DAY 25 OF #NOVEMBER, WHERE I POST IN NOVEMBER
Wasn't too sure what to do today. So, because I haven't really done this before, I decided to do little character profiles! The three protagonists and main antagonist of the thing I'm very slowly but surely writing. #Koikatsu #コイカツ #OC
HEIKE MEINHOF RACE: HUMAN (HUNTER CASTE) AGE: EARLY-MID TWENTIES NATIONALITY: SOUTH NOVOSEL OCCUPATION: FREELANCE HUNTER An eonist, Heike was born in a tavern in the town of Werfen to an Albian drunkard who had had a fling with the disgraced Novosel Hunter, Ansel Meinhof. In Nineteen-ten, when Heike was a child, Ansel was executed as one of the ringmasters of the failed Gesellschaft Coup. With a tainted family legacy and a lot to prove, Heike sought to move out from under her father's shadow and become the best Hunter of her generation. She succeeded. Eventually, Heike began to believe that she was the pinnacle of human development, the strongest, most beautiful woman in the world, wielding womanhood of her own making. Now, she finds herself facing something altogether inhuman that threatens her spot at the top of the food chain. AYESHA AN-NASIRI RACE: HUMAN, FOR THE MOST PART AGE: MID-THIRTIES, POSSIBLY NATIONALITY: UNKNOWN, FEELS SOME CONNECTION TO OLD ARAM OCCUPATION: UNEMPLOYED DRIFTER In truth, Ayesha remembers nothing. No parents, no childhood, nothing. There are flashes of memory, but they couldn't possibly be hers. Memories of Aram as it was thousands of years ago, of healing the sick, travelling to the ancient rice-Kingdoms of Wa, and performing a grand sacrifice for humanity. All of it is jumbled. None of it makes sense, and the only clue she has to go on is the set of scars on her hands and feet. Now, having woken up in the war-torn ruins of Versailles, Ayesha must use any ally she can find to figure out her identity, find her purpose, and evade the mysterious angels who would do her harm. MIRCALLA KARNSTEIN RACE: VAMPYRE (PASSION-EATER) AGE: TWO-HUNDRED AND FORTY NATIONALITY: STYRIAN (DUCHY OF STYRIA, NO LONGER EXTANT) OCCUPATION: UNEMPLOYED, LIVES IN THE RUINS OF HER OLD MANOR In Sixteen-Ninety-Eight, the House of Karnstein went bankrupt. During Hulda Karnstein's last ball, the daughter of the house, Mircalla, was transformed by Lady Hulda's vampyre boyfriend. However, her unique circumstances resulted in her becoming a different type of Vampyre, the Passion-Eater. The second spree in Eighteen-Sixy-Four was Mircalla's last, for she fell in love with her prey, one Laura Wachter. To this day, Mircalla uses the alias she used with Laura, 'Carmilla'. Having awoken once more, Carmilla finds herself thrust into a war she doesn't understand, though she wishes to use the opportunity to find some trace of Laura. SAMAEL RACE: ANGEL (USING A HUMAN HOST BODY) AGE: AGELESS (HOST BODY DIED AT THIRTY-SEVEN) NATIONALITY: NONE (HOST BODY WAS FROM HOLY ROMAGNA) OCCUPATION: DIVINE CONQUEROR (HOST BODY WAS A ROMAN PALADIN) In the year nine-hundred, an Angel opened the rift between our reality and the Plane of Irkalla, which unleased millions of Demons and caused a war that destroyed Heaven and nearly destroyed Earth. Humanity was led to believe that Lucifer was the fallen angel responsible. In reality, Samael was the one who wished to destroy the World of Man. Now, to atone for his destruction of the Divine Realm, he wishes to sit upon YHWH's throne and rebuild with the most divine material of all: YHWH's final creation, Man itself. To empower the host body, a knight once called Don Benito, Samael intends to gather the last divine traces of the Nazerene, including the Reincarnation, Ayesha An-Nasiri.

In 'Way of the Samurai 4', there's a character who's technically named "Melinda de Cameron" in the original Japanese, but because of the pun involved ("deka meron"), it got localised as Melinda Megamelons.

DAY 24 OF #NOVEMBER, WHERE I POST IN NOVEMBER
While it's been slow getting my group into the actual game, I'm halfway convinced @shimbolus.bsky.social's character Ingfried can and will solo Curse of Strahd. Here is one likely method. #Koikatsu #コイカツ
Strahd Von Zarovich, an insufferable vampire with long black hair and angular features, kneels appraisingly over Ingfried Kriegmonte, the blonde-haired adventurer he's just defeated. Ireena Kolyana, a dark-skinned, red-haired woman, also kneels defeated in the background. The scene takes place in a forest, with a dark red sky. The scene has switched to an ornate room, probably Strahd's castle. Ingfried stands over Strahd, grabbing his bare legs, with a wicked grin on her face. The tables have seemingly turned. Ingfried is sitting on Strahd's table, with one leg wrapped over Strahd's back, and her enormous cock uncomfortably close to his face. Ireena is behind Strahd, grinning madly at him with her own huge cock out.

