Beast Ranatsu Has A Lot Of Angst, But Ranpo Slowly Gains Atsushi's Trust And Atsushi Ranpo's. Forehead

thought this as i was getting ready to sleep last night

atsushi who starts getting super clingy -- all hugs and cuddles, more than normal

atsushi rubbing his cheek against his friends'

atsushi giving his sweaters to his friends, or gloves or scarves or other such things

atsushi taking their clothes and wearing them and giving them back

the ada confused as hell, finally going to ranpo like "is atsushi dying???"

and ranpo is like "isn't it obvious"

and the ada is like "no" unaware that atsushi is scratching/sharpening his nails at the entrance

and ranpo is like "its the time of year we get a lot of cats in the neighborhood. he's marking his territory"

fukuzawa is delighted at being shown affection by his cat son but heartbroken that his cat son is trying to make sure no other cat comes

everyone else is mostly just amused

Fun fact: A tigers mating ritual last about six days, this consists of them walking around each other vocalizing softly Atsushi just walking around Akutagawa, humming softly: Akutagawa: What are you doing? Atsushi, still walking and humming: Nothing, nothing at all

Headcanon that the reason why Atsushi’s eyes are purple and yellow is because the yellow part of his eyes is his ability. He was born with bad eyesight and couldn’t see shit so the tiger manifested itself in Atsushi’s eyes to fix his eyesight but now he’s also colorblind.

And then for Atsushi’s first month and a half of working at the agency every time Dazai makes direct skin to skin contact with Atsushi his vision gets 10x worse. And Atsushi’s too scared to point it out at first but eventually he’s like “hey guys every time Dazai touches me I can’t see and also I start seeing new colors what’s wrong with me”

Eventually they all figure it out and get Atsushi a pair of glasses so that he can turn off his ability every once and awhile, Atsushi also ends up learning how to drive because Kunikida and Yosano can’t just be the agency’s chauffeurs and even though he can only drive if he turns off his ability and puts on his glasses it’s still really funny to say that a colorblind teenager can drive better than 90 percent of the agency.

Finally complete

Your honor that’s his son

Atsushi with more non-human features. Atsushi with reflective eyes that creep out (some of) the ADA. Atsushi with pupils that contract into slits like a cat's when the area is bright. Atsushi with small fangs, canines sharper than a normal persons. Atsushi with heightened senses, who picks up on small details that even Ranpo can't. Atsushi who has naturally more animalistic behaviors and movements. Atsushi who shows affection in strange ways, like headbutting or slow blinking. Atsushi who's ability is wholly a part of him, ingrained in his very being.

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
