This AU don't have sense. This exist cuz I like the aestethic of Kabukimono and Abyss Prince together, lol. This is something I wrote last year. Here the two "chapters" and two silly chibis









Hi this doesn't necessarily have to be a request but what do you think about the concept of dating abyss prince!aether? I think it's a very interesting concept especially since we as fans only know so much.
i was going to write this as a request, but i feel like i wouldn't be able to accurately express how strongly i feel about this in such a structured manner LMAO
so here we go Messy Format, i am so sorry y'all, i've been lacking lately... i promise i'll do better,,
anyways, abyss prince!aether x gn!reader below the cut <3

how would you even meet?
a fantastic question!
so, for Dramatic Plot Reasons, you are actually lumine's second travel partner, right? and you help keep her on track while she searches for answers for aether's whereabouts
like after the dvalin incident when lumine is asking venti questions and receiving vague answers, you are beside her, glaring daggers at the former archon in an effort to get him to talk.
"we didn't save your people just for you to be tight-lipped." you snarl. "this one-sided transaction shit won't fly."
lumine tugs on your arm as a warning and waves apologetically at venti. all of you just encountered la signora and watched as he was forcibly stripped of his gnosis -- of his divine status. venti is already a shadow of his usual self as it is, and your harsh words weren't helping.
"i-i'm sorry venti, ignore them." she apologizes on your behalf. lumine gives you a look of disbelief when you yank yourself out of her grip, but says nothing. "thank you for your information. it really helped."
"like hell it did." you mutter under your breath.
venti gives you a patient smile; the one he gives everyone when he's not in his usual playful mood. "their anger isn't misplaced, traveler," he hums, "i really am sorry that i only gave you more questions than answers, but i promise you: morax is the oldest of us all. he'll have the answers you need."
i think i'll cut that there, because i just want you to understand that at the beginning, you are lumine's backbone
you say what she's too kind to say
her desire to find aether consumes her every waking moment, but she just can't ignore people in need! so she can put her mission on the back burner for just a little longer, right?
wrong. you completely disagree.
you'll let her do what she needs to do when it's unrelated to your quest, but as soon as you're with someone who may possibly have answers, you put your foot down.
sometimes, lumine would joke that you want to find aether more than she does
you don't even know what he looks like. you just want lumine to be happy. she's your best friend
so where does aether come into all of this?
this is where we diverge from the plot.
you first encounter him on a late night walk through the forest.
you and lumine were camping out for the night after a very long day of running around with klee, jean, and albedo
you were feeling restless all day, but you couldn't figure out why
for some reason, for the past couple of days, you've been feeling... watched. you feel like there's someone watching you at every corner.
you're with lumine at almost every hour of the day, but even when you two are apart, you feel those eyes still on you
so you're strolling through the forest, trying to keep yourself sane when you stumble across a small hilichurl camp
it's nothing serious, just a few shooters and one big one with a shield
you easily handle the shieldwall mitachurl and the pyro and cryo shooters
but during your fight, you didn't hear the warning horn calling for backup.
you're dusting off your clothes to head back to camp when you hear something heavy slicing through the air behind you
it's an axe mitachurl
you react far too late to stop it, so you close your eyes and say a silent goodbye to lumine as you prepare for what you assume is the most painful death known to man..
but it never comes.
you crack open one eye to see what has so graciously allowed you to live another day only to find that it's not a what, but rather a who. the mitachurl from before is disintegrating on the ground behind the person's feet, so you open your eyes to get a better look at your savior.
it's a man with long, blonde hair, golden eyes, and peculiar clothing. something starts to click in the back of your head, like rocks sparking to make a fire. do you... know him?
rather than look at the faded body of the monster he just defeated, his eyes are fixed on you, his expression unreadable.