DAY 23 OF #NOVEMBER, WHERE I POST IN NOVEMBER
Excited to revisit my Metal Gear yuri. This isn't canon to the little thing I plan on doing, but it kinda just came naturally, so y'know. #MetalGear #Koikatsu #コイカツ
Ashen Swan, an MSF operative, in the woods watching a Soviet convoy. Four other soldiers are in view, including a female VDV paratrooper, Alina. Alina, the VDV paratrooper from the last image, choking Swan near the vantage point. Two of the other Soviet soldiers are unconscious nearby, suggesting that Swan made a move before getting discovered. There is a light purple glow/blush through Swan's mask, which you can interpret as either lack of air, or enjoyment.

DAY 22 OF #NOVEMBER, WHERE I POST IN NOVEMBER
As national heroes, Novoselic's 'Holy Hunters' are often egotistical and rude. Heike Meinhof, known as the 'finest of her generation', takes this smug attitude to another level, to a point where she believes she's the perfect human being. #Koikatsu #コイカツ
Heike, a trans woman in leather armour, jumping up at an angle with an anti-tank rifle and a sabre, DMC-style. She's pointing her ridiculously big gun into the mouth of a giant Beast, with a glow from the inside implying firing. A city of gothic spires is in the background, partially covered by the evening clouds. Heike, from before, in the middle of a rather ornate brick city, with wooden market stalls in the background. She's staring down at the viewpoint/camera, leaning and smiling smugly. Ditto, underwear variant. Ditto, flashing variant. Heike is looking up a little more, showing her eyes where the helmet previously hid them. Also her cock is out.

Still a big fan of @shimbolus.bsky.social's new outfits for Seohyun. Wasn't sure what to do for most of today so this was kind of a quick one #Koikatsu #コイカツ
Seohyun, in a classroom, looking sideways at the camera with a smug expression. Polly is in the back with her flip phone. Seohyun squatting, with Gracie in front of her. Polly is in the background with her flip phone.

DAY 20 OF #NOVEMBER, WHERE I POST IN NOVEMBER
So, for all the talk of @shimbolus.bsky.social's setting, The Spiral, we never really bring up the big antagonist group, ARES. These might give you a good first impression of both the faction and the leader (both named ARES). #Koikatsu #コイカツ
A propaganda poster, depicting ARES (the CEO), an extremely tall woman with a metal face, aiming/conducting a giant cannon while identitcal soldiers kneel behind her in rows. The text reads as follows: "ATTAIN VICTORY, ENLIST WITH ARES. NEAREST ENLISTMENT CENTRES: ANURAK SAETANG ELEMENTARY SCHOOL, SNUSHI DEVELOPMENTS PLAZA, FRONT DESK, THE ARES BUILDING. END THE ANARCHIC LEGACY OF HELLION'S WAR." ARES clashing with Viktoriya Borisova, the CEO of rival Hellion PMC. The sheer force of their fight seems to have made a mess of the environment behind them. Ditto, explosion/shockwave alt. ARES standing in a barren desert atop a hill. Her shirt falls away behind her, on fire, while she bares all. Both her arm and the leg of her pants also have caught fire. In the background, destroyed buildings and pieces of rusted mechs litter the desert landscape, and embers float through the air. In the foreground, Vik from earlier is in a fighting stance, her own clothes having been burned away in much the same manner, leaving her only in her gloves and partially her pants.

Not sure if I ever posted this guy before, but I'm not quite in the state to do stuff in koi right now and these old images are a good substitute
Here's Lonnie, a comms officer and handler for Hellion PMC, and also a total slut. #Koikatsu #コイカツ
Lonnie, a transmasc bunny boy with blonde hair with a white streak in it. He's sitting at an office meeting table, with various items around him, including a couple of old radios, a handheld console, a coffee cup and a book. Ditto, lewd alt. Lonnie sitting by a wall, wearing boxers only, holding a beer bottle.

This was a very fun one to do! Technically three variants of one image, but enough variety in there to be super fun! Samir and Galatea on a true world tour! For @amyadcover.bsky.social!
#Koikatsu #コイカツ
Clockwise l-r: Heike (white hair, she/her), Samir (goggles, he/him) and Galatea (grey hair, she/her) in an intimate scene. Heike has just pulled out of Galatea, sending a stray rope of cum towards her back, while also pulling away from a sloppy kiss with Samir. Samir, Galatea, and Ibaraki-Douji, a large red Oni with a uniquely shaped penis, which is long enough to be smearing cum onto Galatea's head. Samir's head is trapped under Ibaraki-Douji's arm. Samir, Galatea, and Melora (she/her), in a throne room setting. Melora is cumming an obscene amount from a penis of record-breaking size, while Samir shoves his face into Melora's underarm.

