Do not kill the Stellaron.

Gray hair. Yellow eyes. A faint smile as they walk along the street, with two others by their side. The entity’s appearance greatly resembles that of a human, but. There is no mistaking that its true nature is something else entirely. There’s no hiding what lies at its core–

Do not kill the Stellaron.

–and the truth is plain to see: This entity is the living host to a Stellaron. And Stellarons, world-destroyers that they are, should be–

Do not kill the Stellaron.

“Don’t kill him,” Firefly’s voice is familiar. Familiarity should be soothing, but the words are wrong. Stellarons should be– “Shiki, don’t. Remember what Elio told you?”

Do not kill the Stellaron.

Stay your blade. Observe, and learn. Your time is yet to come.

Eyes drift closed in faint irritation, gray hair and yellow eyes disappearing from view. But there are a multitude of red lines that remain even despite the sudden loss of visual acuity, and the desire to cut is an immutable instinct engraved into the very being.

Control. Do not give in to base impulses.

Observe. Learn what lies at the core of a world constructed by dreams. Do not be distracted–

Do not kill the Stellaron.

Eyes open, surroundings drifting back into view. Clean streets, rich buildings. Splashes of pink and red covering the twilight sky.

… The Stellaron host is gone.

Sooo @astralpaint cooked up a zenith switcheroo and so here is part one of the angst train I was sucked into 😌

ZENITH ALOY - HUNTER OF HUNTERS

[robinpixels]

[fallen star au]

let's have a chat

[myrablurple]

Have another round of color palettes. 1st row: Lightyear Zurg :> 2nd row: Evil Empress Aurora AU of Aurora crying and Zurg, who in this AU ran away and became a farmer. 3rd row: Ty looking up at the green moon? IDK. I kinda took some DBZ influence to a possible transformation sequence. Then we got Buzz before ending it off with Tremendor

[snowe-zolynn-rogers]

So...Eclipse and Star now have a dad over on @ask-the-celestial-family. His name is Zenith, he was originally Eclipse’s kill code bits and he gained sentience because of ✨future trauma possibilities✨.

[the-starry-seas]

Okay been thinking about what's going on with Snack Squad in a sort of modern AU and I think I've got some things figured out. They live near (or in) a big NYC-style city where most of them work, although Zenith's work is the most distant from their house.

Winter: architecture professor

Bee: tech support

Indigo: art gallery secretary

Jewel: part-time rehab nurse

Nebula: accountant

Zenith: Forest Service pilot

Sunny: tattoo, digital, and traditional artist

Star: social media manager

Winter, Bee, Sunny, and Nebula share a six-bedroom house on the edge of the city that they got for cheap since it was in an absolutely ruined state. Winter had his heart set on it from the very moment he saw it. It took them almost a decade to finish fixing it up and plant a massive garden in the back with a few mature fruit trees. One of the spare bedrooms is kept for Zenith, and the other is used as a shared office since Bee and Nebula both partially work from home.

When Winter fosters the twins, Zenith's things are cleared out to move in two smaller beds for them. Zenith doesn't mind being moved out at all, especially when they end up replacing the backyard shed with a standalone studio that ey gets the key to. Ey jokes it's better that way because then ey doesn't have to listen to them being loud at each other. Over the next two years, they build a sunroom/office for Bee and Nebula, so the twins can later each have their own room.

Eventually Star moves in with them, when things get serious with him and Winter. He can work from home easily, and he loves the sense of community and belonging that the house has.

Jewel and Indigo share a loft in the downtown arts district, in walking distance of Indigo's workplace. They also share a bed platonically so the second bedroom is for Zenith. He prefers their place because it's much more conveniently located and also he worries about them being lonely since they live away from the others, even though they spend every other weekend at the family house.

Winter is highkey everyone's sugar daddy because he makes six digits and shares generously. You can't mention something you want around him without him finding a way to get it for you.

Bee is everyone's default "please help me figure out what happened to my wifi" guy and he allows it because Sunny always makes gingerbread snaps to thank him.

Indigo gets the entire squad into art museums for free. He's also connected to other artsy types and is always inviting the team along to indie film festivals, temporary museum exhibits, and other things they never knew existed until he brought them along.

Jewel uses the others' connections to help find hobbies and jobs for the veterans zhi works with, and brings home all sorts of gifts and freebies as a result. They've gotten quite an eclectic collection of gifts.