"um," you mumble, "thank you...?"
your savior raises an eyebrow. "are you trying to get me to tell you my name?" when you nod, he huffs a humorless laugh. "you'll figure it out soon enough. but, i will admit, i was under the impression that you were a lot stronger than this."
you blink a few times out of shock. was he insulting you? "pardon me? i just didn't hear the warning horn. it wouldn't have been the first time."
the blonde man turns around and walks away from you, and it's only then that you see the white and gold sword disappearing from his hand. "it would have been your last, had i not stepped in." he turns to face you again. "otherwise, i think lumine would have had to find your body herself."
lumine? he knows lumine? the sparks in your head ignite so quickly that you become dizzy.
"aether?" you say in a hushed whisper. you're far away from your campsite, but you say his name as though it were the most scandalous secret you've ever been told. "is that... are you aether?"
somewhere deep down, you hoped to celestia that you were wrong. you really did. but when aether's lips split into a solemn smile, you feel guilt and panic begin to twist your insides into knots. "y-you're here," you stammer. "i have to go tell lumine--!"
you start to run back but aether is swift, catching your wrist in an almost bruising grip. you whirl around to look at him thinking he would be furious with you, but instead, there's a forlorn look swimming in his eyes. your heart tugs; he looks just like lumine. there was really no doubting that they were twins.
"don't," he shakes his head and lets go of your wrist, "don't tell her that you've seen me."
"why? she's running herself ragged looking for you!" you feel sick to your stomach. he expects you to keep this a secret? this was why you were with lumine -- why you stuck by her side even in the worst of times. it was all for the sake of finding him. "you two could go home and be together again, but you're just... you're going to abandon her?"
aether's face darkens for a moment, but he seems to realize something before it levels out. "i'm... not abandoning her. it's just that there are some things she needs to do -- that i need to do -- before we can leave." he glances in the direction of your campsite; it's like he can sense lumine's presence. the white accents of his clothing and jewelry shine a little brighter as he speaks. "she needs to find her truth. i've already found mine."
you feel suffocated. there's so much going through your head -- so much wrong with this situation. you don't want to do as aether says, but you would be lying if you said you didn't feel power radiating off of him. it's the same kind that you felt from lumine, but aether's was so densely saturated -- so much stronger than his sister's. did he manage to get his old powers back, then? if you were to disobey him... what would he do to you?
aether's eyes flick back to you. "you're thinking that i'm going to hurt you." it's not a question. he knows.
you shake your head but it's useless. he's already picked up on it.
"i guess i'm not as... approachable as my sister." he chuckles to himself. he steps closer to you. "but i'm not going to hurt you. if i was, i would have let that mitachurl do you in."
"th-then what do you want from me?"
"your silence." aether hums. "and," he walks to a tree behind you, picks a windwheel aster from the ground and comes back to give it to you. "your attention."
he wants your attention? "if it's my attention you want," you reply, taking the flower from aether with shaky fingers, "then you already have it."
aether laughs again. he's been doing that a lot, you notice. is there something amusing about this? "i don't mean your attention in that way. in due time, however, i trust that you will understand what i mean."
"what?"
in the distance, you hear the howling of a wolf. the moon must be at its highest now. aether's eyes follow the noise before centering on you again. his gaze softens when he sees you tense under his stare. "it's very late. you should go back to bed." he says softly.
something about his tone makes your breathing become uneven. "what if i tell lumine?" you say. "i-i could tell her everything. i don't have to listen to you."
aether nods. "you're right, you're right. but," he steps away and makes his way deeper into the forest, "i trust you."
and just like that, he's gone, leaving you with the spinning petals of a windwheel aster in your fingertips and the smell of stardust in your lungs.
what then?
you don't tell lumine.
when you got back to camp that night, your best friend was awake and frantic, because she had no idea where you'd gone and because you didn't use your vision, she couldn't trace you with elemental sight
she was so afraid that you'd abandoned her too
you were in such a daze that you didn't know what to say, so lumine assumed that you ran into some terrible danger
it wasn't inaccurate, so you let her believe it
but you didn't tell her the truth.
after that, you begin to see aether more and more often.