Gonna be working on a commission I've been excited to do, but did a quick detour to show off Iwan again. You may remember him from last year's november-posting! #Koikatsu #コイカツ
Karl, a blond man with swept-back hair and sunglasses on his forehead (left) and Iwan, a man with sand-brown hair and a cravat (right) in a war-torn street, each covering different directions. Karl is holding a revolver, while Iwan is holding a rifle. Iwan holding up Marieta, a small girl in cozy winter gear. They are in a snowy forest, posing for a photograph. Iwan's car is visible in the background, as is Heike, who seems to be resting against the car. The image itself is desaturated and over-exposed, to give the feel of an old photograph. A POV shot of sitting across the table from Iwan. Judging by his state of undress, the clothing on the table, and the cards, The viewpoint character is playing Strip Poker with Iwan and losing quite badly.

Some old, some new. Mostly centered around Mina, Naoko's older sister and one of the less radical CEOs in @shimbolus.bsky.social's setting, The Spiral. Slowly getting better so expect more ambitious stuff soon!
#Koikatsu #コイカツ
Mina (left) and Naoko (right) in revealing bikinis, turning away and facing the camera. Naoko is aiming a pistol, while Mina is aiming her gold-coloured Channeller Magic. The beach is surrounded by a wireframe of some kind. Mina in a ridiculous impractical outfit, laying in a big armchair, watching the skyline in a lounge of some kind. Mina at the office, her jacket and blouse open, revealing a bra that's fighting for its life. Mina is staring flirtily at the camera, probably implying some kind of workplace harrassment. Yuko, Mina and Naoko on a beach, in their usual swimwear, kneeling and holding their palms open. Yuko's eyes are closed and she looks ready to recieve whatever is on offer. Mina is staring with her tongue out, enthusiastic. Naoko looks thoroughly unamused. They're waiting for soup, but they don't have any bowls. How silly.

Honestly, this is a little embarrassing to admit, but I'm still kinda sick so I haven't been able to stay awake long enough to do actual complicated pieces. These two were part of a lil request to show off Seohyun's two new outfits #Koikatsu #コイカツ
Seohyun, a blue-haired woman with a ridiculously great body (thanks to @shimbolus.bsky.social), in one of those complicated stringy bikinis. And also big long boots and gloves, and aviators. She's on a beach. Seohyun in front of a stereotypical anime high school, in a black school uniform that shows off her legs, while Polly, a smaller girl with a prosthetic arm, watches in awe. Polly is wearing a seifuku.

A bit of a quick one today but oh well. Here's Akemi, Naoko's mother. As a cheating corporate mercenary turned terrorist, she might be the most personally unpleasant OC I have! A lot of you would fold tho let's be real. #Koikatsu #コイカツ
Akemi in her younger years, a disco-loving adulterer with a dangerous gleam in her eye and a history of violence. Lots of disco lights and people in the background. Akemi (younger) outside of 'Club M', according to the sign. She's smoking and basking in the dull neon lights in the alley. Akemi (current) with Naoko, reluctantly back-to-back, with multiple black-and-orange clad assailants in the background pointing guns at them, including a whole mech.

Most of my Koikatsu work today is gonna be on characters, so I won't have much to show for it in Studio just yet, but I do have some older stuff for you. Here's Lenti, the displaced 'Queen of the Saiyans' in my little #DragonBall AU. #Koikatsu #コイカツ
Lenti, a young Saiyan woman with cracked Saiyan Battle Armor, preparing to fire a purple ki blast from one finger. She's shrugging and has an evil smug grin. Lenti firing large, jagged ki blasts and causing destruction. She has a Dragon Ball in her off-hand. Lenti, now in human fighter gear, at the World Tournament. Lenti in a little coat with a parasol in the rain. Still smug.

A beach scene. The self-insert is sitting at a little table, smushing action figures of Mikan Tsumiki and Ibuki Mioda together to make them kiss. Figures of Peko Pekoyama, Mahiru Koizumi and Chiaki Nanami lay on the same table, as well as a little island diorama. Pink haired girl in the background belongs to @Amy_ADCover

So, one part of RSE I don't talk about much is the Thousand Nations, the obligatory 'Large American Country'. Because I have to introduce lore through porn, here's Chaska, a deputy Ranger from the Diné. #Koikatsu #コイカツ
A sunset scene, with a forest, a stone house and a fence. Chaska, a man in a suit with his eyes covered by a bowler hat, leans against the house in the foreground. Two other figures in hats are talking in the background, with one of them sitting against a 1920s-styled car. An eagle stands on top of a horse in the background, to really drive in the fact that this is the America equivalent. A similar shot, but Chaska is now kneeling on the ground, clutching a rifle. One of his eyes is visible, and he has a sultry or smug expression. Ditto, underwear variant. Ditto, nude variant.