Nebula helps them with their taxes and gives Indigo's gallery a reduced rate on services as long as they showcase Sunny's work in the front room of their gallery.

Zenith hands out national park passes to everyone, whether they ask or not. Ey also flies Jewel and Indigo out on weekend trips when one of them gets an itch to visit somewhere, and helps arrange flights for all of their vacations.

Sunny makes dinners for everyone when they hit a busy patch. Xe's a great cook and baker, and it helps xer relax on the off chance that work is being stressful. Xe also makes vegan gluten-free chocolate chip cookies for Jewel to take to work.

[syensy-art]

Finally got around to adding a background to Celestial Zenith to match Wawel! From the same au, need to post Wawel here too though :] I had a lot of fun with these two designs!

[yuesya]

Uzui Tengen skids backwards, gritting his teeth. Raising the cleavers in his hands, he blocks another overarching strike by the cackling demon’s blood scythes, then counters by twisting and swinging–

Too slow. Tengen knows this, even before he has finished the strike. There are dark spots dancing in front of his eyes, and the pain that courses through his body from the demon’s poison is excruciating –but even so, Tengen does not allow himself to waver.

He can’t afford to. Not when they’re fighting Upper Moon Six, and when he’s the only Pillar present. Not when his wives and the young demon slayers he’d brought into the investigation are all at risk here.

“What’s wrong, Pillar? You’re starting to get slower!” the demon taunts, guttural voice laced with malicious glee and bloodthirst.

“Me, slower? In your dreams!” Tengen laughs confidently, even though he knows that the demon is right.

Shit. If only he hadn’t gotten himself poisoned at the very start of the fight–!

But there was no use thinking about what-if’s, not in the middle of heated combat like this. If things continue any further, then Tengen is going to die from poison before he’s able to cut off the demon’s head. He can’t let that happen, which means that he–

The demon’s expression suddenly changes, jerking and whirling around away from Tengen.

An opening!

Tengen lets out an irritated ‘tsk’ when he only manages to take off one of Upper Moon Six’s arms; the demon had dodged at the last moment. Dodged, and pulled away, disengaging from Tengen and flipping over to glower at whatever caught its attention–

“… It’s you.”

Amid the rubble littering the ground from their battle, there is a white-haired girl standing at the other end of the street.

… That’s the girl that Oyakata-sama specifically sought out and recruited, for the feat of–

“You’re the one who killed Upper Moon Three,” Upper Moon Six snarls. Its severed arm regrows in a flash, and it scratches at itself, sharp nails digging into disfigured flesh and trailing long ribbons of blood behind them. “I’m not like him, though. I don’t mind killing women.”

Tengen sucks in a sharp breath as the demon bursts into motion.

“His blood is poisonous!” he shouts, attempting to warn the girl. “Don’t let yourself be cut by his scythes!”

“Is that what happened to you?”

Oh, she’s good. In a single instant she’d avoided the rotating scythes that Upper Moon Six hurled towards her, simultaneously cutting off the demon’s legs at the knees as she did so, all in one fluid line of motion that almost made it seem as if she were dancing.

Strange blue eyes peer towards Tengen for a moment, which should be reassuring but instead only sends a sudden chill down his spine.

The girl reaches out and pats his shoulder. “I can’t use reverse cursed technique on others. But you won’t die from the poison like this.”

“Of course. I’m a shinobi, no poison can take me down so easily!” Tengen boasts, not quite understanding the strange words that she’s using.

Gojo Shiki had not been trained as a Demon Slayer, but there was no denying that she had been trained. No one unfamiliar with the art of combat would be able to take down Upper Moon Three, after all. It’s both humbling and slightly terrifying to know that this young girl in front of him had killed a higher-ranked Upper Moon while Tengen had been struggling against the weakest of the Upper Moons here, but–

More than any useless thoughts like that, Tengen is glad that powerful reinforcement is here.

We can do this. We can kill Upper Moon Six!

“My legs… my legs aren’t regenerating,” the green-haired demon murmurs, and then its face twists into a vicious snarl. “Is this wisteria poison again? My body will neutralize it in no time–”

“And you won’t have the time to do that!” Tengen thunders, racing forward with his blade raised–

–to block a sudden spire of solid ice that comes hurtling down out of nowhere.

