringings

atsushi with big cat behavior is so cute :>

a/n: i think i enjoyed myself a little too much with these and got carried away LMAO feel free to let me know how i did!

Late night thought about Atsushi. If the orphanage didn't mistreat and starve him, would he have been as muscular as a tiger? Would he also have more tiger instincts and have a stronger connection to Byakko?

I love any Atsushi hc where he has cat-like behavior. It's so adorable to see fanart of him doing the cat rub thing/head butt against other characters, but i would also like to see more tiger specific traits. Like they have "flexible spines" which gives them a wide range of movement compared to other big cats, their salive has antiseptic properties, they love water, and their canines have pressure-sensitive nerves to know where to bite their prey. All of which would be interesting in a fic, i think.

Atushi please answer me if you had catnip would you get high I need to know this is very important information

First off, I'm a tiger, not a housecat, and I'm not sure if catnip works on tigers.

Second of, I have no idea because I've never eaten catnip or any sort of drugs, although one time dazai gave me a coffee so good that I'm pretty sure that's what drugs feel like, haha.

I remember i was asking kunikida why he liked coffee so much because honestly it's so bitter and dazai said he had some really good coffee that could definitely change my mind.

The next day he brought me some homemade coffee at work and it was really minty and i did NOT know coffee could be that good. i felt really hyper and i did even more work than kunikida that afternoon! He acted kinda weird about it though. He's not the competitive type at all so usually he's happy when i do a good job at work. Instead he was too busy because he took dazai to another room and kept shouting at him i couldn't tell you what it was about because at that point i was feeling kinda dizzy. Kunikida came back dragging dazai by the collar a little while later and I think i also saw yosano give dazai some cash when kunikida had let go of him. She looked pissed about it. Kunikida let me go home early when i told him i felt dizzy.

Even if though i did feel pretty light headed after, I still really wanna try that type of coffee again. but dazai said it was made from some super expensive foreign ingredient, at first i didn't really believe him and tried to search online for it, but i couldn't find anything about it and something that tastes that good and gives you that much energy must be hard to find so he's probably telling the truth!

atsushi licks his wounds until someone next to him stops him

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.

Cat!Atsushi spending the day with Akutagawa (hc)

This is based off my “Atsushi w/cat like urges” headcanons (will be linked below). Feel free to take this as platonic or romantic 😉

TW- mild swearing (nothing to bad, just a few mentioned here or there)

It originally started out as a way for the ADA to get at least one moment of peace to do their work without worrying about Atsushi accidentally swating something off the table or out of someone’s hands

It was one of Atsushi’s “bad days” where the cat urges he felt from the Tiger were more violent/prominent and between the broken mugs and near constant head scratches, everyone was starting to get frustrated

Atsushi included

He felt terrible for causing so many problems around the office and always got frustrated when he couldn’t control the urges the Tiger gave him

Of course no one blamed Atsushi, it wasn’t his fault his ability caused him to nap if he sat in the sun to long, or lead him to ignore people completely for no reason

But it was taking Kunikida all his will power to not yell at Atsushi when he swatted at his ponytail like it was a cat toy for the fourth time that morning

Of course Dazai, being the selfless mentor he was, offered an idea

“I have a job for you that should take up most of the day. I’ll even call Akutagawa to help out!”

It was clear as day that Dazai was scheming something, but everyone was to tired to argue.

And it would be good for the truce if the Agency and Mafia worked together more often

So thats what lead to Dazai and Atsushi walking across town to the Port Mafia HQ to steal Akutagawa on his day off

He refused to let Atsushi know where he lived, so they planned to meet at the Port Mafia instead

“Why do I have to be teamed up with him?” Atsushi had whined as they walked through Yokohama

“Because it’ll help the Agency and Mafia get along better!” Dazai had responded with a big smile as he wrapped an arm around Atsushi so he didn’t walk off

‘It’ll help You and Akutagawa get along better’ is what Dazai really meant

Luckily Atsushi’s discourage about having to spend the day with Akutagawa kept him from getting to distracted on the walk over (he only wondered off twice)

When they got there Akutagawa was patiently waiting outside the Port Mafia building, though he also looked less than pleased to be spending his day off with the weretiger

Dazai pretty much just dropped off Atsushi with a “Take care of him, and be careful around cups!” Before walking off

Atsushi and Akutagawa just glared at each other before Atsushi sighed and asked if Akutagawa was hungry

