Silly Bsd Stuff I Would Totally Write About If I Had The Ability To Put Two Sentences Together:

dazai voice: pspspspsps

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

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.

fukuzawa, seeing atsushi approach: atsushi, is something wrong?

atsushi, pulling out a squawking chicken from his bag:

fukuzawa:

atsushi:

fukuzawa, misty eyed: thank you for the present atsushi. i appreciate it.

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.

what if genuinely the only thing i want to do is read/watch/JUST EVEN LOOK at atsushi nakajima. what if atsushi nakajima is the only person i have ever felt attracted to. what if atsushi nakajima is the best part of my life. i wish it was acceptable to talk about atsushi nakajima in public.

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)

Anyone who allies with the agency has to go through the Atsushi test.

....

Ranpo realising he fucked up going to that meeting with Fukuchi without glasses and alone.

Because the moment Atsushi sees Fukuchi, he's infront of Ranpo hissing with his claws out.

....

Poe: Are you sure it's alright for me to be here?

Ranpo: already knows but looks at Atsushi.

Atsushi: smiles and waves at Poe from his desk.

Ranpo: Yup.

....

If Atsushi doesn't trust you than you are bad news.

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.