The temperature in their surroundings immediately drops as the ice comes down, and Tengen frowns. There was no doubt that this was another Blood Demon Art, but it wasn’t the one that Upper Moon Six had displayed with his blood scythes. That meant…

There’s another demon here.

“Oh dear.” A new voice sounds in the nighttime air –one that sounds almost sympathetic. “Looks like you’re having a hard time here, Gyutaro.”

Upper Moon Six Gyutaro, who’d just been rescued onto one of the nearby rooftops by this strange new demon, glowers darkly. “I didn’t need your help.”

“Really?” The new demon tilts its head, and leans down to examine Upper Moon Six. “But you’re taking so long to regenerate, Gyutaro. I was worried!”

“You were not.”

The new demon laughs, and lifts its gaze towards them. Tengen’s blood runs cold when he finally sees the characters etched into its opalescent eyes, illuminated by the firelight.

Upper Moon Two. “Ah, I’m so glad I decided to drop by!” The demon smiles invitingly, evidently delighted as it surveys them and claps its hands together. “I just had to come, y’know. After all, I heard that the demon slayer who killed Akaza was a lovely young lady with the most beautiful eyes. How could I possibly resist staying away after hearing that?”

𑑛 “SWELTERING SUMMER” ﾉ DR. RATIO. HONKAI STAR RAIL. ANTIQUITY AU

fem reader ﾉ words 2.5k ᯽ spending a hot day inside the house. established relationship but also lowkey unspecified what kind of relationship lol. flirting while eating fruits. lots of kissing and making out. bit of dry humping on the floor. lowkey soft veritas. nipple teasing. cumming inside ﾉ just slightly proofread, forgive me for any mistakes ᯽ ADULT CONTENT ﾉ MINORS DO NOT INTERACT ᯽

little dictionary ᯽ atrium — a courtyard with an open roof in the middle of the villa ﾉ impluvium — a shallow pool below the open roof (compluvium) that collects and filters rainwater, cooling the room during hot weather.

A hot day it was, scorching sun high up in the skies casting a pale alabaster heat on stone villas and plants spreading their leaves wide to absorb every beam. The good thing that the roof kept the atrium mostly in shadows until late afternoon where the star gaze upon the courtyard at the perfect angle — but now all it does is turn the shallow pool into a vase full of diamonds, small waves sparkling and shimmering in white glitter each time you kick your feet gently against the liquid surface.

“Mmm… This way it’s bearable. The day, I mean,” you hum, lost in thoughts of how awful it would be now to stand in the middle of the agora. Instead, you’re lazing around his villa, snacking on his fruits and enjoying his company.

“Only an idiot would go out when the sun is in its zenith. Actually, there are not many sane people out there. Regardless, do you plan to squander the rest of the day on meaningless rumination?” Veritas asks, quirking a brow and piercing you with an intense look from the other side of the atrium, open space merging with this study. He doesn’t sit next to you, but his gaze feels closer than the distance between you two suggests.

You are almost naked — barely a piece of cloth draped over your intimate parts — on the warm stone bench, skin gleaming from the cream, on display like an offering for his eyes. You don’t touch each other and yet, you do.

Your shoulders sag slightly when you hear him call you out on your foolishness; the corners of your mouth pull upwards as you look at him, staring through half-lidded eyes at his beauty like he is another sun and you may go blind.

“Don’t be mean! Not everyone has the energy to make a scientific discovery when breathing alone takes away any motivation!” you whine at him with mouth full of cold grapes, which results in him rolling his eyes at you.

Alas, he’s also standing up and stepping closer.

You watch him take a piece of the peeled orange, only to eat it in front of you. And that would have been enough for your eyes to follow his lips, as well as for your heart to speed up, but Veritas takes it a step further and slowly wipes away the juice dripping down his chin with his thumb, before bringing it to his mouth and licking it off. Your brain immediately screams at you for being so obvious, stupidly fascinated by the man as you stare at his wet thumb, then at his tongue and lastly at his beautiful lips.

At this point, you have already forgotten what you were saying before he interrupted you.

“You might not possess any desire to concoct hypotheses, nor do you long for scientific development, but seem to be perfectly capable of thinking lustful of me.”

This makes you drop the bunch of grapes you had been about to eat and splutter in denial, scrambling to collect them off the floor. They’re dusty now, so you try to clean the residue in water. It doesn’t work as well as you wish it did, but once again, you fail to realise Veritas staring at you.