“We can go over the case while we eat, that’s all” Akutagawa didn’t argue, just huffed and started walking down the street

The first thing that Akutagawa learned about the Jinko was that if he didn’t keep a close eye on Atsushi, he would loose him in the heavy crowds of Yokohama

The first time Akutagawa lost Atsushi, the latter was helping a little girl who had gotten separated from her parents. Nothing new

The second time he lost Atsushi, he was found at one of the candy shops in town. “Ranpo-san’s birthday is coming up soon and this is his favourite shop” Atsushi had claimed

They spent much longer than Akutagawa would have liked in the candy store, but Atsushi refused to budge until he got all of Ranpo’s favourites

The third time they got separated, Akutagawa found that Atsushi had somehow been convinced to chase birds in the park with some of the little kids

Akutagawa had no idea how or when that had happened but he was already starting to loose his patience. This was the third time in the half hour since they left that Atsushi had wondered off

Akutagawa had to practically drag Atsushi by the collar to get him to leave, especially when Atsushi tried to get them to stay by giving him the big kitten eyes

It took all Akutagawa’s will power and “hatred” for Atsushi to not sigh and agree to five more minutes of running around

The second thing Akutagawa learned was that Atsushi ate...a lot...

“It’s the tiger” he had said sheepishly after scarfing down his 12th bowl of chazuke within the short time they had been at the restaurant.

Akutagawa just hummed and continued to eat his food. He wasn’t one to judge, Rashomon was the same way.

The third thing Akutagawa learned was to keep anything and everything glass or ceramic away from Atsushi

Atsushi had tried to explain that it was one of his “bad days” but Akutagawa didn’t catch on until half way through their lunch when Atsushi tried to swat the tower of empty bowls off the table

Luckily for them Aku was quick on his feet, using Rashomon to catch the bowls, and finding out it apparently wasn’t uncommon for things to get knocked off the tables according to their waitress

“The tables are pretty small, it happens all the time so don’t worry” she had said while Atsushi began to apologize profusely for the trouble

Needless to say, they took over the neighbouring table to keep their empty dishes on so they didn’t have another incident

The fourth, fifth, and sixth things Akutagawa learned was that Atsushi couldn’t sit in the sun for more then a few minutes without falling asleep, he was clingy, and he was addicted to head scratches

“Jinko, hand me that case file Dazai-san gave you.” Akutagawa had asked only to get no response from Atsushi.

“Jinko? Jinko are you listening to me?” He had asked, looking up to see Atsushi’s head resting in his arms and face towards the window. It was only when Akutagawa saw the sun illuminating his partners face did he realize Atsushi had fallen sleep.

“You have got to be kidding me...” it took Akutagawa two minutes longer than usual to wake Atsushi up. It wasn’t the first time Atsushi has fallen asleep during a mission. But it was usually during late night steak outs not in the middle of the afternoon at a restaurant. In the end Akutagawa had to blow in Atsushi’s face to get him to finally wake up.

“Huh...what’s wrong Akutagawa?” Atsushi had asked as he rubbed the sleep out of his eyes. Akutagawa did not find it cute when Atsushi’s nose scrunched up as he stretched out his arms. He most certainly did not!

“You fell asleep”

“O-oh my gosh! I-I’m so so sorry Akutagawa! The sun makes me really sleepy! I’m sorry!” Atsushi had stuttered out, face red with embarrassment. Akutagawa just shook his head and told Atsushi it was fine.

“But sit over hear so you don’t fall asleep again, idiot”

So there they sat, Atsushi sitting as close to Akutagawa as humanly possible. Like he was borderline sitting in Aku’s lap as they looked over the files

“Jinko must you be so close?”

“Yes, it’ll be easier for both of us to read the files like this”

So there they sat, Atsushi practically in Akutagawa’s lap, his head on the mafioso’s shoulder as they read through the files Dazai gave them.

It wasn’t long before Akutagawa could feel Atsushi staring a hole into his hands. Every time Akutagawa moved his hand to turn a page or cover a cough, Atsushi’s eyes would follow like a hawk

Rather than just ask Atsushi what was wrong, Akutagawa decided to do a little experiment. He had remembered seeing Dazai pat Atsushi’s head a few times in the past, and the weretiger seemed to like it

So without much thought Akutagawa raised his free hand and rested it on Atsushi’s head. Atsushi squeaked a little in surprised confusion before eventually melting into his partners touch

That’s when Akutagawa discovered his favourite thing about Atsushi; thing seven, the jinko purred when he was happy

Though it wasn’t long before Akutagawa learned his least favourite cat trait that Atsushi had

It was getting late and both boys were starting to think Dazai had sent them on a while goose chase (took them long enough)

“I’m starting to think Dazai-san has sent us on a wild goose chase.” Akutagawa huffed out, rubbing his temples with his free hand. The other one was holding three of Atsushi’s shopping bags, apparently they were all gifts for the Agency members.