mostly in passing, but you notice that he's actually trailing you two
but whenever he catches your eye, you notice that his eyes are locked on you and not his sister
you only talk to him at night, when the world has gone to sleep
aether reveals himself to you when you're alone and jerks you around with his cryptic speech and charming smile
every time, he tells you how much he trusts you, because you haven't told lumine of your nightly rendezvous with him
and every time, the guilt grows stronger.
partially because you're hiding such a big secret from your closest friend
but also because you know when you're falling in love.
what is loving the abyss prince like?
it's suffocating at first.
you shoulder the weight of the world by loving him as much as you do.
at first, you tried to convince yourself that it was hatred.
hatred for the man who forced you to be a liar
hatred for the man who gifted you flowers and exotic trinkets from the nations you hadn't visited yet
hatred for the man who embraced you like you were the most delicate being on the planet
because you came to yearn for his presence
nights when he didn't visit were the worst nights of your life
you almost had withdrawals whenever you couldn't see him
you tried your best to restrain yourself when you two would reunite after a while, but aether could always pick up on your neediness
you hated him, you tried to tell yourself
you hate him you hate him you hate him.
you don't know when that changed.
but you knew and he knew that neither of you were going to make it out of this strange relationship without heartbreak.
aether confesses to you on the peak of starsnatch cliff.
"to the people of mondstadt," he speaks to you over his shoulder as he plucks cecilias out of the ground, "people who confess their love here are fated to be together for eternity."
the very second those words leave his lips, your heart stops. it's a common thing whenever you're with aether. he makes your body do the weirdest things with the littlest behaviors. his words could stop your heart and his smile could make your mind melt. it was wrong -- it was so, so, so wrong -- but you couldn't stop it.
you try in vain to keep yourself calm. "why do you know that?" you ask. you're often blunt with the prince of the abyss. he's told you on multiple occasions that he finds it endearing, since most of his subjects wouldn't even dare look him in the eyes. you hear his tinkling laugh from behind you.
"just a bit of trivia for you." he says. he stands and heads over to you, sitting beside you on the grass with the little bouquet of cecelias in hand. their light fragrance carries on the breeze.
"i've always found mondstadt to be one of my favorite places in this world." aether muses. his eyes close and your fingers itch with the urge to touch his face. his eyelashes are as golden as his hair, long and beautiful. "nowhere else is as tranquil as this place. i've sent barbatos my kind regards more than once."
you gape. "you're on good terms with the anemo archon? but i thought you.." you trail off. aether's told you his story already -- his mission. he's so transparent with you that it makes you want to bury your head in a hole.
aether removes the gloves from his hands and gently strokes the flower petals. "i may be working against the archons, but i'm not that immature. i know guilt when i see it." he looks at you then. you freeze. "i know you feel guilty about this. about us."
"there is no us." you say. the words feel so bitter and disgusting on your tongue. "there's not supposed to be an 'us'."
"and yet here you are." the prince reaches out and cradles your face with a hand. "letting me touch you like we're lovers." he smiles when you don't pull away. you may not notice, but you relax at his touch. his hands are warm and calloused, his fingers and forearms scarred from centuries of battles fought and won. they're comforting to you, no matter how much you want to deny it.
you bite your lip. you can't lie to yourself anymore. you've lied to enough people as it is. you rest your hand on the back of aether's own. "why are you doing this to me?" you ask softly. your voice cracks.
rather than answer you with words, aether leans in and kisses your forehead. your skin sings at the contact. "because you're intriguing." he murmurs against your skin.
you laugh wetly. "you always say that. i need a real reason."
he kisses your cheek. "because you're capable," he continues. "you're mystifying," he kisses your other cheek, "you're trustworthy," he kisses your nose, "and because i..." aether stops and presses his forehead against yours.
you don't think you're breathing anymore. elation has built so much in your chest that you think you're going to burst. "because what?" you whisper. "why do you stick around me so much, aether?"
"say it again." he says. he closes his eyes with a sigh. "my name. say it again."
you obey. "aether."
"again."