He waits patiently for you to finish cleaning up after yourself, sitting next to you. Clearly amused at your display of nervousness, his palm travelling along your spine and pulling the cloth just an inch to the side to let it slide on its own from your body. You look at him wide-eyed, at the small smirk on his lips and the intensity of his eyes; it takes you a moment to comprehend what is happening.

He pats his thigh and you sit there on the mosaics, biting your lower lip and pretending not to want to wrap your legs around his waist and nibble on his neck. But he can see through you.

He always does.

“I can spare you some time. Don’t waste it, indulge yourself. Come here,” he orders and you do so immediately, nearly dropping the grapes again in your haste to obey.

The cloth uncovers your entire chest by the time you straddle his lap and he sighs contentedly at your nakedness, stroking your sides from ribcage to your breasts, weighing your tits before he leans forward, taking it into his mouth and biting down slightly, making you yelp.

You circle your arms around his shoulders, pull him closer to you and press your lips against his neck, murmuring his name, all while he moves his hands to your ass, grabbing on the soft flesh and pulling your pelvis closer to his own.

It makes you want to bite down on the ivory skin on his shoulder, but instead, you mutter out, “this won’t help us cool down…”

And he replies, “as if I’m going to believe you won’t pout at me if we stop now. Would you really like to part with me?” as he says it, his thumbs swipe like feathers up your buds, eating a shudder consuming your entire silhouette.

He looks down to see your nipples harden, before you embrace him tighter and place a sloppy peck on his cheek, arms hugging him from behind, fingertips pressing into his back to have an excuse to make him not stare. You can feel his smirk against your neck.

This time he lets you lead, fingers threading through his hair as you make out with him in the empty atrium. He sits perfectly still beneath you, athletic legs spreading your own apart even more until there is no room for doubts that he likes what you do to him — your folds sliding along the hot length of his cock. His tongue runs over yours when you slip it inside his mouth, exploring him like you did not already do that once, and twice, and countless times.

You remember when he showed you how to kiss properly and gave you instructions on how to make him pleased. You were innocent then, shy as he made you take off your tunic and examine his naked form. Now, you yearn for his body as he does for yours, trembling in anticipation when he uncovers his perfect skin.

He used to teach you all sorts of things, but they all led to this very moment when he lets you ride him in his own house, feeding you his fruits and welcoming you anytime you wish to busy his precious time.

Your arms lock behind his neck, pulling him even closer, fingers entangled in his long hair as you continue making out. He takes a hold of your hips and stills you, rubbing his thumbs into the soft flesh before letting go, sliding down your ass to rest on your thighs.

He likes this, the feeling of your hands in his hair, your fingers playing with his long tresses, taking the strands between your digits and making them dance and wave like silk. He enjoys it more than you do.

And when you hear his exhale, it sends shivers up your spine — a moan right into your mouth as you both enjoy the other. You notice the tip of his tongue peeking out of his lips and you capture it with your own, closing your mouth around it and sucking gently. His nails dig into your flesh when you do this, sharp and unannounced, but definitely not unwanted.

“Already?” he whispers with a tint of mockery in his voice, feeling your shaky fist sneaking between your bodies to find his cock. Your finger brushes against the wet slit at the head, stroking him teasingly, just like he showed you before. But it’s obvious by now that you’re one mewl away from pouncing at him, trying to fit his entire girth inside.

However, Veritas has a little more self-control than you do and when he senses your impatience, he places his hand on top of yours and stops your ministrations. Then he leans in and pecks your lips before guiding your palm away from his hard length, placing it back on his chest.

You sigh against his lips, clearly disappointed.

“I know well that you want it just as much as I do…”

“Perhaps.”

“Then…? Please?”

He tilts his head to the side and takes in the sight of your naked form, bare for his eyes to drink you in and make you feel exposed, vulnerable. Then he glances down, lets his gaze trail from your face to your chest, takes in the view of your nipples — peaked and glistening from his saliva — before lowering it even more and shamelessly staring at your cunt.

You gasp quietly at his intense stare, feeling yourself drip when he parts your lower lips with two fingers and, with a subtle roll of his hips, let the glossy cockhead greet the revealed clit. It is merely a moment, yet you could see how good it would feel if he were to slide in.

But he doesn’t do that.

He leaves you there on the edge, all bothered and horny, covered in your own slick.

His tongue slides along his lower lip as he reaches down to squeeze himself in hand, smearing your wetness all over the shaft, coating it in your nectar.