After a few moments of silence, Akutagawa raised an eyebrow.

“Jinko?”

No response.

“Jinko! Jinko are you listening to me?”

Still no response. Now Akutagawa was starting to get annoyed.

“Jinko you best not have fallen asleep again because I will NOT be carrying you back-“ When Akutagawa finally turned around he was surprised to see Atsushi still following him, and not asleep on a park bench (it had happened earlier, Aku was not happy). Though rather then looking Akutagawa in the face like his partner usually would, Atsushi was staring at his phone.

Okay. Maybe Atsushi just didn’t hear him, the weretiger did have an annoying habit of zoning out during missions when nothing was happening. So Akutagawa stopped and tried again.

“Jinko snap out of whatever trance you’re in. We’re still working remember?”

But rather than Atsushi snapping out of it, stopping in his tracks and apologizing like usual, he just continued walking down the street. It was almost as if he was ignoring Akutagawa.

“Jinko are you ignoring me!? Where are you going!?”

Still no response. Now Akutagawa was getting pissed. No way in hell was he just going to stand by and allow his cat like partner to just ignore him after all the babysitting he had to do! Atsushi had walked off three more times after lunch and Akutagawa did not want to be dragged around another department store.

So Akutagawa stormed over to Atsushi, grabbed his shoulder, spun the weretiger around, and snatched his phone.

“Atsushi look at me damn it!”

That seemed to pull Atsushi out of his daze. ‘Finally!’ Akutagawa thought as Atsushi looked up at him, purple and gold eyes blinking a few times before registering what was happening.

Suddenly Atsushi’s face turned a deep red and his face dropped in horror; Akutagawa had him by the shoulder, Atsushi’s phone in hand, and had actually used his name for once. He messed up and he messed up big.

“A-Akutagawa...I-I-I’m so so so so so s-sorry! Oh, it happened again, and in public this time! I’m so sorry I didn’t mean to, I just kind of zone out and oh my god your probably angry with me now!” Atsushi scrambled out in a mix of embarrassment, guilt, and fear. It was one thing when he accidentally ignored the ADA members...it was another thing to ignore Akutagawa.

Noticing Atsushi’s nervousness, Akutagawa let out a long, drawn out sigh and let go of Atsushi to run his hands over his face. While Akutagawa didn’t appreciate being completely ignored like that, he could tell Atsushi wasn’t doing it on purpose. Honestly, he was starting to think that none of the weird things Atsushi had done today was on purpose.

“It-its fine, just don’t let it happen again”

“Yeah, okay, I’ll try!”

It wasn’t long after that till they realised they had, in fact, been sent on a wild goose chase and neither one was happy about it

“Dazai-san! I can’t believe you would send us out on a fake mission like this! Well, actually I can believe it, but still!” Atsushi had said the moment they entered the ADA office

Dazai, of course, was laying on the couch with a smile on his face that clearly screamed, ‘But you both had a good time didn’t you?’

Despite a few hiccups here and there, Akutagawa and Atsushi had to admit that the day wasn’t all that bad.

They still kicked Dazai off the couch though. They were tired and needed a minute to sit.

It wasn’t long before Atsushi had passed out again, his head laying in Akutagawa’s lap this time.

“Do you want me to move him Akutagawa? It’s getting pretty late?” Dazai had asked when he noticed the silver haired boy had gone quite.

Akutagawa glanced down at his partner; he had covered Atsushi with his jacket so only his face was visible, but even so his face looked the most relaxed it had been all day and he could hear Atsushi’s purring as he combed through his hair. A ghost of a smile tugged at Akutagawa’s lips as he shook his head.

“No, it’s alright. It seems he’s claimed my lap for the time being”

Wow okay, this is my first time doing a set up like this! I hope it turned out good 😅. Like I mentioned earlier this is based off of a mini series on my tiktok (@bigglitchcos) about Atsushi if he had cat urges. Someone had mentioned doing a skit where Shin Soukoku spend the day together, so here’s my take!