I've been watching along with FunnyWes' first-time Danganronpa playthrough and this has been my favourite bit that must sadly retire. I should update my old DR models at some point but this will suffice for The Bit. #Koikatsu #コイカツ
The scene takes place in the library room from Danganronpa: Trigger Happy Havoc. In order from left to right we have Makoto Naegi, Kyoko Kirigiri, Chihiro Fujisaki and Byakuya Togami. Makoto is holding a silver platter of cookies, Kyoko has one hand on Chihiro's shoulder, and Byakuya is fishing (what does it look like he's doing?) The dialogue is as follows: Kyoko: "Makoto, will you please bring this girl a cookie?" Makoto: "Huh? But she already has-" Kyoko: "Another." Over Byakuya's head, there is a slightly transparent version of the 'fishing' quote.

DAY 6 OF #NOVEMBER, WHERE I POST IN NOVEMBER
You ever wonder if a stranger on the street might be someone you've spoken to online? Also, I haven't used Shufeng or Dae-hyun much recently, so this is a quick fix for that. #Koikatsu #コイカツ
Two images in one. On the left, a brown-haired woman, Shufeng, sits at a multi-monitor computer setup, surrounded by 'nerdy' items, such as a fightstick and two anime figurines. She's wearing blue latex gloves, a lanyard, a white button-up, a black t-shirt stained with white, and glasses. She's got her hand up to her mouth and biting her lip, and she's blushing heavily. The caption in the corner states '39-year-old signals analyst'. On the right, a black-haired boy, Dae-hyun, checks his phone in the street. He's wearing a black and yellow stadium jacket, fingerless gloves, nail polish, and a high-tech mask with vents. He's blushing at the screen too. The caption says '21-year-old security guard'. Between them is a pair of comments from a (fake) 4chan thread. The first says "B- But Anon-chan... we're both girls... >.<", while the second replies with "i dont care... it feels right, doesnt it??". The implication is that these two are roleplaying online. Shufeng and Dae-hyun are in a public park, with strangers surrounding. Shufeng's luggage case has a sticker saying "I ❤️ Yuri", while Dae-hyun's bag has a white lily on it. They share a thought bubble, proclaiming "I fucking hate strangers. Bet this freak doesn't even fw yuri like I do."

I'm glad I could remember remember this time. Also, the most cringefail thing about RSE is that Novoselic and its whole 'Nirvana Reference' shtick is grandfathered in. I can't get rid of it now. It's been years. #Koikatsu #コイカツ
A busy street scene in the background. The foreground has Sonia, a regal-looking woman with grey-and-white streaked hair, a silver crown and a fancy outfit, crossing her arms and looking off to one side. Her green-clad guards are looking shy behind her. A disembodied hand is carrying a photograph of Sonia Nevermind from Danganronpa with the caption 'Literally Sonia'. Sonia (not the one in the photograph) is saying: "No, good fellow, I do not know what a 'Danganronpa' is. This is all original worldbuilding. Never mind what the 'inspirations' were."

Issy's sona sitting in a basic recreation of the actual room this image was made in. A large white computer desk carries a huge PC and monitor, with a wooden end-table behind Issy herself, which holds a flask, a DUALSHOCK® 4 Wireless Controller, and a coffee mug. The PC has Koikatsu's main 'creator' screen open. Don't worry about that girl behind Issy on the bed. Don't worry about that. I said don't worry.

On an unrelated note, my fucking bedframe is falling apart so now I gotta sleep in my chair. Maybe my sona jacking off tomorrow for Day 4. #Koikatsu #コイカツ
A white-haired woman, Gracie Xiao, with absurdly large breasts is in a therapy chair in a beige-walled room. She is wearing a cream and white sweater, wearing surgical gloves, and holding a mug of coffee. The room is decorated with calming plants, another coffee mug, medical instruments, a painting, and a lamp. Gracie is hefting her chest up, and staring accusatively at the POV character. Text reads: "'Rimzuri'? No, I don't believe we've spoken about this before. Tell me more. ...Oh. Okay. Ms. Liang, are we ever going to have a therapy session that doesn't end in sex? This is that avoidant behaviour I've been 'on your case' about, as you put it." Ditto, textless. Seohyun Liang, a muscular woman with blue hair and athletic clothing, recieving 'rimzuri' (a mix between paizuri and facesitting) from Gracie. Gracie is wearing spats that are covered in Seohyun's cum. The room is decorated with medical instruments, an old computer, and a window showing the city outside. Seohyun is giving a smug grin. Ditto, cumshot alt with focal lines and white reverse-vignette. Seohyun's face is less smug and more lost in the moment.