The sigh he lets out is enough to make your legs weak and for you to press yourself against him, bare skin sticking together with sweat — the sweetest kind.

“Use your words.”

You huff in frustration at that, shamelessly rutting against him, desperate to have him inside. Your own juices flow freely down your thighs as you pant into his ear, incoherent pleads leaving your mouth before you finally manage to form a sentence.

“Inside… Please, let’s just continue. I want you in me…” you whisper against his lips and he sighs, lifting you up like you weigh nothing and slipping inside. Your body gives in easily, swallowing him to the hilt with a sweet moan that he kisses out of you.

“Happy now?” he asks and you nod. It is quite indescribable.

“Happy. Happy with you.”

His smile is genuine and your eyes flutter closed when he moves your hips up and down, thrusting into you slowly at the same time. It sends a wave of pleasure through your entire body and your soft pussy pulses, drooling arousal around his shaft until it’s too easy to glide deep enough to meet your womb.

The afternoon heat makes the entire scene feel like a dream.

It is too hot to move, but the water soaks into your skin, cooling you down. His fingers squeeze your asscheeks, spreading them apart, leaving them covered in goosebumps. You moan his name loudly when he leans in to smooch your nipple and then suck on it gently, all while moving you against his pelvis, putting more force into every thrust as he rolls his hips, burying himself inside you.

Veritas shudders with every small noise that leaves your lips, his eyelids heavy as he watches you — face twisted in pleasure, head thrown back and hands grasping at his shoulders for support. He places his palm over your stomach, pressing down to force you to tighten, feeling your muscles throb with life inside you.

When he bucks up into you, a lewd wet sound fills the air, making your cunt contract around his cock.

The soft click of his tongue between teeth is enough to let you know he likes it. You try to look at him through hazy eyes, but you don’t last long before your lids close once again and you surrender yourself to his ministrations.

Then he smiles against your lips, teasing you by pulling away just when you lean in for a kiss.

You squeeze your thighs together as much as possible to hold him inside, but he only needs to pry your legs apart to continue the pleasurable dance. There is a faint sound of water dripping from the aqueduct outside his atrium and it echoes against the walls.

You try to grind your hips down to meet his thrusts, but he only moves slower, murmuring into your ear that you will not like it if you overdo it. It feels almost overwhelming at this point. You let out a groan when he cups your tit, presses it up, rubs his thumb against the stiff nipple and leans down to nip on it again, tracing around the areola before gently nibbling on the bud, feeling your pussy contract every time he bites.

His other hand slides up your spine, between your shoulder blades and then up your neck, tangling in your hair. You can barely stay up at this point, with his girth inside you, keeping you full and his teeth biting into your skin — if it weren’t for him holding you close to his body, you would collapse onto the floor, spent.

There is no time for teasing as he thrusts into you again, harder than before, almost lifting you up. When he starts moving your hips for you, you can only moan, clinging to him, fingers clutching at his hair.

He fucks you like this for a moment, feeling your cunt pulse around him, slick dripping from you with every push of his length inside you. It makes a mess on his thighs, leaking down onto the floor, and you beg him to come soon before you give in to the pleasure rush yourself.

It does not take long for him to lean back, support himself with one arm against the mosaic floor and hold your hips still as he buries himself deep into you. His breathing is shaky and laboured, making you worry he might lie down or lose balance, but then he sits up, embraces you tightly and buries his face in the crook of your neck, trying to calm down.

Warmth coming from within, his cum filling you up, a scorching heat of desire that could only rival the temperature outside. You feel him throb with every drop that spills out, in tandem grinding your clit closer to his skin and prolonging your own orgasm. The entire experience makes you whimper his name softly and press closer to him, your breasts squished to his chest. He feels you hug him, hear you sniffling quietly as you shudder with every wave of pleasure passing through your body, rubbing your cheek against his shoulder and crying out when it gets too much.

Veritas doesn’t want to part from you just yet.

So he stays inside you, chest rising and falling with heavy breathing, lips leaving soft kisses on your shoulder. He picks up a grape, feeds it to you, listens to you chewing on it and chuckle as you frown, clearly confused at the gift to bite on but happy with the ripe taste. You look up at him and ask if he is finally satisfied.

And he responds, “with you? Yes.”

Sooo @astralpaint cooked up a zenith switcheroo and so here is part two of the angst train I was sucked into 😌
