Wing AU? Saru with dark, slim, beautiful wings. The Kings have the biggest, strongest wings. I imagine Munakata with dark wings with blue flame coming from the edges, and Mikoto has wings of fire. Nagare's wings are white, like Anna's, but they crackle with green electricity. Yata's wings look like bright orange fire and he loves to wrap Fushimi up in them~ Thoughts?
I’m imagining that say in this AU everyone is born with small white wings that then grow into something else as they get older and people are judged on the quality and size of their wings, like the most successful and talented people tend to have really huge wing spans and super impressive wings – and only those with larger wings can actually fly too so there’s like this unspoken caste system that tends to look down more on people whose wings are considered too small or deformed somehow. Niki probably has these terrible hellfire wings, all red feathers tinged in black and the feathers are really jagged and sharp looking but even so he can fly a little with them. When Fushimi’s little Niki plucks a bunch of feathers from his little baby white wings, leaving a bunch of bald spots where the feathers haven’t grown back, and due to the combination of stress and neglect some of Fushimi’s other feathers fall out entirely. By the time he reaches middle school his ‘true’ wings have started to come in but it’s no comfort, his wings are this really dark murky black (and having black wings is considered a bad sign, like if your pure white wings have gone black there must be something wrong with you) and there are spots where the feathers are mottled in white or red, places where his feathers originally fell out. His feathers are a mess too, all different sizes and angles and his wings are far too slim to allow him to fly. Fushimi pretty much doesn’t give a shit though because of course his wings would be the kind that he couldn’t fly with and anyway he’s not like all those other idiots walking around trying to show their wings off or brag about their wingspan.
That’s when he meets Yata, who has these red and orange wings that look like a fire, but they’re really fluffy and the feathers are soft. Yata can’t quite fly with them but when he’s on his skateboard if he extends them behind him he feels like he’s flying anyway (oh oh imagine the scene from LSW with Fushimi, Yata and Aya on the bike, Yata’s got his wings out and they’re like stretching on either side of Fushimi so it feels like he’s in a tunnel of flames but he’s not scared at all, and behind Fushimi there’s Aya with her slim pink swan-like wings outstretched and then Fushimi unconsciously starts to stretch his too, the wings he always keeps hunched close and never spreads fully and for the first time in his life he really feels like he’s flying, there on the back on Yata’s bike). Yata’s the first person who thinks Fushimi’s wings are really cool, like look at how sleek they are and the black is so striking and the feathers feel super smooth, Yata loves running his fingers through Fushimi’s wings. Fushimi acts like he doesn’t care what Yata thinks of his wings but it always makes his breath catch a little, when Yata tells him how amazing his wings are. When the two of them move in together sometimes they lie side by side on Yata’s bunk discussing their plans for all the great things they’re going to do and Yata wraps his wings around Fushimi so that it feels like they’re living in this small cozy world, just the two of them, and sometimes Fushimi’s wings stretch just a bit to touch Yata’s, connecting just a little bit.
So then the surprise party incident happens and that’s when they meet Mikoto who has the biggest wings Yata and Fushimi have ever seen, these huge red ones with real fire blossoming along the edges and when Mikoto uses his Red King powers to the full extent his wings burst entirely into flame and it’s like a fireball. The rest of Homra have wings that are touched by fire in some way too – maybe people don’t just have feathered wings in this AU too, imagine Totsuka with wings that look like they belong to one of his flame butterflies (Anna’s ‘true’ wings are just coming in, downy white mixed with hints of red, and when she awakens as King all the white feathers fall to the ground like rain as she extends her red burning wings wide, a wingspan even greater than Mikoto’s, a phoenix rising). Fushimi’s actually afraid of Mikoto’s wings especially, like he can’t help but flinch every time Mikoto opens his wings fully. He’s also secretly jealous because Yata is so impressed that Mikoto-san can fly, and of course Fushimi knows that he’ll never be able to match that.
Then Fushimi meets Munakata and Munakata’s the only one he’s seen whose wings can rival Mikoto’s except Munakata’s are these sleek cobalt blue ones, growing brighter around the edges, just this amazing gradient of blue upon blue and Munakata loves to spread them wide whenever he’s making grand pronouncements. When he’s not trying to be impressive though Munakata keeps his wings neatly folded and sometimes they almost look like part of his uniform. Fushimi can’t help but feel drawn to those wings somehow and when Munakata tries to recruit him maybe instead of Fushimi’s leg moving unconsciously to Munakata’s side one wing opens on that side instead. Fushimi breaks things off like in canon, burning his tattoo and all, but maybe after he and Yata part he spots a fallen feather from Yata’s wings and ends up keeping it despite himself. Meanwhile Yata goes to pack up their old apartment and he finds one of Fushimi’s feathers. He wants to burn it into nothing but he can’t bring himself to do it, keeping it with him like tucked in his hat somehow and maybe it was one of those mottled feathers, black and red, and the whole time Fushimi thinks Yata’s been keeping one of Mikoto’s feathers when it’s actually his.
Then jungle, imagine Hisui’s wings aren’t real ones at all but these giant electricity ones that the Slate kinda made for him because when Hisui 'died’ his real wings hadn’t come in yet and being technically dead he couldn’t grow his real ones anymore. But the desire for them is there and the shape remains rooted in Hisui’s soul, how they should look, and the Slate answers that desire by giving him a mock version of what he should have. When the undercover mission happens Fushimi and Munakata fight and maybe Munakata makes a comment about Fushimi’s wings, the black color and how they’re so small and thin and useless, he’ll never fly with them and they’re really almost malformed in a way, just like Fushimi’s own twisted loyalties. Fushimi tries not to take that to heart but of course he does, even as he intends to carry out Munakata’s plan to the end.
Yata of course shows up to save Fushimi and when they escape Yata’s having trouble keeping ahead of Sukuna, like he’s on his skateboard with Fushimi on his back and Sukuna’s so close to catching up, and there are holes in the floor that Yata’s worried he won’t be able to skateboard over. Yata finally yells at Fushimi that they need to fly, Fushimi clicks his tongue because neither one of them can fly, idiot, and Yata’s just like shut up, I can’t fly on my own but if you’re with me we can definitely do it. They reach like this giant gap in the floor and Yata stretches his wings out, speeding up, determined to fly over it and save Fushimi. Fushimi stares at Yata in surprise and he finds his own wings stretching out too, all the way, the two of them flapping in unison as they just soar over the gap, completely airborne and in control and breathless for just a moment. Afterward Fushimi tries to act like it was nothing but Yata’s not giving up that easily, saying this is why he’s not letting Fushimi push him away again – sure they aren’t Kings and they can’t fly alone, but that’s why they’re supposed to be together because the only way Yata can soar is if Fushimi’s by his side.