"a-aether," you stutter, "what is this about?"
aether silences any other questions you may have with a kiss. it's the ghost of a kiss, really; a barely-there brush of lips that sets off fireworks in your head. "you asked me why i'm doing this." he speaks against your mouth. "it's because i'm in love with you."
you don't mean to say his name again, but it's the only word you can think to say in response. he kisses you properly this time. "aether, i can't," you feel like your very soul is shaking. you're conflicted, but if this goes on any longer, you're going to make your decision. "this is--"
aether kisses you again, drinking in your half-hearted protests. "you feel the same, don't you?" he asks when he pulls away. "i know you do. you wouldn't let me kiss you if you didn't."
"what did you do to me?" you feel a lump in your throat. you've never felt love so genuine -- so pure. but to feel that from the prince of the abyss order? it was tearing you apart. "why do i love you so much, aether? why?"
the prince kisses you. "tell me you love me again. please."
"i love you." the words come straight from your chest; from the deepest, most sensitive place in your body. you mean every word, every syllable. "i love y--"
another kiss. "one more time, star. just one more."
you sniff. you don't know when you started crying, but you are. aether's other hand cups your face, brushing your tears with his thumb. "i love you." you whisper. "so, so much, aether."
aether sighs, finally content. "and i love you. more than there are stars in the sky."
beneath those stars, your abyss prince kisses you tenderly, murmuring words of adoration all the while.
where does your relationship go from here?
from here, nothing changes.
you're so used to lying to lumine that you don't change how behave during the day
your nightly meetings with the abyss prince become more intimate, with you two always touching in some way
he tells you stories of himself and lumine in the past
or maybe he'll tell you of the happenings of the abyss
he does so in order to keep you and lumine out of trouble
aether doesn't hide a thing from you because you've already proven yourself to him
he was drawn to you because of your ability to keep his other half safe
you were helping her reach the answers he wanted her to reach, even after you two became official
at night, aether will sometimes fantasize about taking you along with him and lumine when they leave this world
there's so much he wants you to see, so many things he wants to show you -- to experience with you
but until then, he must complete his work here
there will be nights when aether is too furious to touch or speak to you
he trusts you, but not himself
because he's been the ruler of the underbelly of this world for so long, he feels as though he shouldn't be around you in fear that he will ruin you
that you will become a monster much like him
but really, all you need to do is remind him that you trust him.
kiss him all over, hold his hands, braid his hair, stay close by
because that's more than enough for him to understand that he's not some weapon of mass destruction -- that he's capable of good and deserving of love just like everyone else
he is still just a man lost without his family
he's so torn up about not being able to be around lumine, but the day when he can be around her -- when he can tell her the truth -- is quickly approaching
and it's all thanks to you
because of you, the twins can see each other much sooner than aether planned
you and aether plan to slowly ease lumine into the truth of your relationship when it comes time to tell her
but there will be no more lies. not anymore.
lastly, what is he like as a lover?
lumine told you once that her brother was a very tactile person
he's always been the more compassionate out of the two of them, so he's a hands-on kind of person
something you learn through experience
he's always touching you in some way, be it your hands, shoulders, etc.
he also always takes his gloves off if he's going to touch your skin
very big on cuddling... abyss prince or not, aether just... really likes the warmth of someone else.
aether has a very stern side to him that you see on occasion
mostly when he talks about what he does during the day
his eyes grow dull and his tone will freeze over. his face will lose all of its usual warmth and he'll probably squeeze whatever it is that's in his hands
that's really just a fraction of what he's really like when he's carrying out his duties as prince of the abyss.
also very big on gift giving!! he'll give you little things here and there, but there has never been a time when he hasn't given you something.
i think that aether is a very passionate lover, abyss status or not
but because of his duties, you need to be patient with him. he's prone to moments of panic or lashing out of anger
never directed at you, but things pile up during the day and he has to keep it in to maintain his reputation

✧ i feel like this was not exactly what anon asked for but i'm so?? in love with this idea?? yes yeah.
