ishimaru's tumblr is some political posts, personal blogging where he writes his schedule and lists his homework, reblogs and he comments on reblogs, and the occasional hot guy thrown in there that he reblogs without comment
Ibuki has "reblog if you're not homophobic" with punk pictures and cute people and fashion and things reblogged without proper sources
mahiru has an aesthetic/photography tumblr with some long rants that she deletes immediately after
asahina just looks in the sports and donuts tags and reblogs exercise tips and makes happy text posts talking about her life
mondo barely uses his tumblr but has some motorcycle/zoku type pics reblogged and ishimaru messages him random shit.
chihiro has some inspiration positivity stuff and also some video games and computer shit
kirigiri is the science side of tumblr. she rarely goes on and reblogs strange shit and creepy stuff sometimes and a lot of masterlist posts and tips/tricks.
so ishimondo headcanon: Ishimaru has a lot of nightmares and wakes up Mondo a lot from like shaking or crying or something and even though he pretends it annoys him, Mondo thinks it's really adorable and holds him and cuddles him and kisses him and makes him feel better until he falls back asleep uvu
sdr2 au where everyone lives and fuyuhiko buys a puppy for peko bc shes sad and fuyuhiko is desperately trying to be the bestest boyfriend and make her happy y
SDR2 SPOILERS YOU'VE BEEN WARNED...pOSSIBLY SAD TOO I'M HAVING FEELINGS HELP I'VE SHIPPED AND I NEED LIFE ALERT... THIS IS REALLY LONG TOO LIKE A FUCKING ESSAY:
I feel like if SOMEHOW Peko could wake up after SDR2 , Kuzuryuu would feel extremely guilty for letting Peko feel any guilt over hurting him during her execution, also for letting her think she was a tool like her entire life. He'd want to just love on her so much and make sure she knew it. Peko would be all love, what is that? (DON'T MAKE A JOKE HERE IF YOU READ THIS NO DON'T) for a while, but Kuzuryuu would show her what love is and how loved she is.
He'd frequently take her on dates, usually to restaurants that served her favorite foods , hers mattered more than his, and he would adapt to her tastes anyway, he'd buy her dolls for her collection (even if that embarrassed her), he'd basically buy her anything she wanted material...but in the end the material things didn't matter to him, that was just one part of making her happy. Nothing made Kuzuryuu more happy than seeing Peko smile then blush and thank him (and possibly give him a kiss or two....) ...or at least until she would say "I love you, Fuyuhiko." to him.While he tried to maintain his tough guy gangster image (which was hard enough with his cute baby face) , Peko would melt his heart more than anyone else ever in his life. He in the end would not care how much this embarrassed him anymore, as long as Peko loved him and realized she was not his tool. He always wanted her to realize she was his lover,and his best friend, before anything else.
I'm pretty sure they'd be Yakuza, eventually tattoos and all. Despite her previous body guard protection of him, they eventually became equals to each other and would protect each other...but Kuzuryuu would put a huge priority on protecting her , as he never wanted to lose her or make her feel like she failed him ever again. If she got hurt, he'd figure some way to care for her , and also take down whoever hurt her. If he got hurt, she'd do the same for him.
He'd likely take less risks as far as being a Yakuza goes but he'd be proud of his lineage to some degree (other than the part where Peko was pushed to be his tool) . They'd essentially be partners in crime, but it'd be the best thing for both of them as that would be what they both truly wanted in the end. Probably the only thing that'd make them leave it all is if they had a family and their family was put at risk (Which seems like a very good and valid reason) .
tl;dr I feel like no matter what, they'd break out of their dysfunctions to become a wonderful couple with a healthy relationship and would be quite adorable basically lol.
I guess this'd be an AU?? but possible spoilers here too I guess? Wedding headcanon though. WELCOME TO I WRITE SAPPY HEADCANONS HELL LOL.
I imagine the day Kuzuryuu and Peko get married everyone from the school is there . Hinata is like Kuzuryuu's best man due to being his sworn brother, Nekomaru and Twogami would be his other groomsmen. Peko decided to make Chiaki her matron of honor (because I so see her with Hinata, it'd just work) Akane and Ibuki would be her other bridesmaids . They wouldn't have a flower girl, much to Hiyoko's disappointment as she wanted to be it anyway because despite her usual lack of care for anyone, she was excited about the possibility of doing something cute and pretty. There'd still be occasional rivalry between Souda and Gundam over Sonia and it occasionally would make them talk during the ceremony, only to be sushed by Sonia .
The wedding would be quite traditional , though Peko would still wear her Shinai on her back even with a wedding dress on (I think she'd wear a simple a-line wedding dress, nothing too fancy but still pretty). Kuzuryuu would wear a much dressier outfit than usual, but still a pinstriped tuxedo , which impressed Peko a lot and made Kuzuryuu blush more than usual because he realized it. I think that Peko would still be taller, but only by like 2 inches now. Even then she'd have to tilt her head down a bit to kiss him and that'd slightly embarrass him but he'd feel like it's entirely worth it. I think he'd probably blush redder than a tomato seeing her for the first time in that dress too. It'd be adorable. EVERYTHING WOULD BE ADORABLE ABOUT THIS I'M JUST SAYIN'.
After the wedding/the reception...I have a feeling they'd both be drinking water (Because Kuzuryuu can't hold his liquor , and Peko would do it too because she wouldn't want to drink either...possibly another reason too ;) if you get what I mean) . I have a feeling that everyone else would drink and Nidai would probably get wasted with Gundam and that'd be an entirely interesting thing. Mikan would fall into a fanservice pose after like 2 drinks. It would be a night full of memories and thanks to Mahiru (this sounds tragic and awkward I'm sorry ) there'd be lots of pictures of the entire thing.
For Kuzuryuu, getting married would signify to her that she's no longer his tool, for Peko this would be something to make her truly realize he was committed to her as a person and she was not a tool.
I think that Kirigiri would be the big spoon , not because she’s taller, but that’s just how it’d be, regardless of anything else with their relationship. Mostly because he’d be glad to be with her.
GOD THAT WAS SAPPY AS HELL AND I’M LIKE ;_; NOW FOR NO RAESON.
