Ya Know, Atsushi Probably Really Struggles With Physical Affection. There’s Probably A Very Few Number

bro got so relaxed during a nap he un-tigered

hc that atsushi finds the nearest soft item and starts kneading it with his hands when stressed because it calms him

My only "pet peeve" about Cat Like-Atsushi stories

I don't know if anyone else cares about it, but I care about it so imma talk about it.

Tigers cannot purr.

Basically Roaring and Purring are exclusive. Cats who can purr can not roar and cats who can roar can not purr. Tigers roar, they do not purr.

Now honestly, it doesn't bother me too much, as purring is adorable and Atsushi being able to purr while human can be explained away by "Oh human vocal cords aren't strong enough to roar, so when he's human he can purr instead", but i would like to see some roaring atsushi fics.

Like, maybe Dazai's teasing goes a little too far one day and he roars to warn Dazai to get out of his face, or Kyouka gets lost in a crowd and he roars to find her out of instinct, or if you wanna get shippy he roars as a way to get Akutagawa's attention.

I guess I just wish Tiger habits were explored more was apposed to him just being compared to a domestic cat.

That's all.

Edit: Unrelated, but you know how Snow Leopards carry their tails around in their mouths? I know tigers don't do it, but I kinda wanna see Atsushi do that. Like his tail pops out when he's nervous and he walks around with it in his mouth. Idk it just sounds cute.

Tigers that are kept in captive can develop repetitive behaviours to cope with stress and such.

Imagining if because he spent his life in captivity, Atsushi developed his own.

Atsushi paces when he's nervous or upset, even when he's tired or injured he'll pace back and fourth.

Atsushi who used to bite the bars of his cage and now ends up chewing on his fingers and clothes.

Atsushi who keeps his nails sharp, just in case he's caught off guard.

Atsushi who has trouble following his instincts, because of how long he spent trying to suppress and hide them.

ada going to zoo but oop they have to put atsushi on a child leash so his predator instincts dont take over

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

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!

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.
